Neck tension arising from long hours at the desk or behind the wheel of the car can be relieved by certain neck exercises.
These include rotating the head clockwise and anticlockwise, allowing the head to drop forward and backward as far as possible and turning the head to the right and left as far as possible several times. These exercises help to loosen up contracted neck muscles
which may restrict the blood supply to the head.
Neck tension may also be relieved by the yogic discipline pranayama, if the arms are held closely to the body through the exercise. Stand erect with the feet aligned straight and touching each other. Lock the fingers together with the hands beneath the chin and keep them there through the entire exercise.
Slowly raise the arms as you inhale, filling your lungs with air. Feel the action of the breathing through your throat. Then raise your arms above your head as you lean back and exhale, all the while keeping the hands at your chin. When you completely exhale, feeling the movement of the air through your throat, lower your arms and repeat the exercise 20 times.
