Why does my hand fall asleep at night?

If you are worried about having a stroke, take an aspirin a day just in case you do have one, as it will lessen the effects of a stroke and may save your life.\nHowever, my ex was experiencing numbness in the hands and the doctor found a spur on the back of his neck on the spine that was causing all the numbness. He gave him an anti-inflammatory drug that helped. It stops the swelling and irritation of the muscle and nerves around the spur. You would have to see a doctor before you will really know what is causing it. God be with you.

Often enough the dark circles come from touching or rubbing your eyes with your fingers too often. If you get enough sleep, but still have dark circles, try no to touch your eyes for a few days, you'll notice the difference.

How do you sleep? If you find you have your hands under your body, it could be a pinched nerve like other said. Also, you might reflexively clench your hands in your sleep (sorta like how some people grind their teeth and require a mouthguard to sleep). If that is the case, try to get carpal tunnel hand braces to resist this.\n\nRegardless, I would discuss the possibilities with your doctor when you see him/her next.

Sounds like a neck problem or a TOS (thoracic outlet syndrome).  In other words, the nerves and blood vessels to your hands come out of your neck, run through your arm pit and down your arms.  Either bad posture or some type of physiological problem is pinching the nerves and/or blood vessels causing a numbing/burning sensation.  It probably feels close to like if your hand falls asleep.  I would recommend getting an examination from a Chiropractor.  Find one that not only adjusts but works with physical therapy to address muscular problems as well.  You should see someone as soon as possible about this becuase it will likely get worse and could lead to or further existing arthritis or disc problems in your neck.  Of course, it could always be something more serious so check with a healthcare professional (I definately recommend Chiropractic, and yes, I am biased but I know I am right too...)

Really good chance that your sleeping style could have something to do with it.  Try and notice if it may occurr more when your upper arm is raised greater than or equal to 90 degrees (above the shoulder).  It is a symptom of shoulder impingement syndrome where the nerves that run through the sub-acromial space are compressed within this small cavity, causing the parasthesia that you are experiencing.  To find out more, type in shoulder impingement syndrome on any search engine.

MY HANDS ARE LIKE THAT TOO. WHEN I USE THE COMPUTER THEY REALLY GET COLD OR WHEN I READ A BOOK. AS LONG AS I KEEP MOVING THEM THEY'RE OK. JUST PART OF GROWING UP.

Could be poor circulation or just a random ache.  You may have pinched a nerve when you slept.  It should go away soon, so don't worry about it.

Might be because of too much sleep

The brain has a separate neural pathway to the optical nerve, separate from the visual path, to detect whether it's day or night.  so when its dark, the brain believes it is nightime and the sleep cycle may inadvertently kick into motion, especially if you're already tired.

First, numbness in the LOWER extremitiies is a sign of diabetes not a numb or tingling finger.  However, I used to wake up with my forearms and hands completely numb which made that first morning trip to the bathroom extremely difficult.  A doctor recommended that I quit sleeping with my arms crossed over me or in any other way bent.  It was difficult to train myself to sleep with my arms straight, but once I finally did it, the numbness subsided.  That was sue to ulnar entrapment/pressure.  Also, when I was younger and would drink on the weekends I would wake with painfully numb hands.

Kite Girl, you are probably anxious or depressed. Insomnia of Anxiety Neurosis is characterized by difficulty with falling asleep. However, once asleep they sleep through. With Depression, the individual is able to fall asleep but wakes up in the middle of the night (2-3am) and is unable to fall back to sleep. In any case, I think your problem is a mental one. Consider seeing a neurologist or a psychiatrist to properly evaluate this problem.\n\nBut before you go see a doctor, have you tried using a soporific? (e.g. a cup of cocoa/chocolate drink with plenty of milk at bedtime.)

I have no idea why your hand is doing that, but I can tell you why mine does that.\n\nI paint a lot, do yard work and have gymnastic type activities in my background and about 1 1/2 months ago, my hands (both but mostly my right) swelled, tingled and went numb mostly in my thumb and middle finger(s). So painful that it would actually wake me up at nights about a week after it started. I went to the doctor and had x-rays done on my wrists (I thought it was carpel tunnel syndrome) and it turned out that I have occult ganglion cysts, the kind in the middle of the wrist bones not the kind that come OUT of the wrist bones. The cyst puts pressure on the nerves in my hand. \n\nSo, the doctor told me to sleep with wrist splints on for at least 3 weeks to see if that would help (to keep the cysts from getting agitated so they could go down on their own). That has helped with the pain and swelling, but my middle fingers are still numb but no longer tingle. I'm still able to do every thing I always do, but use my splints during the day when I use yard tools.\n\nAnyway, that's my story. Good luck!

It sounds like your not drinking enough water. I could be wrong but, usually when you are falling asleep like that, it is lack of oxygen in your blood stream. Your VO2 max has mostly to do with oxygen getting to the muscles while you workout. No, your VO2 max has nothing to do with this. How much are you sleeping? If you ride alot, you need at least 7-8 hours of rest a night.

Thoracic Outlet Syndrome can cause swelling of the hands at night.  This is a condition of the neck, shoulder, and upper chest that causes compression of the neurovascular bundle (artery, vein, lymphatics and nerves) as they pass through the neck and shoulder and into the arm.  It is usually the result of a significant 'whiplash' (technically called a Cervical Acceleration/Deceleration injury).  \nThere can be other causes of hand swelling, but this is fairly common and usually overlooked by healthcare professionals.\nGood luck.

I know someone that this happened to and they had damaged a nerve in their head from sleeping on the couch, laying their head on the arm rest. They had to get an MRI or something to figure it out, but they're just giving it time to see if it heals itself otherwise there's some kind of surgery. Might be your problem.

repetitive motion sydnrome??  carpal tunnel?  Do you do the same thing for long hours every day?  Or play tennis?  Might be tennis elbow too.  I would see a doc about it if it has been happening for several days.  Or maybe you're sleeping on it funny?\n\nOr it might just be Tom Cruise.  He really gets on my nerves and makes them act up.  Maybe he's getting on yours too!

I'm assuming you mean sleep paralysis.\n\nThe precise cause is not actually known; it is believed to be a neurologic malfunction.  In normal sleep, your body is periodically put into non-movement mode; one of the theories (not necessarily proven) is that the paralysis occurs by the same mechanism at an inappropriate time.
