Today, we’re delving into what stress really means. Stress can arise from many sources, like major life events or even daily hassles. Who can name some examples of stressors from your own experiences?
Exams can be stressful!
A breakup with a friend is also very stressful.
Great examples! Stressors like exams and relationships highlight that stress is not just situational but a response that varies per individual. Let’s remember, stress can be associated with both positive and negative experiences.
What’s the difference between positive and negative stress?
Positive stress can motivate us, termed 'eustress', while negative stress, or 'distress', can lead to feelings of overwhelm. Thus, perception plays a key role in how we experience stress.

Now, let’s discuss what happens to our bodies when we are under stress. Can anyone guess what physiological changes occur?
Our heart rate increases, right?
Exactly! When stressed, cortisol and adrenaline are released, which can lead to increased heart rate and blood pressure—part of what we call the 'fight or flight' response.
What are the long-term effects of this?
Good question! Prolonged stress can lead to chronic illnesses, such as heart disease or weakened immune response. This illustrates why managing stress is crucial for maintaining health.
Coping Strategies

Having understood the effects of stress, let’s shift our focus to coping strategies. Can anyone share techniques they use to manage stress?
I try to exercise or go for runs when I feel stressed.
I like to talk to a friend or family member.
Those are excellent methods! Exercise is a great way to process stress physically, and social support can help alleviate feelings of anxiety. Remember—finding effective coping strategies can often mitigate the negative effects of stress.
General Adaptation Syndrome

Let’s now examine Hans Selye’s General Adaptation Syndrome, or GAS. It describes the three stages of stress response. Who can name them?
There's the alarm stage!
And resistance!
Finally, exhaustion, right?
Correct! The alarm stage prepares the body for a response, resistance signifies coping with the stressor, and exhaustion reveals how prolonged stress can wear down our capabilities. What might be a consequence of reaching exhaustion?
It could lead to serious health issues.
Exactly! Therefore, it's important to monitor stress levels and employ coping strategies before reaching that point.
Stress and Immune System

Lastly, I want to highlight the relationship between stress and our immune system. How does stress impact our health?
Stress can make us sick, right?
Yes! Stress can weaken our immune response, making us more susceptible to illness. Can anyone think of a situation where this happened?
Well, I’ve noticed I get sick more often during exam season.
That’s a perfect example! It underscores the importance of managing stress through healthy lifestyles and coping techniques to maintain our overall health.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The section elaborates on stress as a complex response to life challenges, characterizing its types, sources, and various physiological effects on health. It further emphasizes the significance of coping methods and the role of stress in psychological functioning.
Detailed
Physiological Effects of Stress
The physiological effects of stress encompass a range of responses that occur when an individual faces challenges or engages with stressors in their environment. Stress is neither purely situational nor solely an internal reaction; rather, it is a continuous transactional process between individual perception and external pressures.
Nature and Sources of Stress
Stress originates from various sources, including major life changes, daily hassles, trauma, and social interactions. Hans Selye posited the 'General Adaptation Syndrome' (GAS), outlining three stages of stress response: alarm, resistance, and exhaustion, which illustrates how prolonged stress affects the physical and mental state of individuals. Stress prompts physiological reactions that can lead to symptoms like heightened heart rate, altered glucose metabolism, increased blood pressure, and even immune dysfunction.
Effects on Psychological Functioning
Physiologically, stress can lead to emotional disturbances such as anxiety, mood swings, and depression, which in turn can impact physical health adversely. Chronic stress is linked with numerous long-term health issues, such as cardiovascular disease and psychosomatic disorders. Thus, understanding both the physiological and psychological dimensions of stress is essential for developing effective coping strategies, ultimately leading to improved health and well-being.

Chapter Content
What are the effects of stress? Many of the effects are physiological in nature, however, other changes also occur inside stressed individuals. There are four major effects of stress associated with the stressed state, viz. emotional, physiological, cognitive, and behavioural.
Detailed Explanation
Stress has widespread effects on our body and mind, which are categorized into four main areas: emotional, physiological, cognitive, and behavioral. Emotional effects include mood swings and anxiety. Physiological effects relate to changes in bodily functions, like increased heart rate. Cognitive effects affect our thinking, leading to poor decision-making. Behavioral effects may involve changes in habits, such as eating less or using unhealthy substances.
Examples & Analogies
Imagine a student preparing for a big exam. Stress may make them anxious (emotional effect), cause their heart to race (physiological effect), lead to trouble focusing and remembering study material (cognitive effect), and prompt them to skip meals or rely on caffeine (behavioral effect).

Emotional Effects: Those who suffer from stress are far more likely to experience mood swings, and show erratic behaviour that may alienate them from family and friends. In some cases this can start a vicious circle of decreasing confidence, leading to more serious emotional problems.
Detailed Explanation
Stress can greatly influence our emotions. Individuals under stress often experience heightened feelings of anxiety and irritability, which can lead to mood swings. These emotional disruptions can create problems in relationships, as loved ones may struggle to understand the changes in behavior. Over time, this can harm one's self-esteem and mental health, leading to isolation.
Examples & Analogies
Consider a teenager who is stressed about school. They might become irritable and lash out at friends or family, resulting in arguments and a sense of loneliness. This emotional cycle can further intensify their anxiety about school, creating a loop of stress and negative feelings.

Physiological Effects: When the human body is placed under physical or psychological stress, it increases the production of certain hormones, such as adrenaline and cortisol. These hormones will produce marked changes in heart rate, blood pressure levels, metabolism and physical activity.
Detailed Explanation
Stress triggers the release of hormones that prepare the body for a 'fight or flight' response. For instance, adrenaline increases heart rate and blood flow, while cortisol manages energy supply. While these responses can be helpful in acute situations, long-term stress can lead to health issues like hypertension and heart diseases.
Examples & Analogies
Think of stress as having an emergency alarm that signals your body to be ready. Imagine you're hiking and suddenly see a snake; adrenaline surges through you, making your heart race and muscles tense to react quickly. However, if this alarm keeps going off daily due to work stress, it can take a toll on your health, much like a smoke alarm that gets faulty and rings for no reason.
Cognitive Effects of Stress

Chapter Content
Cognitive Effects: If pressures due to stress continue, one may suffer from mental overload. This suffering from high-level stress can rapidly cause individuals to lose their ability to make sound decisions.
Detailed Explanation
High stress can cloud our thinking and deplete cognitive functions. People might find it difficult to concentrate or remember things, leading to poor decision-making. This cognitive strain occurs because the brain is overwhelmed, diverting resources toward handling stress rather than focusing on tasks.
Examples & Analogies
Imagine you're trying to study for a test while your phone keeps buzzing with notifications. The noise and stress of not understanding the material can lead you to feel confused and unable to recall information during the exam, similar to being in a noisy room trying to hold a conversation.
Behavioral Effects of Stress

Chapter Content
Behavioural Effects: Stress affects our behaviour in the form of eating less nutritional food, increasing intake of stimulants such as caffeine, excessive consumption of cigarettes, alcohol and other drugs.
Detailed Explanation
Behavioral responses to stress can manifest as unhealthy lifestyle choices. When stressed, individuals might turn to junk food, caffeine for energy, or substances like alcohol to cope. These habits might provide temporary relief but can worsen health problems in the long run.
Examples & Analogies
Picture someone at work who feels overwhelmed by deadlines. They might skip lunch in favor of an energy drink to stay awake, or grab comfort food like chips during breaks. While it helps temporarily, these choices can lead to fatigue, weight gain, and even chronic health issues.

Chapter Content
The physiological effects of stress can lead to exhaustion and greater vulnerability to diseases. Researchers estimate that stress plays a significant role in physical illnesses and that many medical visits are for stress-related symptoms.
Detailed Explanation
Stress not only affects how we feel but can also make us physically ill. Through various physiological changes, our body becomes less equipped to handle infections and manages energy poorly. This connection explains why chronic stress is linked to a plethora of health issues and why it's important to address stress immediately.
Examples & Analogies
Consider a worker dealing with constant stress at their job and neglecting their health. Over time, this stress could contribute to them falling ill frequently, possibly with colds or more serious illnesses, much like a car that runs poorly if not properly maintained.
