Hand and arm numbness during the night that quickly returns to normal may be caused by multiple factors, including but not limited to the following:
1. Improper posture: Maintaining the same posture for a long time, such as having the arm compressed or placed under the head while sleeping, may temporarily compress nerves, leading to localized numbness.
2. Circulation problems: Poor blood circulation can also cause such issues. Especially in cold environments, blood vessels may constrict, potentially impairing peripheral blood flow and causing numbness.
3. Nerve-related diseases: Conditions such as diabetes and cervical spondylosis may affect nerve function, causing intermittent numbness.
4. Deficiency of certain nutrients: A lack of nutrients such as vitamin B12, calcium, and magnesium may also lead to abnormal nerve function and cause numbness.
To help prevent these issues, avoid maintaining the same posture for prolonged periods, perform appropriate neck and upper limb exercises to promote blood circulation. Additionally, maintaining healthy lifestyle habits such as quitting smoking, limiting alcohol consumption, and controlling body weight can help prevent related diseases.
