Lifestyle is very important.  Sleep by 10:00 P.M. in Traditional Chinese Medicine, 11:00 P.M. to 1:00 A.M. is when the Yin shifts to Yang.  It is crucial for the body to be at rest during this time for optimal health.  There is no better way to restore or enhance the immune system other than resting and sleeping before 10:00 P.M. Adequate sleep (at least eight hours) are essential to maintaining a strong immune system.

Avoid over-exertion both mentally and physically, either of which can suppress the immune system.

Wear appropriate clothing on cold, damp, windy days, and avoid becoming chilled or over-heated.

Patients are recommended to have a good balance between exercise, healthy diet, rest, and relaxation.  "
