How to Improve Human Immunity

1. Diet: Eat more fresh vegetables, fruits, and foods rich in vitamins; reduce intake of oil, salt, and pickled foods to maintain balanced nutrition in the body. 2. Exercise: Engage in regular physical activity, but avoid overexertion, as this can promote blood circulation and enhance the body's ability to effectively resist external pathogens. 3. Sleep: Pay attention to rest and ensure at least 8 hours of adequate sleep each day, as sleep quality directly affects the body's immune function. 4. Lifestyle habits: Quit smoking, limit alcohol consumption, spend more time in clean, fresh air environments, minimize exposure to toxic and harmful chemicals and radioactive substances, and maintain good personal hygiene practices. 5. Vaccination: Complete vaccinations on time to strengthen immunity.
