What Causes Hand Numbness in Middle-aged and Elderly People?

　　In general, hand numbness in middle-aged and elderly individuals may be caused by age-related factors, excessive pressure, nutritional deficiencies, cervical spondylosis, Raynaud's phenomenon, or other causes. Symptomatic management through general treatment, physical therapy, and medication may be necessary. If discomfort occurs, timely medical consultation is recommended, with treatment conducted under a physician's guidance. Detailed explanations are as follows:

　　1. Age-related factors

　　With aging, degenerative changes in the nervous system and vascular hardening may lead to poor hand circulation. These changes can cause abnormal sensations in the hands, possibly accompanied by weakness and reduced dexterity. It is recommended to perform regular hand exercises and massage to promote blood circulation.

　　2. Excessive pressure

　　If middle-aged and elderly individuals maintain the same posture for prolonged periods, especially positions that compress the hands, it may lead to impaired circulation and subsequent numbness. Adjusting sleeping and sitting postures, avoiding prolonged hand compression, and applying heat or cold compresses when necessary can help alleviate symptoms.

　　3. Nutritional deficiencies

　　Due to unbalanced diets or decreased digestive absorption capacity, middle-aged and elderly individuals may develop nutritional deficiencies, especially of B vitamins essential for nerve health, which may lead to hand numbness. This may be accompanied by dry skin, fatigue, and weakened immunity. It is recommended to adjust dietary patterns and increase intake of B vitamin-rich foods such as whole grains, legumes, and nuts.

　　4. Cervical spondylosis

　　Chronic strain and degeneration of the cervical spine may lead to cervical spondylosis. Compression of nerve roots caused by cervical spondylosis can interfere with nerve signal transmission to the hands, causing numbness. Cervical instability or disc herniation may compress nerve roots, leading to abnormal hand sensations. Following medical advice, physical therapies such as cervical traction and physiotherapy may help relieve symptoms.

　　5. Raynaud's phenomenon

　　Raynaud's phenomenon is a vascular disorder. When exposed to cold or emotional stress, small arteries in the fingers spasm, reducing blood flow and causing color changes and numbness in the fingers. During Raynaud's attacks, fingers first turn white, then blue, and finally red, accompanied by pain or a prickling sensation. It is recommended to use medications such as nifedipine tablets, diltiazem hydrochloride tablets, or captopril tablets under medical supervision.

　　Middle-aged and elderly individuals are advised to maintain proper sitting and sleeping postures, avoid prolonged periods of looking down at mobile phones, and prevent cervical spine compression and nerve signal disruption.
