What are the reasons for decreased immunity

A decline in human immunity can lead to the breeding of some diseases. This is the body's defense mechanism, and the reasons for a decline in human immunity are also multifaceted. Many factors definitely lead to decreased immunity, so improvements also need to be targeted at the causes.

1. Nervous emotions

A tense and uneasy mentality will have adverse effects on the autonomic nervous system, and the autonomic nervous system and endocrine system are closely connected.

2. Physical fatigue

Long-term lack of sleep and physical fatigue will increase the burden on the autonomic nervous system, and will also have a certain impact on the endocrine system and immunity, causing a decrease in immunity.

3. Negative and pessimistic

In life, excessive negativity and pessimism can lead to a decrease in immunity, so it is very important to keep a happy mood.

4. Unbalanced diet

Being picky about food and irregular meal times can lead to nutritional imbalance in the body's immunity.

5. Not enough exercise

Lack of exercise will lead to a decrease in physical strength. If the physical strength cannot keep up, it will be easy to get tired, which will gradually lead to a decrease in the body's resistance. This is the cause of low immunity that needs our most attention.

6. Excessive use of antibiotics

Nowadays, society can provide people with very good antibacterial drugs. However, do not over-clean and care for the skin. If the body's immunity is over-cleaned, it will lead to a decrease in body resistance.

7. Physical aging

As we age, we begin to recover more slowly from illness or become more susceptible to colds because our immune systems age and do not function as effectively.
