Pay close attention to your posture: how you hold your head, how you stand, sit, and lie in bed. Be especially kind to your overworked neck. For every inch you hold your head far forward, the weight of your head doubles! Poor posture and stress both tend to jut you head forward, and holding you head too far forward causes more stress. Is it any wonder your neck, shoulders, back and jaw hurt? Sit straight up and tall with your feet on the ground.
Think about how you move through space. Try not to lean; stay upright and balanced. Practice walking as if you are being held up by an imaginary string coming out of the top of your head. Walk and stand tall.
Throughout the day (set your watch, if it helps), consciously relax your muscles. Sit or lie comfortably, and beginning at one end of your body (say, your feet), systematically relax your muscles. Pay special attention to your neck, shoulders, and face. Then stand straight, lower your shoulders, open your mouth slightly, and let your face "hang" from your head without moving your head forward. (If you can't relax your facial muscles easily, try faking a smile-it takes far fewer muscles to smile than frown, and you'll look nicer, too!)
The best thing you could do for yourself is several times a day, take deep, slow breaths through your nose and exhale through your mouth. Breathe slowly; don't hyperventilate.
Gentle to moderate exercise-when started slowly and increased gradually-increases circulation, improves flexibility, releases pain-killing endorphins, and gives your tense muscles something to do with all that tension!
