To enhance the body's immunity, the first step should be to strengthen overall health by maintaining a proper diet and engaging in appropriate exercise to keep the body in good physical condition. In addition, consuming adequate essential amino acids, minerals, and vitamins can also help boost the immune system. In particular, ample intake of vitamin C, vitamin E, and trace elements such as selenium has a significant promoting effect on immunity. Eating foods rich in various antioxidants can also help reduce the burden on the immune system and enhance the body’s immune function. Finally, getting sufficient rest, avoiding staying up late, and maintaining a positive mood are important for improving immunity.
