1. Practise some form of physical fitnes routine - gym / running/ yoga / swimming/ any sport - what ever suits your time and body type..
2. Balanced diet rich in fruits and vegetables and adequate vitamins . High amount of
Vitamin C containing fruits should be taken.
3. Learn to De-stress - mental /emotional exertion also undermines immunity.
Warm regards
