How to boost the immune system when it is weak

1. Eat more fresh vegetables and fruits rich in vitamins A and C, as well as minerals such as calcium, iron, and zinc, which help support the development and normal function of the immune system. 2. Consume more protein-rich foods, such as soy products, fish, and meat, which promote the development of immune cells and enhance the body's immunity. 3. Drink plenty of water and replenish fluids promptly to support normal immune system function and maintain cellular vitality and antiviral capacity. 4. Exercise regularly, as physical activity improves immune system function, increases the number of active white blood cells in the body, and boosts overall immunity. 5. Limit intake of greasy and high-calorie foods, as excessive consumption can lead to obesity and impair immune system function. 6. Minimize contact with others, especially those who are ill, to prevent infectious diseases and protect the normal function of your immune system. 7. Seek timely medical treatment; illnesses should be treated promptly without delay to prevent worsening conditions and damage to immune system function.
