3.3.4. Behavioural Effects

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 behavioral.

Stress has a range of effects on individuals. It can cause emotional changes, which often include mood swings and erratic behavior. Physiologically, stress triggers the release of certain hormones that can affect body functions like heart rate and blood pressure. Cognitively, stress can overload a person’s mental capacities, leading to poor decision-making and reduced concentration. Behaviorally, it might manifest as changes in eating habits, sleep patterns, and general work performance.

Imagine preparing for a big presentation at work. The stress leads to feelings of anxiety (emotional effect), you might experience a rapid heartbeat (physiological effect), find it hard to focus on your slides (cognitive effect), and even skip meals due to nervousness (behavioral effect). All these illustrate how stress can disrupt your day-to-day life.

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. Some examples are feelings of anxiety and depression, increased physical tension, increased psychological tension and mood swings.

Emotional effects of stress can lead to significant changes in how individuals interact with others. Mood swings caused by stress might make someone irritable or withdrawn, leading to conflicts or isolation. Anxiety and depression are common responses, causing individuals to feel overwhelmed and less connected to their social circles.

Consider a student who is stressed about exams. They might snap at friends, feel anxious and unable to join group study sessions due to their overwhelming feelings of inadequacy. This behavior not only impacts their own mental health but can also create distance in friendships.

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 can lead to changes in heart rate, blood pressure levels, and physical activity.

Physiological responses to stress can significantly alter how our body functions. The hormones released during stress can prepare the body for rapid responses but if stress is persistent, it can lead to chronic health issues such as hypertension or heart disease. The body’s systems, such as metabolism and immune function, can also be affected, making one more susceptible to illnesses.

Think about how you feel during a job interview. Your heart races (increased heart rate), your palms might sweat (physical signs of stress), and after the interview, you may feel exhausted. If such stressful situations occur frequently, your body may start exhibiting signs of long-term stress.

If pressures due to stress continue, one may suffer from mental overload. High levels of stress can rapidly cause individuals to lose their ability to make sound decisions. Cognitive effects of stress include poor concentration, and reduced short-term memory capacity.

Cognitive effects refer to how stress impacts our thinking processes. When individuals are stressed, their ability to concentrate diminishes. They may struggle with decision-making and remembering details, leading them to make mistakes or overlook important information, which can further exacerbate stress.

Picture a college student balancing multiple assignments and exams. The stress of looming deadlines makes it hard for them to focus on studying, leading to missed details in their notes or incorrect answers on exams. This cycle can make them more distressed about their academic performance.

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. Typical behavioural effects of stress seen are disrupted sleep patterns, increased absenteeism, and reduced work performance.

The way individuals behave when stressed can lead to unhealthy habits. Stress can trigger people to turn to comfort foods or stimulants as coping mechanisms, which can be detrimental in the long run. Other behaviors might include social withdrawal, poor work performance, or taking more sick days due to stress-related issues.

Imagine someone going through a rough patch at work. They might skip healthy meals, use caffeine to get through the day, and even find themselves reaching for alcohol to unwind at night. Over time, such behaviors can compound stress and lead to health challenges.
