Why does my hand keep falling asleep?

Answer

According to Medline Plus, the causes of numb and tingling hands include sitting or standing in the same position for a long time, a lack of blood supply to the area, an injury to a nerve or even a reaction to seafood toxins. The hands may also keep falling asleep because of certain medications, animal bites or bites from insects, ticks, mites or spiders.

MedlinePlus also cites other potential causes of the hands falling asleep including radiation therapy and nerve damage due to alcohol, lead, tobacco and chemotherapy drugs. Shingles and herpes zoster infection may also cause the hands to fall asleep. The hands may also fall asleep due to a lack of vitamin B12 or another vitamin, as well as abnormal levels of calcium, potassium or sodium. Pressure on the nerves of the spine and on the peripheral nerves also may lead to the hands falling asleep. MedlinePlus also explains that the tingling and numbness in the hands may also come from other medical conditions that include carpal tunnel syndrome. Diabetics also experience the sensation of their hands falling asleep. Migraines, multiple sclerosis, seizures, stroke, transient ischemic attack, underactive thyroid and Raynaud's phenomenon all may lead to the hands falling asleep.
