With cold and flu season at its peak, health experts say the best defense is a healthy diet, plenty of rest and moderate exercise. But during the holidays, many people find this formula nearly impossible.

Experts also say adequate sleep, exercise and minimal stress can promote wellness and even a faster recovery when ill.
