What causes numbness in the arm during sleep?

Generally, numbness in the arms and hands during sleep may be caused by cold exposure, improper posture, cervical spondylosis, carpal tunnel syndrome, cerebral infarction, etc. It is recommended to seek medical attention promptly to determine the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Cold Exposure

If adequate warmth is not maintained during sleep, leading to cold arms, it may result in poor blood circulation, causing the aforementioned symptoms, possibly accompanied by chills and shivering. It is advised to improve保暖 measures by appropriately covering the arms and hands with blankets or quilts.

2. Improper Posture

Remaining on one side for prolonged periods during sleep may obstruct local blood circulation, resulting in arm numbness, sometimes accompanied by soreness or weakness. It is recommended to adjust sleeping positions and avoid prolonged pressure on the arms.

3. Cervical Spondylosis

This condition is usually caused by physical strain. During sleep, compression of nerves or blood vessels in the cervical spine may lead to arm numbness, often accompanied by neck pain and stiffness. Treatment may include medications such as mecobalamin tablets, Shujin Huoxue tablets, or celecoxib capsules, taken under medical guidance.

4. Carpal Tunnel Syndrome

Typically caused by fractures or dislocations, this condition may compress the median nerve, leading to arm numbness, pain, and weakness during sleep. Treatment options under a doctor’s supervision may include meloxicam capsules, triamcinolone acetonide injection, or methylprednisolone injection.

5. Cerebral Infarction

Caused by blockage of blood vessels in the brain, this condition may lead to neurological dysfunction, manifesting as arm numbness, aphasia, hemiplegia, etc. Symptoms may worsen during sleep due to immobility. Under medical guidance, medications such as clopidogrel hydrogen sulfate tablets, atorvastatin calcium tablets, or rosuvastatin calcium tablets may be used for treatment.

In daily life, it is important to develop healthy habits, such as going to bed early and waking up early, aiming to fall asleep before 11 p.m. each night, avoiding late nights, and ensuring sufficient sleep. Diet should be light and easily digestible. Consuming nutrient-rich foods such as lean meat, fish, eggs, milk, and carrots can help enhance immunity.
