Why is it rare for people to have completely normal results in physical examinations?

Very few people can achieve completely normal results in physical examinations. This may be due to various factors such as bad habits, psychological stress, and lack of exercise, all of which can affect physical health. However, with proper health management, good outcomes are generally achievable. The specific analysis is as follows:

1. Bad Habits

Nowadays, many people have unhealthy lifestyle habits, such as frequently staying up late, eating junk food, and drinking sugary beverages. These behaviors are highly detrimental to health and can easily lead to weakened immunity, malnutrition, and gastrointestinal diseases. Therefore, maintaining a regular daily routine and healthy eating habits is essential for preserving good health.

2. Psychological Stress

Many individuals today face prolonged pressure from life and work, resulting in significant psychological stress. This can easily cause autonomic nervous system dysfunction, leading to symptoms such as headaches, indigestion, and insomnia, all of which negatively impact physical health. It's important to manage mental well-being, maintain emotional stability, and balance work and rest appropriately to support overall health.

3. Lack of Exercise

Modern lifestyles often involve busy work and study schedules, leaving little time for physical activity. A long-term lack of exercise slows blood circulation and reduces immunity, increasing susceptibility to infections and illnesses such as colds and gastroenteritis, seriously endangering health. It's advisable to set aside time regularly for moderate exercise, which helps improve circulation and strengthen the body's resistance.

In addition, prolonged use of mobile phones and computers among modern populations causes significant eye strain. For these reasons, very few people achieve perfectly normal results during medical check-ups. Therefore, maintaining healthy lifestyle and dietary habits, along with a balanced approach to work and rest, is crucial for supporting good health.
