Why do my hands go numb at night?
Nighttime hand numbness is most commonly caused by carpal tunnel syndrome, which compresses the median nerve when wrists bend during sleep. Other causes include sleeping position, cervical radiculopathy (neck nerve compression), or peripheral neuropathy. A wrist brace at night often helps.

Detailed Explanation
Waking up with numb hands is very common and usually treatable:
- Most Common Cause: Carpal Tunnel Syndrome

Related Questions
Why does my head hurt on one side only?
One-sided headaches are often migraines, cluster headaches, or tension headaches. Migraines typically cause throbbing pain with nausea and light sensitivity. Cluster headaches cause severe pain around one eye. Occasional one-sided headaches are usually not serious.
Why do I wake up with a headache every morning?
Morning headaches commonly result from sleep apnea, teeth grinding (bruxism), poor sleep position, dehydration, or caffeine withdrawal. High blood pressure and medication overuse can also cause them. Frequent morning headaches should be evaluated by a doctor.
Why does the room feel like it's spinning?
A spinning sensation (vertigo) is usually caused by inner ear problems like BPPV, vestibular neuritis, or Meniere's disease. It can also result from migraines or, rarely, stroke. Vertigo lasting more than a few days or with neurological symptoms needs medical attention.
