Increase the mobility of your neck and entire spine to reduce stress

Lie comfortably on your back, weave the fingers of one hand together with the fingers of the other hand.

Put your hands behind the back of your head, with the weight of your head resting comfortably on your interwoven fingers.
You should feel the hardness of your cranium with your fingers, and you should feel the bones of your fingers on the back of your head. If you have a stiff shoulder and cannot bring both of your hands up behind the back of your head, it is sufficient to use one hand, with the fingers and palm contacting both sides of the back of your head.

Keeping your head in place, look to the right, moving only your eyes as far as you comfortably can.
Do not turn your head; just move your eyes. Keep looking to the right.

After a short period of time—up to thirty or even sixty seconds—you will swallow, yawn, or sigh.
This is a sign of relaxation in your autonomic nervous system.

Bring your eyes back to looking straight ahead.

Leave your hands in place, and keep your head still. This time, move your eyes to the left.

Hold your eyes there until you sigh, yawn, or swallow.
