It weakens the immune system.

Explanation:

According to scientific studies, prolonged stress affects the immune system and makes the body more susceptible to disease.

Cortisol is a hormone that acts to inhibit the body's defense system and is related to cardiovascular complications. With constant stress, the body produces it in large quantities, causing the body itself to relax its defenses. The consequence is the poor response of the immune system that becomes weakened and makes the body highly susceptible to disease.

To reduce stress and increase body protection, psychotherapeutic help is needed to treat the problem and implement a number of changes in habits: Sleep well, avoid smoking, drinking alcohol, and eating well, and doing physical activity.
