Can 20 minutes of exercise per day boost immunity?

Generally speaking, exercising for 20 minutes a day can boost immunity, but it's important not to overdo it. The detailed explanation is as follows:

Exercise promotes internal circulation and endocrine function, helping maintain optimal performance of the body's organs and effectively enhancing the body's immune system. Just 20 minutes of moderate exercise can stimulate the immune system, triggering anti-inflammatory cellular responses. By reducing inflammation, physical activity lowers the risk of illness and improves overall health. Exercise also helps reduce stress levels and enhances mental well-being. Chronic stress and anxiety can negatively affect the immune system, while regular physical activity is an effective way to relieve stress. When psychological stress is reduced, immune function improves accordingly. However, it's important to avoid excessive exercise, as overtraining may have adverse effects on the immune system, leading to fatigue, immune suppression, and hormonal imbalances.

When exercising, individuals should consider their physical condition and health status, avoiding overexertion. After exercise, attention should be paid to staying warm and allowing adequate rest to promote recovery. Additionally, maintaining a healthy diet and good sleep habits also positively contribute to boosting immunity.
