What causes numbness in the hand upon waking up that lasts all day, and what should I do about it?

Waking up with numb hands that persist throughout the day may be caused by physiological factors, or it could result from pathological conditions such as cervical spondylosis or carpal tunnel syndrome. Treatment options include general management and medication. Specific details are as follows:

I. Physiological Factors

During sleep, improper posture may compress the arm, obstructing blood flow and leading to hand numbness. This condition usually does not require special treatment. Appropriate physical exercise can help enhance immunity.

II. Pathological Factors

1. Cervical Spondylosis

When intervertebral discs in the cervical spine degenerate, disc protrusion or facet joint overgrowth may occur. During sleep, this can compress nearby cervical nerve roots, causing numbness in both hands. Medications such as diclofenac sodium sustained-release tablets or Jingfukang granules may be taken under a doctor's guidance.

2. Carpal Tunnel Syndrome

During sleep, blood vessels dilate, and if the median nerve is compressed within the carpal tunnel, the nerve compression becomes more pronounced, resulting in wrist numbness. Medications such as mecobalamin tablets or celecoxib capsules may be taken under medical supervision.

In addition to the above causes, hand numbness could also be due to cerebral hypoxia, cerebral hemorrhage, or cerebral infarction. It is important to get adequate rest and avoid excessive fatigue.
