Rest, rest, rest
During a cold, the body needs rest more than it does activity. So, skip yoga your workouts, and other strenous physical activity. If possible, take the day off work at the onset of a cold. Allow your body focus on getting better. While this may seem ridiculous, it is possible to stop a cold dead in its tracks.
Do you think that it is impossible to catch a cold from cold? Sleeping in an overly air-conditioned room or going without a coat for too long in the winter is enough to make you sick. Wearing an undershirt that covers your chest (a main site of , which is out of balance during a cold) and layer with a warm sweater. Drying your hair after a shower or bath and always cover your head and body when going outside.
