If you're experiencing physical problems as a result of job stress, take advantage of every opportunity to relax. If you're used to exercising regularly, carve out time to stick to your regimen. Many people find that even just a 20-minute walk or jog can clear their heads and rejuvenate their energy. Perhaps most important, try to get enough sleep. Fatigue is notorious for making even the most minor problem look far worse than it really is.
