3.3.3. Cognitive Effects

If pressures due to stress continue, one may suffer from mental overload. This suffering from high level of stress can rapidly cause individuals to lose their ability to make sound decisions. Faulty decisions made at home, in career, or at workplace may lead to arguments, failure, financial loss or even loss of job.

When a person is under constant stress, their ability to think clearly and make good decisions can be compromised. This is known as mental overload. For example, if someone is worried about their exam results all the time, they might struggle to focus on studying effectively and could end up making poor choices about how to prepare, such as not studying at all or relying too heavily on last-minute cramming.

Imagine you are trying to make an important decision about what university to attend while juggling part-time work and family issues. The stress from these competing demands can cloud your judgment, making it difficult to choose the best option based solely on your academic goals.

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

Stress triggers a biological response in our bodies that involves the release of hormones like adrenaline and cortisol. This response elevates heart rate and blood pressure to prepare the body for 'fight or flight' situations. While this is useful in emergencies, prolonged exposure to such hormonal changes can be harmful.

Think of a car engine that revs up when you press the accelerator. If you keep pressing the accelerator without releasing it, the engine can overheat and suffer damage. Similarly, chronic stress keeps our bodies in a heightened state, which can lead to health problems like hypertension or fatigue.

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.

Constant stress can lead to emotional instability and mood changes. When people are stressed, they might react more strongly to situations, which can push their loved ones away. For instance, if someone is always on edge due to stress, they might snap at a friend for a minor annoyance, damaging personal relationships and leading to greater isolation.

Think of a balloon that is continually being filled with air. If it gets too full without any release, it will pop. Similarly, if people do not manage their stress, they might 'pop' emotionally, leading to outbursts or withdrawal from their social circles.

Cognitive effects of stress include poor concentration, and reduced short-term memory capacity. This can affect an individual's performance in various areas of life, including work and academic settings.

Prolonged stress can negatively affect various cognitive functions, such as memory and focus. For example, if a student is stressed about grades, they may find it difficult to remember study material or concentrate during lectures. This cognitive impairment can result in lower academic performance.

It’s like trying to use a computer that has too many applications running at once. The processing speed slows down, affecting your ability to complete tasks efficiently. In a similar manner, stress can overload your brain, hindering your focus and memory.

Behavioural effects of stress include disrupted sleep patterns, increased absenteeism, and reduced work performance. Stress affects our behaviour by pushing individuals to engage in unhealthy habits.

Stress can lead to changes in behavior such as insomnia, emotional eating, or withdrawal from social situations. Individuals may also be more prone to skipping work or school when feeling overwhelmed, affecting their overall performance and productivity.

Imagine someone who regularly exercises and eats well suddenly starts to feel overwhelmed at work. Instead of going for their usual run, they stay late at the office. Over time, this lack of healthy activity can further exacerbate feelings of stress, creating a cycle that negatively impacts their well-being.
