My hands go numb at night
You wake in the dark and your hand feels dead. The fingers may tingle, buzz, prickle, or burn. Most people shake the hand or hang it off the bed until it wakes up.
This often means a nerve in the wrist is being squeezed. The median nerve runs through a narrow tunnel in your wrist. When the wrist bends, that tunnel gets tighter and the nerve gets pinched.
A key clue is which fingers go numb. Carpal tunnel hits the thumb, index finger, middle finger, and half the ring finger. The little finger is usually fine.
When to see someone
Call emergency services now if numbness comes on all at once in one arm, one leg, or one side of the face. Slurred speech, a drooping face, or sudden weakness may mean a stroke. Do not drive yourself.
See a doctor within a week if the numbness no longer goes away when you move the hand. Same if your grip is weak, or you keep dropping cups, keys, or a phone. Nerve pressure that lasts can leave lasting damage.
Book a visit soon if the muscle pad at the base of your thumb looks flat or sunken. That is muscle loss and it means the nerve has been squeezed a long time. Ask about a nerve test.
See a doctor if your feet are numb too, or if both hands and both feet burn. That points away from the wrist and toward diabetes, low B12, or thyroid trouble. A simple blood test can sort it out.
Go to urgent care for a wrist that is red, hot, swollen, or painful with a fever. Get seen right away if the numbness started after a fall, a crash, or a blow to the neck.
Why it happens
Most of us do not sleep with flat wrists. We curl them in, or tuck a hand under a cheek or a pillow. Held that way for hours, the nerve loses blood flow and starts to complain.
Fluid also shifts while you lie flat. During the day, fluid drains down toward your feet. At night it spreads out, and some of it settles in your wrists and hands.
Daytime work sets the stage. Typing, gripping tools, scanning items, or using a vibrating tool can swell the tendons in that tunnel. You feel it at night because there is nothing else to distract you.
What else it could be
Not all night numbness comes from the wrist. Which fingers go numb, and what makes it worse, tell you a lot.
Neck nerve pinch: the numbness runs in a stripe from the neck down the arm. There is often neck or shoulder pain too. Turning or tipping your head can set it off.
Elbow nerve pinch, called cubital tunnel: this hits the little finger and half the ring finger. It flares when you sleep with the elbow bent tight. Leaning on your elbow makes it worse.
Plain pressure: you slept on your arm and cut off blood flow. This one clears in a few minutes and does not come back once you move.
Nerve damage from diabetes or low B12: both hands and both feet are affected. It usually starts in the feet, not the hands. It feels like burning or like wearing socks and gloves.
Thyroid changes, pregnancy, and some medicines: these hold extra fluid, which crowds the wrist tunnel. Numbness in pregnancy often fades after the birth.
Raynaud's: fingers turn white or blue in the cold, then red and sore as they warm. Color change is the tell.
Stroke: one side of the body goes numb or weak all at once. The face may droop and speech may slur. This is an emergency, not a sleep problem.
How to read the grades below
The options below come from our page on Carpal Tunnel Syndrome. Each one carries two labels.
The first label is the evidence grade. A means strong trials in people, B means smaller or mixed studies, and C means early or limited findings. D means lab work only, and “insufficient” means the research cannot settle it yet.
The second label is the traditional tier. T3 means long use in more than one tradition, T2 means long use in one, and T1 means known use. T0 means no such record.
These grades come from research on Carpal Tunnel Syndrome, the parent Health Topic, not on my hands go numb at night.
A grade tells you how strong the research is, not how well something will work for you. Talk to a doctor or pharmacist before you start anything, above all if you take other medicines.
What to try first
Start with the wrist itself. A wrist splint keeps the joint straight while you sleep. It is the first step most doctors suggest for carpal tunnel, and it costs little to try.
Do not sleep on your hand or with the elbow folded tight. Try a pillow under the arm to keep it flat and level. Shaking the hand out helps in the moment but does not fix the cause.
Alpha Lipoic Acid (evidence grade A, traditional tier T0) has the most trial support of the options here. It has been studied for nerve pain and numbness, including before and after carpal tunnel surgery.
Bromelain (evidence grade B, traditional tier T0) comes from pineapple. It is used to calm swelling in the tissue around the nerve. PEA (Palmitoylethanolamide) (evidence grade B, traditional tier T0) is also graded B and is used for nerve pain.
Vitamin B6 (evidence grade insufficient, traditional tier T0) is a common home fix, but the trial results are mixed. Too much B6 can damage nerves and make numbness worse. Never take a high dose without your doctor watching it.
Acupuncture (evidence grade insufficient, traditional tier T3) has a long history of traditional use. That means long custom, not strong trial proof. Lymphatic Drainage Massage (evidence grade insufficient, traditional tier T0) is a gentle hands-on method aimed at fluid, and it also lacks solid trial backing.
Pick one thing at a time. That way you know what helped. Check with your doctor or pharmacist first if you take other drugs or you are pregnant.
How long it takes
A night splint often helps within one to two weeks. Some people notice a better night's sleep right away. Others need a month of steady nightly use.
Supplements work more slowly. Most studies run four to twelve weeks before they judge the result. If nothing has shifted by eight weeks, stop and rethink the cause.
If numbness is spreading or lasting into the day, do not keep waiting. That points to a nerve under steady pressure. Get it checked instead of trying another product.
