The notion of boosting one's immune is a very applaudable step yet proves to be cumbersome for some reasons. The immune system requires coherence and balance in order to function properly because it is a SYSTEM. Hence, several activities and actions must be combined to achieve such results. Examples of such includes consuming balanced meals as well as fruits and vegetables regularly, exercising regularly to maintain a healthy weight and burn excess fats in the body, moderately taking in alcohol, avoiding smoking, and also practising good personal hygiene. If possible try to maintain a stress-free lifestyle.
