Here are some things to try. Get Active .
Physical activity can relieve tension and stress-related fatigue.
Many people think if they can t get to the gym, they can t get a workout, says Emily Wark, a certified personal trainer in Seattle. Take a 10-minute walk at lunch with a friend, or do stretching exercises at your desk. Neck, upper back, and shoulder stretches are especially important, because they are tension-hugging areas. Fatigue is one sign of dehydration. Experts recommend that you drink at least 8 8-oz glasses of water everyday, more when you exercise heavily in hot weather.
