Stress has taken a toll on my body, and have symptoms of low immunity (chronic inflammation issues), at 27 yrs old. plan to improve lifestyle. how can i improve my immune system? regular exercise, healthy eating, sleep? anything else?

Don’t overthink this: In spite of what you see in some media, there is virtually nothing you can do to “improve your immune system”. Don’t smoke, eat a balanced diet, and get some exercise regularly. Unless you have HIV, profound malnutrition, or a rare generic disease, lifestyle has almost no impact on your immune system. Supplement companies and some ‘alternative practiioners’ would love for you to believe otherwise
