In today’s rapidly developing society, the pace of human life is accelerating. The increase in information flow, social pressure, economic difficulties, and responsibilities at work or study all affect the psychological and physiological state of a person. Therefore, stress has become one of the most significant factors threatening human health.

Stress is the body’s adaptive response to external or internal stimuli. While short-term stress may serve as a protective mechanism, chronic or long-lasting stress can cause serious harm to health.

According to the World Health Organization (WHO), one in three people worldwide suffers from stress-related conditions, which contributes to the growing prevalence of cardiovascular, nervous system, and immune system diseases. Hence, studying stress, understanding its impact on the human body, and developing effective prevention methods are among the most pressing issues of modern medicine and psychology.

The Nature and Types of Stress

The term “stress” was first introduced by Canadian scientist Hans Selye in 1936. He defined it as the body’s nonspecific response to any external or internal pressure. Selye classified stress into two main types: eustress (positive stress) and distress (negative stress).

Eustress encourages activity, enhances productivity, and helps individuals adapt to challenges, whereas distress causes fatigue, mental exhaustion, and health deterioration.

Physiological Effects of Stress

During stress, hormones such as adrenaline, noradrenaline, and cortisol are released into the bloodstream. These hormones increase heart rate, elevate blood pressure, accelerate breathing, and tense muscles. While these changes are beneficial in the short term, chronic stress can lead to severe health problems, such as:

Cardiovascular diseases (hypertension, heart attack, stroke)

Stomach ulcers and gastritis

Decreased immune function

Endocrine disorders (diabetes, hormonal imbalance)

Sleep disturbances and chronic fatigue

Scientific research has shown that prolonged stress triggers inflammation at the cellular level and accelerates biological aging, weakening the body’s overall resistance.

Psychological Effects of Stress

Chronic stress significantly affects mental health. It disrupts concentration, reduces productivity, and worsens interpersonal relationships. Prolonged exposure to stress can lead to the following psychological conditions:

Depression and anxiety

Irritability and aggression

Social withdrawal and isolation

Loss of motivation

Sleep disorders

Moreover, neuroscientific studies indicate that long-term stress damages neural connections in the brain, impairing memory and cognitive abilities.

Causes of Stress

Stress may arise from both external and internal factors.

External factors: workplace pressure, social environment, financial problems, academic overload, and family conflicts.

Internal factors: low self-esteem, pessimistic thinking, lack of emotional stability, and an unhealthy lifestyle.

The combination of these factors places the body under constant tension, disrupting physiological balance and psychological well-being.

Methods to Reduce and Manage Stress

Effective stress management requires medical, psychological, and social approaches. The following are the most effective methods:

1. a) Maintaining emotional balance:

Meditation, deep breathing exercises, positive thinking, and relaxation techniques reduce anxiety and promote calmness. Practicing 10–15 minutes of controlled breathing daily helps stabilize the nervous system.

1. b) Physical activity:

Exercise is one of the most natural ways to reduce stress. Sports, walking, yoga, swimming, and dancing help lower stress hormones and boost endorphins, the “happiness hormones.”

1. c) Proper nutrition:

A diet rich in vitamins and minerals is crucial. B-group vitamins, magnesium, and omega-3 fatty acids play a vital role in maintaining nervous system health.

1. d) Sleep hygiene:

Adequate and quality sleep (7–8 hours per night) is essential for mental recovery. Sleep deprivation increases cortisol levels, aggravating stress symptoms.

1. e) Social support:

Positive communication with family and friends strengthens emotional resilience. People with strong social connections tend to cope with stress more effectively.

1. f) Medical and psychological assistance:

In some cases, stress management may require psychotherapy, counseling, or medical intervention. Professional guidance helps individuals develop coping strategies and emotional stability.

Preventive Measures Against Stress

Preventing stress is more effective than treating its consequences. Key preventive strategies include:

Maintaining a balanced daily routine

Ensuring proper work-rest balance

Allocating time for hobbies and leisure

Creating a positive and supportive environment

Strengthening emotional intelligence and self-awareness

Developing these habits helps individuals enhance stress tolerance and maintain long-term health.

Conclusion

Stress is an inevitable part of human life, yet the ability to manage it is a crucial determinant of overall health and well-being. Proper stress management improves cardiovascular, nervous, and immune system functioning, restores emotional balance, and enhances life quality.

The main components of stress reduction include healthy nutrition, physical activity, adequate sleep, positive thinking, and strong social connections. Recognizing stress as a natural physiological response and learning to control it enables individuals to live healthier, happier, and more productive lives.
