Understanding Stress: What It Is and How It Affects Us
Discover the Science Behind Stress and Learn Effective Ways to Manage It
Stress: Definition and Science
Stress is our body’s natural response to pressures from situations or life events. While everyone experiences stress differently, it often arises from situations that feel new, unexpected, threatening, or beyond our control. In this article, we’ll explore the science behind stress and its three main pillars: psychological, pathological, and physiological.
Types of Stress: Positive and Negative
Not all stress is harmful. Positive stress, also known as eustress, can be motivating and help us perform at our best. It encourages us to meet challenges and achieve our goals. On the other hand, negative stress occurs when pressure becomes excessive, leading to physical or mental health issues. Understanding how to manage these different types of stress is key to maintaining well-being.
Fight or Flight: The Body’s Response to Stress
Our body’s response to stress is often known as the “Fight or Flight” response. During a stressful situation, your brain triggers your adrenal glands to release hormones like adrenaline and cortisol. These hormones prepare your body to either confront the threat or escape it by redirecting blood to your muscles, increasing your heart rate, and other physiological changes.

The Three Pillars of Stress
There are three types of stress that contribute to overall stress levels:
- Psychological Stress: This is stress that affects our mental well-being. It can stem from:
- Family and work pressures
- Financial strain
- Health problems
- Moving to a new location or traumatic incidents
- Pathological Stress: This involves internal bodily dysfunctions, such as issues with:
- Gut function
- Hormone balance
- Metabolism
- Menstrual cycle
- Physiological Stress: Physical strain on the body caused by:
- Sports
- Exercise
- Manual labor
How the Nervous System Handles Stress
The body’s response to stress involves two main branches of the autonomic nervous system:
- Sympathetic Nervous System (Fight or Flight): This is activated during times of stress, leading to effects like increased heart rate, lung dilation, and reduced digestion.
- Parasympathetic Nervous System (Rest and Digest): After the stressor has passed, the body shifts to this state, focusing on recovery by stimulating digestion, decreasing heart rate, and restoring balance.
Why Chronic Stress Is Harmful
Modern lifestyles often cause prolonged activation of the sympathetic nervous system, keeping cortisol levels elevated. This chronic stress state can lead to serious health issues such as:
- High blood pressure
- Weight gain
- Fatigue
- Mental health issues like anxiety
- Cardiovascular diseases
Takeaway: Managing Stress for Better Health
To manage stress effectively, it’s essential to implement relaxation techniques that promote a shift to the parasympathetic state. Activities like deep breathing, meditation, and regular physical exercise can help reduce stress and prevent the health complications associated with chronic cortisol elevation.
