Why do my fingers go numb when I sleep

When people sleep, their whole body is basically in a state of stillness. In addition, unhealthy sleeping postures or maintaining the same sleeping posture for a long time may put pressure on the hands, which affects blood circulation, and over time may cause numbness in the fingers. In addition, if you are in an air-conditioned environment with your arms stretched out, and the indoor temperature is too low, it will also affect blood circulation, and then cause a feeling of numbness in your hands. In short, these phenomena are all related to numbness in the hands.

1 Under normal circumstances, numbness in the hands when sleeping is caused by poor blood circulation. For example, improper sleeping posture, pressing on the hands while sleeping, or maintaining the same sleeping posture for a long time will cause numbness in the hands. In addition, keeping your hands in a cold environment while sleeping can also lead to poor blood circulation in your arms and cause numbness in your hands.

Reason 2: Caused by cervical spondylosis

2 Cervical spondylosis is a common disease among middle-aged and elderly people. It is caused by the degeneration of human organs, which leads to herniation of cervical disc or hyperplasia or hypertrophy of articular processes, thereby compressing the local blood vessels and nerve tissues of the cervical spine, causing numbness of the hands during sleep.

Reason 3: Carpal Tunnel Syndrome

3 Numbness in the hands when sleeping at night may also be caused by carpal tunnel syndrome, which usually occurs in people who are engaged in work such as carrying, lifting, pinching, etc., and they often experience numbness in the hands and other parts of the body. This is because wrist trauma, sprain or wrist strain causes the transverse carpal ligament to thicken, the muscles inside the canal to swell, blood stasis and tissue degeneration, or carpal bones to degenerate and proliferate, which reduces the circumference of the canal lumen and compresses the median nerve, leading to numbness of the hands while sleeping.

Reason 4: Diabetes factors

4 If your hands and feet are not compressed and you often feel numbness when you sleep at night, it may be caused by diabetes. People with diabetes have relatively high blood sugar levels, which can easily damage blood vessels and nerves, leading to cold, numb and tight hands and feet. These are early symptoms of diabetic neuropathy and require prompt medical examination.
