![]() ![]() To alleviate the potentially tight muscles in the chest and shoulder, a simple stretch has been shown. So how stop the numbness? First of all, avoid sleeping with your arms over your head or curled up in front of you. If you combine this scenario with your arm in the previously mentioned sleeping positions, you are even more vulnerable to experience the numbness. If these muscles are only mildly tight but not enough to cause numbness, the overall space that the nerves have to pass through is still less. This can also compress the nerves as they pass through the shoulder and give the same result of numbness. Also, if you spend too much time at the computer or drive for long distances, the muscles in the chest and shoulder can become very tight. The resulting numbness in the arm and hand will occur again for the same reason. This position causes compression of the nerves as they pass through the shoulder and into the arm area. Your arms are likely curled up tight in front of your chest. This can also happen to those of you that prefer to sleep curled up into the fetal position. ![]() This will eventually make your hand and arm feel numb and weak. So, if the nerves become stretched, they cannot communicate their message to the spine properly. Your brain then consciously tells you that your hand is being touched. For example, if a water droplet hits your hand, a message from the hand is sent through the nerves to the spinal cord and then to the brain. When this happens, the nerves cannot perform their job as well. When someone sleeps with their arm under their pillow or over their head, the bundle of nerves can become mildly stretched. The primary function for most of these nerves is to control pain or touch sensations and the contraction of the muscles of the arm. The bundle of nerves then pass under the chest muscles, through the shoulder and down the arm. These nerves exit the spine between each of the vertebrae and combine together into a large bundle of nerves. Originating from the spinal cord, there are eight nerves. Passing inside of vertebrae is the spinal cord. The neck portion of your spine, the cervical spine, has seven vertebrae. The technical term is referred to as “thoracic outlet syndrome”. This is commonly caused by compression of the nerves and blood vessels that enter the arm. ![]() Do you frequently wake up at night because your hands and lower arms have gone numb or “asleep”? You may find that it happens when you are sitting at a desk or even when driving long distances. ![]()
