Research shows that sleep-deprived people produce fewer virus-fighting cells. And it's normal to sleep a bit more in winter; before we had electricity, people went to bed earlier and slept longer as the days got shorter.

Your body has its own thermostat that regulates temperature -- that's what goose bumps do. Overheated houses and workplaces can make this internal thermostat "lazy" and less effective. To keep your internal heating system in good working order, take "contrast showers" -- hot water followed by a blast of cold. Try starting with 5 seconds of cold water and working up to 30 seconds.
Yoga's twists, backbends, and inversions stimulate important immunity components -- the adrenal glands and lymphatic system -- helping them perform better.

Try our immunity-boosting poses this season to help stave of the sniffles.
