Features of Stress – MCAT Content

You are standing at the edge of a cliff, looking down into a deep canyon. Your heart racing, your palms getting sweaty, and your mind whirlling with thoughts. This intense reaction is your bodyโ€™s natural response to a perceived threat, commonly known as stress.

All of us experience stress at some point in our lives. Whether you are preparing for an important exam, dealing with a difficult relationship, or facing a tight deadline at work, stress triggers a series of reactions in your body. 

These reactions can be physical, like a racing heart. They can also be emotional, like feelings of anxiety, or behavioral, like irritability.

Understanding stress helps us manage it better and stay healthy. Letโ€™s explore the main features of stress and how we can deal with it effectively.

I. Understanding Stress

Stress is our body's response to any demand or threat. When you sense real or imagined danger, your bodyโ€™s defenses kick into high gear. This is known as the "fight-or-flight" reaction or the stress response.

Stress Response

The stress response is your bodyโ€™s way of protecting you. Working properly helps you stay focused, energetic, and alert. In emergencies, stress can save your life. For instance, the stress response can make you slam on the car brakes to avoid an accident.

However, beyond a certain point, stress stops being helpful. It may cause major damage to your health, mood, productivity, relationships, and quality of life.

Symptoms of Stress

Stress affects all aspects of our lives. This includes your emotions, behaviors, thinking ability, and physical health. No part of the body is immune. People handle stress differently, so symptoms can vary.

Symptoms Of Stress
Common Physical Symptoms:
  • Headaches
  • Muscle tension or pain
  • Chest pain
  • Fatigue
  • Change in sex drive
  • Stomach upset
  • Sleep problems
Common Emotional Symptoms:
  • Anxiety
  • Restlessness
  • Lack of motivation or focus
  • Feeling overwhelmed

II. Types of Stress

Types Of Stress

There are several types of stress. Each has different characteristics and effects.

Acute Stress

The most common type of stress comes from the demands and pressures of our recent past. It also arises from anticipated demands and pressures of the near future. This type of stress is familiar to many because it happens often in daily life.

Acute stress is thrilling and exciting in moderation. However, it becomes exhausting when itโ€™s too much. Examples include a job interview or a near miss in traffic.

Episodic Acute Stress

People who frequently experience acute stress have episodic acute stress. Their lives present frequent triggers of stress. 

They are always in a rush, always late, and if something can go wrong, it does. Over time, this can cause long-term health problems such as high blood pressure or heart disease.

Chronic Stress

This type of stress wears people away day after day, year after year. Chronic stress destroys bodies, minds, and lives. 

It wreaks havoc through long-term attrition. Examples of chronic stress include ongoing poverty, an unhappy marriage, or a toxic work environment.

III. Causes of Stress

Feeling stressed is a natural part of life. Many events around you and things you do can cause your body to feel stressed. You can feel stress from your surroundings, body, and thoughts.

Environmental Stressors:
  • Major life changes
  • Work or school
  • Relationship difficulties
  • Financial problems
  • Being too busy
  • Children and family
Body Stressors:
  • Health issues
  • Lack of sleep
  • Poor nutrition
  • Physical injury

Thoughts Stressors:
  • Negative self-talk
  • Unrealistic expectations
  • Perfectionism
  • Pessimism

IV. Coping with Stress

Stress management is about taking charge of your thoughts, emotions, schedule, and environment and dealing with problems. Here are some ways to cope with stress:

Coping With Stress

Physical Activities

Physical activities can help reduce stress. Activities like walking, running, or yoga are beneficial. 

Exercise increases the production of endorphins. These are chemicals in the brain that serves as natural painkillers and mood elevators.

Relaxation Techniques

Practicing relaxation techniques can help activate your bodyโ€™s relaxation response. This state of restfulness is the opposite of the stress response. Techniques like deep breathing, meditation, or progressive muscle relaxation are effective. 

  • Deep breathing means taking slow, deep breaths to help calm your body. 
  • Meditation means concentrating your mind to reach a relaxed state.
  • Progressive muscle relaxation involves tightening and then slowly relaxing each muscle group.

Social Support

Talking to others can provide comfort and stress relief. Sharing your feelings with friends, family, or counselors can help you feel supported and less alone. 

Social support systems work differently in various cultures. Family support is strong in some cultures, while in others, friends or community groups provide support.

Healthy Lifestyle Choices

Maintaining a healthy lifestyle can improve your ability to handle stress. This includes consuming a balanced diet, sleeping well, and avoiding excessive alcohol and caffeine. 

A balanced diet provides the essential nutrients to keep your body functioning well. Adequate sleep helps your body recover and manage stress. Limiting alcohol and caffeine can prevent additional stress.

IV. Bridge/Overlap

As mentioned above, understanding stress is crucial because it affects many areas of our lives. This topic also connects to other areas you might study.

Neuroendocrine System

Stress triggers the release of cortisol, a hormone the adrenal glands produce. Cortisol plays a significant role in the bodyโ€™s stress response and is part of the neuroendocrine system. This involves the interactions between the nervous system and the endocrine system.

Coping Mechanisms

Different coping mechanisms are used to manage stress and difficult emotions. Understanding these mechanisms can help develop effective strategies for handling stress and improving mental health.

Psychological Disorders

Stress is a major factor in the development and exacerbation of psychological disorders such as anxiety and depression. Learning about how stress interacts with these disorders can provide insights into better treatment and management approaches.
