The NASDAQ

The Nasdaq Stock Market, also known as Nasdaq or NASDAQ, is an American stock exchange located at One Liberty Plaza in New York City. It is ranked second on the list of stock exchanges by market capitalization of shares traded, behind only the New York Stock Exchange. The exchange platform is owned by Nasdaq, Inc., which also owns the Nasdaq Nordic stock market network and several U.S. stock and options exchanges.

Nasdaq is a global electronic marketplace for buying and selling securities. Nasdaq was created by the National Association of Securities Dealers (NASD) to enable investors to trade securities on a computerized, speedy and transparent system, and commenced operations on February 8, 1971. The term, “Nasdaq” is also used to refer to the Nasdaq Composite, an index of more than 3,000 stocks listed on the Nasdaq exchange that includes the world’s foremost technology and biotech giants such as Apple, Google, Microsoft, Oracle, Amazon, and Intel.

Origins of Nasdaq

Nasdaq officially separated from the NASD and began to operate as a national securities exchange in 2006. In 2007, it combined with the Scandinavian exchange group OMX to become the Nasdaq OMX group, which is the largest exchange company globally, powering 1 in 10 of the world’s securities transactions.

Headquartered in New York, Nasdaq OMX operates 25 markets – primarily equities, and also including options, fixed income, derivatives and commodities – as well as one clearinghouse and five central securities depositories in the U.S. and Europe. Its cutting-edge trading technology is used by 70 exchanges in 50 countries. It is listed on the Nasdaq under the symbol NDAQ and has been part of the S&P 500 since 2008.

The Nasdaq computerized trading system was initially devised as an alternative to the inefficient “specialist” system, which had been the prevalent model for almost a century. The rapid evolution of technology has made the Nasdaq’s electronic trading model the standard for markets worldwide.

As a leader in trading technology from the outset, it was only fitting that the world’s technology giants chose to list on the Nasdaq in their early days. As the technology sector grew in prominence in the 1980s and 1990s, the Nasdaq became the most widely followed proxy for this sector. The technology and dot-com boom and bust of the late 1990s is exemplified by the rise and fall of the Nasdaq Composite during this period. The index crossed the 1,000 mark for the first time in July 1995, soared in the following years and peaked at over 4,500 in March 2000, before slumping almost 80% by October 2002 in the subsequent correction.

Recent History of Nasdaq

In February, 2011, in the wake of an announced merger of NYSE Euronext with Deutsche Börse, speculation developed that NASDAQ OMX and Intercontinental Exchange (ICE) could mount a counter-bid of their own for NYSE. At the time, NYSE Euronext’s market value was $9.75 billion. Nasdaq was valued at $5.78 billion, while ICE was valued at $9.45 billion. Late in the month, Nasdaq was reported to be considering asking either ICE or the Chicago Mercantile Exchange to join in what would probably have to be, if it proceeded, an $11–12 billion counterbid.

The European Association of Securities Dealers Automatic Quotation System (EASDAQ) was founded as a European equivalent to the Nasdaq Stock Market. It was purchased by NASDAQ in 2001 and became NASDAQ Europe. Operations were shut down, however, as a result of the bursting of the dot-com bubble. In 2007, NASDAQ Europe was revived as Equiduct, and it is currently operating under Börse Berlin.

On June 18, 2012, Nasdaq OMX became a founding member of the United Nations Sustainable Stock Exchanges initiative on the eve of the United Nations Conference on Sustainable Development. In November 2016, Nasdaq Chief Operating Officer Adena Friedman was promoted to the role of CEO, becoming the first woman to run a major exchange in the U.S. In 2016, Nasdaq earned $272 million in listings-related revenues.

Nasdaq achieved its highest-ever close on August 29, 2018, when its index peaked at 8109.69. In 2018, it was announced that the Nasdaq was planning to introduce cryptocurrency futures the next year in conjunction with a prominent investment firm.

Investors Types, Passive Investors vs. Active Investors

Investors are individuals or entities that allocate capital with the expectation of receiving financial returns. This group encompasses a wide range of entities including individuals, companies, pension funds, and governments, who invest in various financial instruments such as stocks, bonds, real estate, and mutual funds, among others. The primary goal of investors is to generate income or increase their initial capital over time through the appreciation of the investment’s value. They play a crucial role in the financial markets by providing capital to businesses and governments, facilitating economic growth and innovation. Investors vary in their risk tolerance, investment horizon, and strategies, ranging from conservative approaches focusing on stable, income-generating assets to aggressive strategies seeking high returns through riskier investments.

Types of Investors:

  • Retail Investors

These are individual investors who invest their own money in various financial instruments like stocks, bonds, mutual funds, or exchange-traded funds (ETFs). They typically have smaller amounts to invest compared to institutional investors and may not have the same level of access to information or financial advice.

  • Institutional Investors

These are large organizations that invest substantial sums of money on behalf of their members or clients. Examples include pension funds, insurance companies, mutual funds, and endowments. Due to their size and expertise, they have significant influence in the markets and access to exclusive investment opportunities.

  • High Net Worth Individuals (HNWIs)

Individuals with significant personal wealth, often defined by having investable assets exceeding a certain threshold, excluding personal assets and property like primary residences. HNWIs typically have access to specialized investment products and may employ private wealth managers to oversee their portfolios.

  • Angel Investors

Wealthy individuals who provide capital for business startups, usually in exchange for convertible debt or ownership equity. Angel investors not only offer financial backing but may also provide valuable mentorship and access to their network to help the business grow.

  • Venture Capitalists (VCs)

Professional group or firms that invest in high-growth potential startups and early-stage companies in exchange for equity, or an ownership stake. VCs are looking for businesses with the potential to offer a high return on investment and are often involved in the strategic planning of their investee companies.

  • Private Equity Investors

Investors or funds that invest directly into private companies or conduct buyouts of public companies, taking them private. Private equity investing is typically a longer-term investment strategy focused on restructuring or expanding businesses to sell them or take them public in the future at a profit.

  • Hedge Funds

Investment funds that pool capital from accredited investors or institutional investors and employ a wide range of strategies to earn active returns for their investors. Hedge funds are known for their flexibility in investment strategies, including the use of leverage, short selling, and derivatives to amplify returns.

  • Mutual Fund Investors

Individuals or institutions that invest in mutual funds, which are professionally managed investment programs that pool money from many investors to purchase a diversified portfolio of stocks, bonds, or other securities. Mutual funds offer diversification and professional management but come with management fees.

  • Index Fund Investors

Investors who put their money into index funds, a type of mutual fund or ETF designed to track the components of a market index, like the S&P 500. Index funds are known for their low turnover, lower management fees, and tax efficiency.

  • Day Traders

Individuals who buy and sell financial instruments within the same trading day. Day traders aim to make profits from short-term price movements and often use leverage to amplify their investment capital. This type of trading requires a significant time investment and a deep understanding of market movements.

  • Algorithmic Traders

Traders who use computer algorithms to automate trading decisions based on specified criteria, such as price movements or market timing strategies. Algorithmic trading can execute orders faster and more efficiently than manual trading and is used by individual traders and institutional investors alike.

Passive Investors Vs. Active Investors

Basis of Comparison Passive Investors Active Investors

Stress prevention mechanism

Stress management starts with identifying the sources of stress in your life. This isn’t as easy as it sounds. Your true sources of stress aren’t always obvious, and it’s all too easy to overlook your own stress-inducing thoughts, feelings, and behaviors. Sure, you may know that you’re constantly worried about work deadlines. But maybe it’s your procrastination, rather than the actual job demands, that leads to deadline stress.

To identify your true sources of stress, look closely at your habits, attitude, and excuses:

  • Do you explain away stress as temporary (“I just have a million things going on right now”) even though you can’t remember the last time you took a breather?
  • Do you define stress as an integral part of your work or home life (“Things are always crazy around here”) or as a part of your personality (“I have a lot of nervous energy, that’s all”).
  • Do you blame your stress on other people or outside events, or view it as entirely normal and unexceptional?

Until you accept responsibility for the role you play in creating or maintaining it, your stress level will remain outside your control.

Start a stress journal

A stress journal can help you identify the regular stressors in your life and the way you deal with them. Each time you feel stressed, keep track of it in your journal. As you keep a daily log, you will begin to see patterns and common themes. Write down:

  • What caused your stress (make a guess if you’re unsure).
  • How you felt, both physically and emotionally.
  • How you acted in response.
  • What you did to make yourself feel better.

Look at how you currently cope with stress

Think about the ways you currently manage and cope with stress in your life. Your stress journal can help you identify them. Are your coping strategies healthy or unhealthy, helpful or unproductive? Unfortunately, many people cope with stress in ways that compound the problem.

Unhealthy ways of coping with stress

These coping strategies may temporarily reduce stress, but they cause more damage in the long run:

  • Smoking
    • Drinking too much
    • Overeating or undereating
    • Zoning out for hours in front of the TV or computer
    • Withdrawing from friends, family, and activities
    • Using pills or drugs to relax
    • Sleeping too much
    • Procrastinating
    • Filling up every minute of the day to avoid facing problems
    • Taking out your stress on others (lashing out, angry outbursts, physical violence)

Learning healthier ways to manage stress

If your methods of coping with stress aren’t contributing to your greater emotional and physical health, it’s time to find healthier ones. There are many healthy ways to manage and cope with stress, but they all require change. You can either change the situation or change your reaction. When deciding which option to choose, it’s helpful to think of the four As: avoid, alter, adapt, or accept.

Since everyone has a unique response to stress, there is no “one size fits all” solution to managing it. No single method works for everyone or in every situation, so experiment with different techniques and strategies. Focus on what makes you feel calm and in control.

Dealing with Stressful Situations: The Four A’s

Change the situation:

  • Avoid the stressor.
  • Alter the stressor

Change your reaction:

  • Adapt to the stressor.
  • Accept the stressor.

Stress Management Through Mind Control and Purification

People can learn to manage stress and lead happier, healthier lives. Here are some tips to help you keep stress at bay.

  • Keep a positive attitude.
  • Accept that there are events that you cannot control.
  • Be assertive instead of aggressive. Assert your feelings, opinions, or beliefs instead of becoming angry, defensive, or passive.
  • Learn and practice relaxation techniques; try meditation, yoga, or tai-chi for stress management.
  • Exercise regularly. Your body can fight stress better when it is fit.
  • Eat healthy, well-balanced meals.
  • Learn to manage your time more effectively.
  • Set limits appropriately and learn to say no to requests that would create excessive stress in your life.
  • Make time for hobbies, interests, and relaxation.
  • Get enough rest and sleep. Your body needs time to recover from stressful events.
  • Don’t rely on alcohol, drugs, or compulsive behaviors to reduce stress.
  • Seek out social support. Spend enough time with those you enjoy.
  • Seek treatment with a psychologist or other mental health professional trained in stress management or biofeedback techniques to learn healthy ways of dealing with the stress in your life.

Stress Management Intervention Primary, Secondary and Tertiary

Primary Intervention

Actions at the primary level directly target the causes or sources of stress that are present within an organization in order to reduce or completely eliminate them. The aim is to reduce the possibility of developing mental health problems by reducing workers’ exposure to the risks in their work environment.

For example, it is known that lack of participation in the decision-making process has consequences for the mental health of individuals. Thus, an organization that wishes to undertake primary prevention could establish a mechanism which gathers the suggestions and requests of individuals, analyzes them, and applies them within the work environment with the participation of these individuals. In this way, the organization helps to reduce employees’ exposure to this risk factor and to prevent the development of work-related mental health problems.

Advantages and disadvantages

Primary prevention strategies are the only ones that reduce or eliminate mental health problems at work at their source. Because these strategies directly attack the causes of the problem, they will also considerably reduce their resulting costs. However, such significant results will require a real commitment from the organization. This explains why such strategies are used less often. It takes time and energy to eliminate the risks present in the workplace. Sometimes several months go by before the positive effects of primary strategies can be seen. Financial, human and technical resources are also required.

Such strategies require support by upper management and the commitment of all persons concerned. They must be part of a well planned and structured process. Ensuring the success of such an undertaking is a major challenge. For example, the development and functioning of the decision-making process described above can be expected to take some time and require the mobilization of human and technical resources. A system has to be implemented to gather suggestions made by employees, as well as to analyze, choose and apply them within the work environment. All these steps require significant effort and cannot be accomplished overnight.

Although implementing primary level strategies normally requires time, energy and resources, this is not always the case. Sometimes improvements can be made by simply adapting certain existing management practices within the organization. Team meetings are a good example. Several organizations hold weekly or monthly meetings with their employees. Not much is required to make these meetings an occasion to give employees recognition and support, and to facilitate feedback. In addition, an organization that wants to encourage the participation of employees in the decision-making process could use these meetings to gather requests and suggestions from employees until such time that an official process is implemented.

Secondary prevention:

Secondary prevention aims to help individuals develop the knowledge and skills to better recognize and manage their reactions to stress. Giving them the necessary tools allows them to better adapt to the situation or to the work environment and reduces the impact of stress. The content and form of these strategies may vary considerably but they usually include awareness and information-sharing activities, as well as skills development programs.

Advantages and disadvantages

Secondary prevention strategies are a useful tool because they make individuals aware of and inform them about the problem of mental health at work. These strategies also help them develop their skills and their mental resources in order to increase their resistance to stress.

However, secondary prevention strategies do not change the conditions in which work is performed. They only deal with the consequences of the problem in order to control the damage. This is why such strategies only have short-term effects. For example, while stress management training changes people’s reaction so that they can better adapt to their work, it does not eliminate the sources of stress within an organization.

Many firms that until now have relied exclusively on this type of strategy now realize that they are unable to adequately fight against work-related mental health problems. In order for secondary prevention strategies to be totally effective, they must be combined with primary and tertiary strategies.

Tertiary prevention

Tertiary prevention strategies aim to treat and rehabilitate persons as well as facilitate a return to work and the follow up of those who suffer or have suffered from a work-related mental health problem. These strategies generally include counselling services to refer employees to specialists if need be. Tertiary prevention activities are often part of employee assistance programs. These programs feature personalized client-centred help for persons with difficulties so they can analyze their problems and feel supported in their search for solutions. These strategies may also include return-to-work programs for employees who are on sick leave, as well as a help network for example, informal caregivers who can provide support, active listening and referrals to professional resources if necessary.

Advantages and disadvantages

In spite of the fact that the quality and quantity of services vary from one organization to another, they generally help individuals who have personal difficulties or work-related difficulties to obtain information, help and support from in-house counsellors and from counsellors outside the organization. Tertiary level services are voluntary, confidential and available at all times.

As far as drawbacks are concerned, tertiary activities, just like secondary ones, are centred on the person rather than the work situation. By trying to reduce the symptoms, once again they target only the consequences of the problem. Furthermore, because the Employee Assistance Program (EAP) is confidential, it cannot deal with organizational causes.

Return-to-work program

  • Maintains the employment relationship with the person on leave;
  • Return-to-work plan;
  • Employment support measures (for example: progressive return to work, temporary assignments, medical follow up).

Peer help networks

  • Active listening;
  • Information;
  • Support;
  • Referrals to specialized resources.

Employee assistance programs (EAP)

  • Information;
  • Assessing needs;
  • Short-term help through individual or group meetings;
  • Telephone support line;
  • Referrals to specialized resources (doctors, psychologists, psychiatrists, social workers, guidance counsellors, lawyers).

Role of Pranayama, Mantras, Nutrition, Music

Pranayama

Pranayama state as “control of breath” calms the disturbed pattern of breathing which agitates the mind and senses. It is an important therapeutic method for promoting healing on all levels.

Mind and breath are linked together like a bird with two wings. In the same manner breath can be used as a rope to tie down the mind. If we concentrate on the breath, the mind becomes internalized. The process of Pratyahar means withdrawal from the senses and its external orientation on the outer world and made to turn inward. In this ways Pranayama is one of the best means of Pratyahar.

Awareness of breath is a door to the deeper levels of the mind. As the mind focuses on the breath, the deeper layers of consciousness gradually open, releasing the subconscious and all that is hidden within. The process of mind draws more energy during Pranayama, deeper thoughts come up, and emotional issues helps to deal or sit in meditation or their energy will disturb us and prevent us from going deeper. It should be never be attempted willfully or forcefully but as part of a process of deepening inner peace and equanimity. To deal with it properly requires the proper foundation of Yamas and Niyamas first.

Mantras

Mantra meditation is one of the simplest and easiest-to-learn meditation techniques. Like other forms of meditation, it can change your stress levels at the moment with a single session or can change the way you manage stress from now on with repeated practice. And it has the benefit of being simple to learn and customize to meet your specific needs for stress management.

Benefits of Mantra Meditation

If you are reading this, you have probably already heard that meditation is a powerhouse of a stress reliever because of all of the ways it can improve your outlook and overall health. 

Meditation has been linked to a reduction of chronic stress as well as decreases in heart rate and blood pressure, an increase in immune system functionality, and many other benefits.

Mantra meditation, in particular transcendental meditation, has also been linked with a decrease in intrusive thoughts, and an increase in meaning and quality of life in HIV patients.

 It has been linked to reduced stress, anxiety and anger and increases in quality of life in nurses. Another study on veterans found that mantra meditation reduces the occurrence of intrusive thoughts and minimizes stress as well.2 Many people find that mantra meditation is simpler to master when they are starting out because it provides an empowering focal point; many people find it difficult to keep redirecting their thoughts to the present moment and instead feel that it is easier to have something more specific to grasp onto.

The bottom line is, with mantra meditation, you may feel less stressed after one session. With repeated practice, you may find yourself less reactive to future stress. Practicing mantra meditation is easy. Here’s how:

  1. Set Aside a Few Minutes and Get into a Comfortable Position
  • At first, it’s best to have a quiet room, free of distractions. With repeated practice, you may find yourself able to practice mantra meditation anywhere and under more chaotic circumstances.
  1. Choose a Mantra for Meditation
  • A mantra is a word or phrase that you repeat to yourself out loud or silently. It can be a more classically significant spiritual word like the Hindu, ‘Aum,’ (aka Om) or it can be a word or phrase like, ‘Calm’ or ‘I am at peace.’ The words or sounds you choose aren’t important as long as they are simple and comfortable for you to repeat.
  1. Close Your Eyes and Repeat Your Mantra to Yourself
  • As you do so, try to focus only on the sound and feel of your mantra and nothing else. If you find other thoughts creeping into your head, thank yourself for noticing, and gently redirect your attention to your mantra.
  1. Continue for Several Minutes
  • That’s it. Just continue to repeat your mantra and focus on the sound and the way it feels to make the sound. Redirect your attention away from distractions, and back to your mantra. You can start with 5- or 10-minute sessions and work up to 20 or 30; with mantra meditation, any practice time is better than none.

Nutrition

Good nutrition is an important stress management tool. When our bodies are poorly fed, stress takes an even greater toll on our health. Nutrition and stress are interlinked. Here are some tips to eat well for academic success:

  • Eat regularly. Your brain needs glucose to work at its best. Eating regularly throughout the day helps keep your blood glucose stable. Studies have shown that more stable blood sugar levels are associated with better academic performance.
  • Get your healthy fats. Omega-3 fatty acids found in walnuts, flax seed and fish oil are associated with brain function. Deficiencies of this fatty acid can result in depression and/or anxiety.
  • Eat your veggies. Fruits and vegetables contain vitamins and minerals like copper, zinc, manganese, and vitamins A, E and C. Leafy greens are especially good for you. These vitamins and minerals work to neutralize harmful molecules produced when your body is under stress.
  • Add high-fiber foods. High fiber intake has been associated with greater alertness and decreased perceived stress. So add fiber-rich foods like oatmeal, nuts, beans, fruits and vegetables to your diet.
  • Trade caffeine for more sleep. Caffeine leads to increased blood pressure and may make you anxious, especially if you are already prone to anxiety. While consuming caffeine may seem to help you concentrate better, some studies show that caffeine only restores what is lost through lack of sleep. Instead of turning to caffeine, try the natural grade booster – sleep!
  • Stock up on healthy snacks. If you know that a stressful or busy time is approaching, prepare by stocking up on quick, healthy snacks. Healthy snacks are high in protein and/or fiber. Some examples are low fat granola, almonds, peanuts, carrots with hummus or yogurt with fresh fruit.

Music

The soothing power of music is well-established. It has a unique link to our emotions, so can be an extremely effective stress management tool.

Listening to music can have a tremendously relaxing effect on our minds and bodies, especially slow, quiet classical music. This type of music can have a beneficial effect on our physiological functions, slowing the pulse and heart rate, lowering blood pressure, and decreasing the levels of stress hormones. Music, in short, can act as a powerful stress management tool in our lives.

As music can absorb our attention, it acts as a distraction at the same time it helps to explore emotions. This means it can be a great aid to meditation, helping to prevent the mind wandering.

Musical preference varies widely between individuals, so only you can decide what you like and what is suitable for each mood. But even if you don’t usually listen to classical music it may be worth giving it a try when selecting the most calming music.

When people are very stressed, there is a tendency to avoid actively listening to music. Perhaps it feels like a waste of time, not helping to achieve anything. But as we know, productivity increases when stress is reduced, so this is another area where you can gain vast rewards. It just takes a small effort to begin with.

To incorporate music into a busy life, try playing CDs in the car, or put the radio on when in the bath or shower. Take portable music with you when walking the dog, or put the stereo on instead of the TV. A person with clinical depression or bipolar disorder might listen to music to help with their worst, lowest moods.

Singing (or shouting) along can also be a great release of tension, and karaoke is very enjoyable for some extroverts! Calming music before bedtime promotes peace and relaxation and helps to induce sleep.

Research on Music

Music has been used for hundreds of years to treat illnesses and restore harmony between mind and body. But more recently, scientific studies have attempted to measure the potential benefits of music.

Models of Stress Management Transactional Model, Health Realization/ Innate Health Model

The Transactional Model

In 1984, Richard Lazarus and Susan Folkman proposed the Transactional Model (Cognitive Appraisal), a model that emphasizes how stress becomes the result of the imbalance between what the situation demands and what the person possesses in relation to those demands. According to them, stress is not directly resulting from the source of the stress otherwise known as the stressors; rather, it emerges because of the individual’s inability to satisfy demands. For these two researchers, therefore, stress management relates to the capacity of a person to utilize his resources in order to cope with the stress.

The Transactional Model tells us that a stress management program can only become effective if the individual’s ability to eliminate, reduce, or cope with stress is successful assessed, and that the factors related to such capacity are put into consideration.

Health Realization Model

Also called as the Innate Health Model of Stress, the Health Realization Model states that the presence of a probable stressor does not directly result to the stress experience. This idea was opposing that of the Transactional Model, because it states that the stress management program must be cantered on the perception of the potential stressor by the individual, not on his appraisal of stress coping abilities.

According to this model, the appraisal must be focused on filtering one’s mind of negativity an insecurity, so that he would not perceive a potential stressor as a source of stress, and would therefore lead to a more effective elimination or reduction of stress.

Stress Management Techniques

More and more people have realized their need to handle stress in a more effective way , which is why it is nearly impossible to identify all the stress management techniques applied by each of us. Nevertheless, here are the mostly recognized techniques on stress management:

  • Exercise
  • Starting a New a Hobby
  • Meditation
  • Autogenic training
  • Artistic Expression
  • Fractional relaxation
  • Progressive relaxation
  • Spas
  • Alternative/ natural medicine
  • Social activity
  • Cognitive therapy
  • Conflict resolution
  • Deep breathing
  • Reading novels
  • Prayer
  • Relaxation techniques
  • Listening to Music
  • Yoga

Meditation meaning and Importance

The word meditation is derived from the Latin word Meditari, meaning “to think, “contemplate”, “devise”, or “ponder”. Today, meditation has become extremely popular all over the world. In general, most of the time it has been used to reduce stress, to promote wellness and healing. There are more than 2500 research studies available on meditation. In the last 200 years, different meditation techniques are derived from the traditional Yoga texts and promoted by the Yoga masters and spiritual leaders.

Although the ultimate goal of meditation is same (calming the mind) the paths are different. However, in the west, meditation is considered as a relaxation technique to promote wellness and healing. The Upanisads emphasis on selfanalysis through intellect and establish the mind on self. Lord Krishna in Bhagavad Geeta says, ‘meditate on the Supreme Self by directing all the senses towards inside using the intellect’. Perhaps, the most profound description of meditation is found in Patanjali Yoga Sutra. Sage Patanjali describes Añöäìga Yoga (eight limbs of Yoga) to realize the ultimate. The sixth and the seventh limb of añöäìga Yoga are pertaining to meditation.

Dharana and Dhyana may be considered as the last two of four stages, which form a continuum in the process and practice of meditation. Hatha Yoga gives the description of the practice of meditation and its benefits. Tantra presents 112 of meditation techniques to realize the ultimate.

Meditation is a distinct practice in Indian philosophy and it is mentioned in many Indian traditional texts. The first description of meditation occurs in Vedas which is one of the oldest scriptures of Hindu culture. Meditation was a part of daily life and known to everyone during Vedic age. Recently, the archaeologists have discovered the sculptures in meditative pose in the ancient civilization, Mohenjo-Daro and Harappa. Specific meditation techniques have been developed for the convenience in the later period.

A restless mind is like a lake, constantly agitated by the winds of desires, creating thought-waves of diverse nature. Because of this constant agitation, our true Self at the bottom of the lake cannot be perceived. To subside all thought-waves, a single thought is consciously cultivated by the repeated and uninterrupted practice of meditation. Then, the lake (mind) becomes calm and bottom of lake (ätman) becomes visible.

Meditation is keeping the mind focused uninterruptedly on a subject for a certain length of time. It is a mental process by which meditator becomes one with the object of meditation. Meditation is the seventh stage in Astanga Yoga of Patanjali.

Meditation is an antidote to stress

  • The Neuro chemistry and Neuro physiology of meditation is just the reverse of stress. Stress: Over activity of Sympathetic system.
  • Meditation: Over activity of Parasympathetic system.

Caution

  • However, it is not a push button system, one need patience. Hence there is a 90 to 95% -drop out rate. One needs to have right guide, right method, correct understanding, appropriate place, constant practice, extreme faith and full conviction.
  • Please do not sleep.
  • Meditation industry is at height, because of commercialization, so one should be careful.
  • Not to make comparisons, all systems are great

It means Meditation is the art of living in the present. Human beings normally choose to recollect past or predict future rather than think about present. This attitude leads to the vicious circle of hopes, failures, regrets and tensions. Meditation leads us to stay with the time thereby keeping us away from past or future.

Measurement of Stress Reaction: The Physiological Response, The Cognitive Response, The Behavioural Response

The Physiological Response

The process of physiological stress response starts from the moment the body realizes the presence of the stressor, followed by the sending of signals to the brain, and to the specific sympathetic and hormonal responses to eliminate, reduce or cope with the stress.

The Nervous System

When your body senses that a particular stressor is present, signals about that stimulus are sent to your brain. The master gland called the hypothalamus is then alerted to arouse the Autonomic Nervous System (ANS). The ANS is the system which controls most of the major organs of your body: the heart, lungs, stomach, glands and even the blood vessels. With these organs, you’ll readily notice that the ANS is responsible for the unconscious regulation of the heart beat and breathing.

Sympathetic Response

The SNS surely likes things to go very quickly when you are faced with stress. The neurotransmitter noradrenaline is released by the nerve endings and is sent to the SNS so that the latter can:

  • Enhance the strength of your skeletal muscles. Have you heard news about people who were able to carry heavy furniture or equipments outside their house during fire? Well, fire is a very stressful situation, and thankfully we have our sympathetic response to aid us during these circumstances.
  • Increase heart rate. During stressful moments, your heart beats faster than it usually does so that the parts of your body which are needed to cope up with the stress would be supplied by enough oxygenated blood to remain functional until the stressful situation subsides.
  • Shoot up sugar and fat levels. We all know that sugar and fat provides our body with energy. During stressful situations, we need more energy to cope up, and so the SNS assists us to have more energy.

Hormonal Response

Other than the nervous system, the body’s stress response also includes the help of the adrenal glands. Situated on top of each kidney, the adrenal glands are also included in the physiologic stress response because the adrenal medulla (the centre part of the glands) has nerves that connect the gland to the SNS. The SNS stimulates the adrenal medulla to start releasing adrenaline and noradrenaline into the blood circulation. This action results in the “fight or flight” response, which is manifested by the increase in heart rate, dilation of bronchial airways and enhancement of the metabolic rate so more of the stored energy can be used.

The Cognitive Response

Despite evidence that psychological stress is an important risk factor for age-related cognitive loss, little research has directly evaluated psychological and physiological mediators of the relationship between stressful experiences and cognitive function. A key objective of the ESCAPE (Effects of Stress on Cognitive Aging, Physiology, and Emotion) project is to evaluate whether engaging in stress-related unconstructive repetitive thought (URT) is a pathway through which stressful experiences negatively affect cognitive health over the short- and long-term. Over the short-term, we hypothesize that engaging in URT will deplete attentional resources and result in worse cognitive performance in daily life. Over the long-term, we expect that the effects of chronic stress, from repeated exposure to stressors and regular engagement in URT, will be apparent in dysregulated hypothalamic-pituitary-adrenal (HPA) axis function and inflammation. Over time, stress-related physiological dysregulation will result in accelerated cognitive decline.

Cognitive symptoms of stress include:

  • Constant worrying
  • Racing thoughts
  • Forgetfulness and disorganization
  • Inability to focus
  • Poor judgment

The Behavioural Response

Behavioural responses to stress are evoked from underlying complex physiological changes that arise consequently from stress.

Real or perceived threat in the environment elicits stress response in animals, which disrupts internal homeostasis. Physiological changes cause behavioural responses in animals, including: impairment of response inhibition and lack of motivation, as well as changes in social, sexual, aggression and nurture behaviour in animals. The extent of the impact is dependent upon the type and duration of the stress, as well as the animal’s past experiences. Behavioural responses to prolonged stress can also be transferred across generations.

Behavioural responses

Behavioural responses to stress are evoked from some underlying complex physiological changes that arise consequently from stress.

Impairment of response inhibition and lack of motivation

According to a study conducted by Mika and his colleagues, prolonged stress in rats causes response inhibition. It was evident through their experiment that stressed rats had inhibited premature responses (decreased timing of intervals to food), along with decreased intrinsic motivation to initiate a response. They link the decreased motivation to the stress-associated reduction in incentive motivation, as presented by another study conducted by Kleen and his colleagues. Decreased motivation was also seen in a study conducted by Beery and Kaufer, where they explained that stressed rodents are less likely to be motivated to interact with one another.

Change in social behaviours

Beery and Kaufer noted that social withdrawal and general reduction in social interaction after an exposure to a stressor are evident in rodents. They argue that this is due to the underlying physiological changes that the rodent goes through in response to stress. For instance, the changes that occur to the hypothalamic-pituitary-adrenal (HPA) hormonal axis is directly related to the changes in social behaviour. Social avoidance is another consequence of stress that can be seen in rodents. Rodents are more likely to avoid dominant rats and avoid social interactions amongst each other after the exposure to a stressor.

Sexual behaviours

Sexual interests change in many species when exposed to stressors. For instance, stressed male and female rats express inhibited mating behaviour, which is evident through the clear increase in the inhibitory hormone RF-amide. Another study suggests that masculine sexual behaviour in male rats is subject to changes in accordance to the type of stressors that the rats were subjected to. The female zebra finch’s mating choice is determined by the stressors that they are exposed to early in life, which remain consistent throughout adulthood. A study about stress effects on female songbird’s response to sexual signal for mating indicated that the response to this specific signal can be impaired if the female is exposed to developmental stress. Behavioural changes as a result from developmental stress impairs neural responses to sexual signals, which reduces mating.

Aggressive behaviours and anti-predator responses

Stressed animals would choose to avoid a novel situation rather than confront it. Aggressive behaviour is associated with sex hormones, such as testosterone, and specific brain regions and systems, such as the medial preoptic nucleus, prefrontal cortex-dependent response inhibition, and anterior hypothalamus. Stress negatively impacts sex hormones, which results in an imbalance and reduction in aggression related hormones and function. Also, chronic stress results in prefrontal cortex-dependent response inhibition. This results in reduction in aggression, thus promoting anti-predator responses.

Prolonged stress reduces parental behaviour toward offspring

Prolonged stress alters parental behaviour toward offspring and promotes parental neglect. According to a study performed by Tilgar and associates, predation stress alters parents’ behaviours, such as the reduction in provisioning rates, which negatively impacts the offspring’s performance. The hormones oxytocin and vasopressin are generally responsible for affiliative and pair-bonding behaviours in many species. Stress alters the level of both hormones, resulting in an abnormal behaviour from parents towards offspring. For instance, levels of oxytocin decrease as a result of prolonged stress, which has been shown to reduce pair-bonding behaviour and increase withdrawal behaviour. Prolactin is another important hormone that is associated with nurture by parents to offspring, and levels of this hormone can be altered as a result of stress. Reduced levels of prolactin as a result of stress decreases behaviours such as suckling, licking, and brooding.

General Adaption Syndrome (GAS) Concept & Stages

Stress is a common occurrence. While you can’t remove every single stressor from your life, it’s possible to manage stress and maintain your health. This is important because stress can cause mental fatigue, irritability, and insomnia.

But even if you know the physical effects of stress, you may be unaware of the different stages of stress, known as general adaptation syndrome (GAS). When you understand the different stages of stress and how the body responds in these stages, it’s easier to identify signs of chronic stress in yourself.

GAS is the three-stage process that describes the physiological changes the body goes through when under stress. Hans Selye, a medical doctor and researcher, came up with the theory of GAS. During an experiment with lab rats at McGill University in Montreal, he observed a series of physiological changes in the rats after they were exposed to stressful events.

With additional research, Selye concluded that these changes were not an isolated case, but rather the typical response to stress. Selye identified these stages as alarm, resistance, and exhaustion. Understanding these different responses and how they relate to each other may help you cope with stress.

General adaptation syndrome stages

  1. Alarm reaction stage

The alarm reaction stage refers to the initial symptoms the body experiences when under stress. You may be familiar with the “fight-or-flight” response, which is a physiological response to stress. This natural reaction prepares you to either flee or protect yourself in dangerous situations. Your heart rate increases, your adrenal gland releases cortisol (a stress hormone), and you receive a boost of adrenaline, which increases energy. This fight-or-flight response occurs in the alarm reaction stage.

  1. Resistance stage

After the initial shock of a stressful event and having a fight-or-flight response, the body begins to repair itself. It releases a lower amount of cortisol, and your heart rate and blood pressure begin to normalize. Although your body enters this recovery phase, it remains on high alert for a while. If you overcome stress and the situation is no longer an issue, your body continues to repair itself until your hormone levels, heart rate, and blood pressure reach a pre-stress state.

Some stressful situations continue for extended periods of time. If you don’t resolve the stress and your body remains on high alert, it eventually adapts and learns how to live with a higher stress level. In this stage, the body goes through changes that you’re unaware of in an attempt to cope with stress.

Your body continues to secrete the stress hormone and your blood pressure remains elevated. You may think you’re managing stress well, but your body’s physical response tells a different story. If the resistance stage continues for too long of a period without pauses to offset the effects of stress, this can lead to the exhaustion stage.

Signs of the resistance stage include:

  • Irritability
  • Frustration
  • Poor concentration
  1. Exhaustion stage

This stage is the result of prolonged or chronic stress. Struggling with stress for long periods can drain your physical, emotional, and mental resources to the point where your body no longer has strength to fight stress. You may give up or feel your situation is hopeless. Signs of exhaustion include:

  • Fatigue
  • Burnout
  • Depression
  • Anxiety
  • Decreased stress tolerance

The physical effects of this stage also weaken your immune system and put you at risk for stress-related illnesses.

GAS can occur with any type of stress. Stressful events can include:

  • A job loss
  • Medical problems
  • Financial troubles
  • Family breakdown
  • Trauma

But while stress is unpleasant, the upside is that GAS improves how your body responds to stressors, particularly in the alarm stage.

The fight-or-flight response that occurs in the alarm stage is for your protection. A higher hormone level during this stage benefits you. It gives you more energy and improves your concentration so you can focus and tackle the situation. When stress is short-term or short-lived, the alarm stage isn’t harmful.
