What Causes Hand to Go Numb While Sleeping?

Have you ever woken up in the middle of the night with a numb hand? If so, you are not alone. Many people experience this sensation, known as numbness or tingling, in their hands while sleeping. While it may be a temporary inconvenience, it is essential to understand the underlying causes to address any potential health concerns.

The most common cause of hand numbness while sleeping is pressure on the nerves. There are several nerves running through the hand, such as the median nerve, ulnar nerve, and radial nerve. When you sleep in a position that puts pressure on these nerves, such as sleeping on your arm, the blood flow and nerve signals can get restricted, leading to numbness.

Another potential cause is carpal tunnel syndrome. This condition occurs when the median nerve, which runs from the forearm to the hand through a narrow passage called the carpal tunnel, gets compressed or squeezed. People who frequently engage in repetitive hand or wrist movements, such as typing or playing musical instruments, are more prone to developing carpal tunnel syndrome.

Besides pressure or compression, poor circulation can also lead to hand numbness while sleeping. When blood flow to the hand is restricted, it can cause tingling or numbness. Poor circulation can be a result of various factors, including underlying health conditions like diabetes or peripheral artery disease.
