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

Stress can have profound emotional effects on an individual. For instance, when someone is under stress, they might find themselves feeling anxious or depressed. This is because stress can disrupt their emotional balance, causing fluctuations in their mood. If these feelings are not managed, they can lead to a decrease in confidence, which can, in turn, lead to more severe emotional issues. Stress affects not just the person experiencing it, but also their relationships, as erratic behavior might create distances with family and friends.

Imagine a student preparing for exams. As the stress builds, they may become irritable, snapping at friends and family due to their mounting anxiety. Over time, they might start to avoid social interactions because they feel overwhelmed and worry that they aren't good enough. This cycle of isolation and anxiety can snowball, leading to feelings of depression if they don't seek support or find ways to manage their stress effectively.

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. Although this physical reaction will help us to function more effectively when we are under pressure for short periods of time, it can be extremely damaging to the body in the long-term effects.

Stress triggers the body's fight-or-flight response, which is an automatic reaction to perceived threats. Hormones like adrenaline increase heart rate and blood pressure, preparing the body for quick action. While this mechanism can be beneficial in short bursts, chronic stress leads to constant high levels of these hormones, causing wear and tear on the body. Over time, long-term exposure to high stress can result in serious health issues such as heart disease, obesity, and diabetes.

Consider someone who works in a high-pressure job. If they're constantly racing to meet deadlines, their body may produce high levels of cortisol. Initially, this helps them meet their work demands. However, over months or years, the continuous high stress can lead to health issues like high blood pressure or heart problems. This is similar to a car running on high RPMs for too long without cooling down—eventually, the car's engine will overheat and break down.

If pressures due to stress continue, one may suffer from mental overload. This suffering from high levels 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. Cognitive effects of stress are poor concentration, and reduced short-term memory capacity.

Chronic stress can significantly impair cognitive functions. When a person is under continuous pressure, their cognitive resources become overloaded, resulting in poor decision-making and reduced concentration. Stress can cloud judgment, leading to hasty or faulty decisions that can affect work and personal life negatively. Additionally, stress can affect memory, making it harder to recall important information—a situation many students face during exam time.

Think of a busy manager juggling multiple projects with tight deadlines. The stress may lead them to forget key details in a meeting or overlook crucial tasks, resulting in missed deadlines or poor project outcomes. This situation resembles trying to juggle too many balls at once—eventually, some will drop, and managing fewer tasks properly often yields better results than trying to do everything poorly.

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 such as tranquillizers. Some of the typical behavioural effects of stress seen are disrupted sleep patterns, increased absenteeism, and reduced work performance.

Stress can lead to unhealthy behaviour patterns. Often, people under stress might resort to comfort eating, consuming more fast food, or drinking caffeine to cope with fatigue. These choices can disrupt normal routines, leading to poor health outcomes over time. Additionally, they might experience sleep disturbances which further exacerbate stress and negatively affect their overall performance in work and life.

Imagine a college student facing midterms. They might start skipping meals, relying on caffeine to stay awake and stress-eating junk food for comfort. Their sleep schedule could begin to suffer, resulting in fatigue and worse performance. This pattern can become a vicious cycle—stress leads to unhealthy choices, which in turn leads to poorer health and increased stress.
