Emotions are closely linked to health, and changes in mood can directly impact one's health. In particular, prolonged negative emotions can lead to various health conditions.
Long-term, high levels of psychological stress may cause or exacerbate these health problems.

- Cardiovascular disease:
Studies have shown that psychological stress can increase the risk of heart disease and stroke. Sustained stress can increase heart rate and blood pressure, and long-term accumulation can lead to cardiovascular problems such as arteriosclerosis.
- Depression and anxiety:
Stress is a major contributing factor to depression and anxiety. Chronic stress can alter chemical signaling in the brain, triggering depressive symptoms such as low mood and hopelessness. It can also significantly increase anxiety levels.
- Digestive disorders:
Stress increases gastric acid production, which can lead to digestive disorders such as gastric ulcers, gastroesophageal reflux disease, and irritable bowel syndrome.
- Immune System Dysfunction:
Individuals experiencing chronic stress may experience a weakened immune system, making them more susceptible to illness and prolonging recovery time.
- Sleep Disorders:
Stress often leads to insomnia or poor sleep quality, which further impacts overall health.
Sustained high levels of psychological stress can negatively impact physical health. Active measures should be taken to manage and alleviate stress to prevent related illnesses.
