Many faced the unpleasant sensation of achingpain in the hand that can wake up at night. Attempts to move a limb result in failure, only after a few minutes a slight tingling appears in the fingers, which eventually grows. Then it gradually subsides, but the feeling of discomfort persists for some time. Such feelings indicate that your right arm grows from elbow to hand (or left). Numbness is an unpleasant, but quite often occurring phenomenon.
Why are your hands dumb?
The most common cause of numbness in the hands -this is an incorrectly chosen pillow for sleeping. Too much force the sleeper to strongly bend the cervical spine, which leads to a disruption in the circulation and, consequently, to impaired mobility and sensitivity of the upper limbs. So if your right arm is numb from the elbow to the hand or left, listen carefully to your sensations before going to sleep - whether it's convenient for you to lie on your pillow. Too small a pillow can lead to the same consequences, so it's best to get a suitable orthopedic and forget about the problems with your hands.
If your hands grow numb before the elbow, you should turnattention to the way you sleep. An incorrect position of the body can lead to a violation of blood flow, which will lead to unpleasant sensations. For example, get rid of the habit of sleeping with your hands thrown over your head: with this position your hands are above your body, and the cardiovascular system, slowing your work at night, can not "get" to them. If the right arm grows numb from the elbow to the wrist, note whether you are sleeping on the right side with a hand placed under the head. Everyone knows that sleeping on the left side is not very good, as the load on the heart increases, but on the right one you must sleep properly. Also, the cause of numbness of the upper limbs in a dream can be uncomfortable clothing, with stiff seams and folds. It should be free, not constricting movement, and decorating before going to bed is better to take off.
Other causes of numbness 
When the right arm grows numb from the elbow to the hand (orleft, or even both), you must carefully listen to your feelings. An inconvenient pillow or clothes are easily excluded, but the symptoms may remain. In this case, you should consult a doctor, since numbness of the upper limbs is a symptom of any disease, even life-threatening. For example, it can be a tunnel syndrome (it's a syndrome of the carpal tunnel). Numbness occurs due to compression of the median nerve with tendons and bones, which leads to severe pain and inflammation. This may be an osteochondrosis of the cervical spine, which acts like a high pillow, only getting rid of it is many times more difficult. The cause may be chronic disorders of the blood supply, which arise due to systemic disorders in the body - diabetes, coronary heart disease, anemia, hypertension, etc.
What to do?
This problem should not be dismissed.If numbness of the hands has become a constant companion of your life, you should consult your doctor. You will be given a checkup, which will establish the causes of numbness and plan the treatment. Take care of yourself and be well!
