But stress isn't necessarily the cause of these pains. In fact, tension headaches got their name from muscular tension - like when you clench your jaw when you're late for an appointment. Tension in one part of the body tends to spread. So, make sure you're using the right equipment to maintain good posture and avoid the stress of repeated motion and awkward positions. Exercise, of course.
Nothing relaxes the body more than exercise.
It's best to exercise regularly three or four times a week. Mind over aches. Relax the mind so the body will follow. Take a few deep breaths and relax your jaw. Treat yourself to massage therapy, which not only relaxes muscles but also relieves stress.
