What Do you Mean by Stress?

Stress is the body's response to any sort of demand, whether it is real or imagined. It makes the person feel threatened or challenged. When someone is stressed, the body's "fight or flight" response is activated, which results in the release of hormones like adrenaline and cortisol. It is made available to the person in order to help them deal with this demand or challenge. It is important to study because it is a major factor in many illnesses. It can also affect how people think, behave and feel.


Here are Some Different Types of Stress:

  1. Acute Stress: This is the most common type of stress. It is usually caused by a sudden event, such as an emergency or a traumatic experience. Acute stress can be very helpful in some situations because it gives you the energy to deal with the situation that is causing it. However, if it lasts for too long, it can become harmful.

  2. Chronic Stress: Chronic stress is a type of stress that lasts for a long time and doesn't go away. It can be caused by things like work, family problems or money troubles. Chronic stress can have negative effects on your health and well-being.

  3. Physical Stress: Physical stress is caused by physical factors, such as noise, heat or cold. It can also be caused by unpleasant odours and bright lights.

  4. Chemical Stress: Chemical stress is the type of stress that you get from being exposed to harmful chemicals, such as radiation or paint fumes. It can also be triggered when your body doesn't have enough nutrients to maintain its normal functions. This usually happens in cases where a person's diet isn't very healthy or balanced.

  5. Environmental Stress: Environmental stress comes from factors like pollution, traffic noise and overcrowding in cities. People who live in these types of conditions are more likely to feel stressed out than people living somewhere else because their environment affects them so much more directly on a daily basis.

  6. Emotional/Psychological Stress: Emotional or psychological stress comes from emotional factors, such as grief, anxiety and depression. People who feel overwhelmed by these types of emotions can find themselves unable to deal with the stress that they cause.

  7. Behavioural Stress: Behavioural stress is caused by behaviours like working too much or having a bad work-life balance. It is often related to burnout, which occurs when you are overworked and stressed out for so long that your body stops functioning properly. This type of stress isn't good for your health because it usually leads to things like heart disease or obesity.

  8. Cognitive Stress: Cognitive stress comes from thinking patterns that affect how we perceive events in our lives, resulting in us feeling stressed about them even though there may be nothing actually wrong with what's happening at all. Cognitive stress can be caused by things like perfectionism, low self-esteem and negative thinking.

  9. Social Stress: Social stress is the type of stress that you get from being in a bad relationship or having poor communication with people close to you. This kind of stress usually happens because we let our relationships affect us too much and don't think about how they're affecting us until it's too late.

  10. Stress From Pressure/Tension: Stress from pressure or tension comes from feeling pressured into doing something even though there aren't enough resources available for it to happen properly. It can also come from situations where someone expects way too much out of one person without giving them any help along the way so that they are overwhelmed as a result.

  11. Time Pressure Stress: Time pressure stress is caused by the feeling that you don't have enough time to do everything that you need to do. This type of stress can be very harmful because it makes you feel like you're always behind and can never catch up.

  12. Financial Stress: Financial stress is the type of stress that comes from money problems. It can be caused by things like being in debt, not having enough money to live on or struggling to pay bills. Financial stress can be very stressful and overwhelming because it's often difficult to find a way out of it.


Why is it Important to Acknowledge Stress?

Stress should be accepted and dealt with because it can lead to physical, emotional and behavioural problems. It also has a negative effect on our productivity, decision making skills and relationships. Learning how to deal with stress in a healthy way is important for our overall well-being.


There are many different types of stress that we can experience in our lives. Some of them are caused by external factors, while others come from within ourselves. No matter where the stress comes from, though, it's important to learn how to deal with it in a healthy way so that it doesn't have a negative impact on our health and well-being. If we don't address the stress that we're feeling, it can lead to things like physical illness, emotional problems and behavioural issues. So, it's important to be proactive about stress and understand how to manage it in a healthy way.


One of the best ways to deal with stress is to acknowledge that it's there. This means recognizing when we're feeling stressed out and understanding why it's happening. Once we know what's causing our stress, we can start working on ways to address it. Just acknowledging the fact that you're feeling stressed out can be helpful because it allows you to start taking steps towards dealing with the problem. If we ignore the stress that we're feeling, it will only get worse over time. So, by being proactive and addressing the issue head-on, we can reduce impact on our lives.

FAQs on Causes of Stress

1. What is stress from a biological perspective?

From a biological standpoint, stress is the body's physiological and hormonal response to any perceived threat or challenge, known as a stressor. When a threat is detected, the nervous system triggers a 'fight or flight' response, leading to the release of key hormones like adrenaline and cortisol. These hormones prepare the body for immediate action by increasing heart rate, blood pressure, and energy supply.

2. What are the main categories of stressors that cause a stress response?

Stressors, the triggers of stress, can be broadly classified into several categories based on their origin. The main types include:

  • Physical Stressors: These are caused by physical demands on the body, such as extreme temperatures, illness, injury, or strenuous exercise.
  • Psychological Stressors: These originate from our thoughts and emotions, including exam pressure, anxiety, grief, low self-esteem, or fear.
  • Social Stressors: These arise from interactions with others, such as peer pressure, relationship conflicts, or social isolation.
  • Environmental Stressors: These are factors in our surroundings that cause stress, like excessive noise, pollution, traffic, or overcrowding.

3. How does chronic stress affect the human body over time?

Unlike short-term acute stress, chronic stress involves a prolonged activation of the stress response system. This sustained exposure to stress hormones like cortisol can have significant negative effects on the body. It can weaken the immune system, making a person more susceptible to infections. It also contributes to long-term health problems such as high blood pressure, heart disease, digestive issues, and metabolic changes.

4. How does the body's 'fight or flight' response work when a stressor is encountered?

The 'fight or flight' response is an automatic physiological reaction managed by the sympathetic nervous system. When the brain perceives a stressor, it signals the adrenal glands to release adrenaline and noradrenaline. This causes an immediate surge in heart rate and blood pressure, mobilises glucose for energy, and sharpens the senses. Shortly after, the hypothalamus-pituitary-adrenal (HPA) axis is activated, releasing cortisol to sustain the body's readiness to cope with the threat.

5. What is the difference between acute and chronic stress in terms of physiological impact?

The primary difference lies in duration and recovery. Acute stress is a short-term response to an immediate threat, after which the body quickly returns to a state of balance (homeostasis). Its physiological impact is temporary. In contrast, chronic stress is a long-term, persistent state of arousal. This prevents the body from returning to homeostasis, leading to constant high levels of stress hormones, which cause 'wear and tear' on bodily systems and deplete energy reserves.

6. What are some common biological and environmental stressors for a student preparing for exams?

A student preparing for exams faces a unique combination of stressors. Key examples include:

  • Biological Stressors: Irregular sleep cycles disrupting the circadian rhythm, poor nutrition from skipping meals, and physical fatigue from long hours of sitting.
  • Environmental Stressors: A noisy home environment, lack of a dedicated study space, or uncomfortable study conditions (e.g., poor lighting or temperature).
  • Psychological Stressors: The most significant is academic pressure, fear of failure, and competition with peers, which directly trigger the body's stress response.

7. Why can psychological stress, like exam pressure, cause physical symptoms like headaches or indigestion?

The mind and body are intrinsically linked. Psychological stressors like exam pressure activate the same 'fight or flight' pathway as a physical threat. The brain signals the release of stress hormones, which have body-wide effects. For instance, these hormones can cause muscles in the neck and scalp to tense up, leading to tension headaches. They also divert blood flow away from the digestive system to prioritise muscles and the brain, which can slow down digestion and cause symptoms like stomach aches or indigestion. This shows the body reacting physically to a perceived mental threat.

8. What are the key physiological signs that indicate the body is under significant stress?

When the body is under significant stress, it exhibits several tell-tale physiological signs. These are direct results of the hormonal and nervous system responses. Key signs include:

  • Elevated heart rate and blood pressure.
  • Persistent muscle tension, particularly in the shoulders, neck, and jaw.
  • Frequent headaches or migraines.
  • Gastrointestinal problems, such as stomach cramps, diarrhoea, or constipation.
  • A weakened immune response, leading to more frequent colds and infections.
  • Disrupted sleep patterns, like insomnia or excessive sleeping.
