Dr JK Avhad MBBS MD [ Last updated 14.12.2025 ]

Globally, stress is one of the most widespread psychological and physiological conditions of modern life. It is estimated that more than 75–90% of primary care visits worldwide are related to stress associated complaints such as headache, insomnia, anxiety, digestive issues, high blood pressure, fatigue. In today’s fast paced world, characterized by work pressure, digital overload, financial uncertainties, relationship conflicts, and lifestyle imbalance, stress has emerged as a major public health concern.

This comprehensive guide explores what stress is, its biological mechanisms, types, signs and symptoms, risk factors, complications, diagnosis, and proven management strategies.

Understanding Stress: Definition and Conceptual Framework

What Is Stress?

Stress is the body’s physical, psychological, and emotional response to any perceived threat or challenge. This response is known as the stress response or fight or flight response. It prepares the body to react quickly, but when activated too often or for too long, it can harm nearly every system in the body.

The Stress Response System

Stress activates two major pathways:

Sympathetic System

  • Releases adrenaline and noradrenaline
  • Increases heart rate, blood pressure, breathing rate
  • Enhances alertness and energy supply

Hypothalamic-Pituitary-Adrenal (HPA) Axis

  • Releases cortisol (a stress hormone)
  • Regulates metabolism, inflammation, and immune response
  • Chronic activation leads to harmful health effects

 Eustress vs Distress

Not all stress is harmful.

Type of Stress

Description

Impact

Eustress (Positive Stress)

Short-term, motivating, improves performance

Drives creativity, learning, productivity

Distress (Negative Stress)

Prolonged, overwhelming, exhausting
