What are the important reasons for decreased immunity?

Generally speaking, there is no specific list of "important reasons for decreased immunity." Immune system weakness may be related to factors such as nutritional imbalance, inadequate rest, high mental stress, lack of physical activity, and primary immunodeficiency disorders. If experiencing any discomfort, it is recommended to seek medical attention promptly. A detailed explanation is as follows:

1. Nutritional Imbalance

Irregular eating habits, picky eating, or insufficient food intake can lead to inadequate nutrition, thereby weakening the body's immune system. It is recommended to avoid overeating or excessive preference for certain foods and to ensure balanced nutrient intake.

2. Inadequate Rest

Insufficient sleep or poor sleep quality may reduce the body's antiviral capabilities and increase the risk of viral infections. It is recommended to maintain adequate sleep and avoid staying up late for prolonged periods.

3. High Mental Stress

Strong and prolonged negative emotions such as depression and anxiety may cause nervous system instability, which in turn affects immune function. It is advisable to relax appropriately, for example by listening to music or hiking.

4. Lack of Physical Activity

Exercise is an important way to enhance immunity. Lack of physical activity can lead to a decline in bodily functions, including the immune system. Sedentary lifestyles or prolonged bed rest can also reduce immunity. Engaging in appropriate physical activities such as running or jumping rope can help strengthen the immune system.

5. Primary Immunodeficiency Disorders

Primary immunodeficiency disorders may be associated with genetic factors or congenital developmental abnormalities. Symptoms may include weight loss, growth delays, and susceptibility to infections. Treatment under medical guidance with medications such as azathioprine tablets or deferasirox dispersible tablets may be considered.

It is recommended to maintain a balanced diet, avoid staying up late and overexertion, and engage in regular moderate exercise such as walking, jogging, or swimming.
