Have you ever woken up and realized one or both of your hands is completely numb and tingly? That “my hand fell asleep” feeling can be annoying at best and concerning at worst.
While brief hand numbness when waking is usually harmless, ongoing or worsening tingling and numbness can signal an underlying medical issue. Let’s explore what’s behind that pins and needles sensation when your hand falls asleep.
What Causes Hands to Fall Asleep at Night?
Many factors can cause your hands to temporarily lose sensation and “fall asleep” while you catch your zzz’s. Common culprits include:
- Sleeping in Odd Positions - Pressing your wrist at an awkward angle under your head or body can pinch nerves and restrict blood flow. Shifting position should wake your hand up.
- Medical Conditions - Carpal tunnel syndrome, arthritis, and diabetes can contribute to persistent hand numbness. See your doctor if symptoms don’t improve.
- Unhealthy Habits - Smoking, heavy drinking, and vitamin deficiencies may increase your risk of hand numbness.
- Chronic Stress - High stress levels can cause temporary numbness and tingling in the hands and feet. Try relaxing activities before bed.
While a bit strange, waking up with a numb hand is usually not cause for concern. But if it happens frequently or gets progressively worse, talk to your doctor.
The Creepy-Crawly Sensation of a Sleeping Hand
That numb, tingly feeling when your hand falls asleep stems from temporarily compressed nerves and reduced blood flow. You may experience:
- Pins and needles - A prickling, creeping sensation, like bugs crawling on your skin.
- Weakness - Trouble gripping objects firmly with an asleep hand.
- Pain - A dull ache or throbbing feeling when circulation returns.
- Loss of sensation - Not being able to feel touch, pressure, heat or cold.
The medical term for this sensation is paresthesia. It usually goes away within minutes as circulation returns. Try shaking out your hand to speed things up!
Tricks for Waking up a Sleeping Hand
Got a case of numb hand syndrome at night? Try these tips to get back that hand strength fast:
- Massage your hands - Rubbing and kneading boosts blood flow to numb areas.
- Shake it out - Flapping your hands can help wake them up in seconds.
- Stretch and flex - Extend your fingers, wrist, and arm fully, then make a fist.
- Get upright - Let gravity help by dangling your arms by your side or over your head.
- Use a wrist brace - Splints keep your wrist in a neutral position while sleeping.
- Watch your sleep position - Avoid sleeping with wrists curled under or arms overhead.
- Exercise your hands - Regular strength training improves circulation.
Recurring numbness or tingling is not normal. See a doctor if it happens frequently or gets worse over time. Persistent hand numbness can point to carpal tunnel syndrome, nerve damage, or other medical issues that need treatment.
Sleep Tight Without Numb Hands
While occasional nighttime hand numbness is usually harmless, take steps to sleep more comfortably and prevent recurrences:
- Use a hand pillow - Keep wrists straight with a soft brace or pillow under your palms.
- Watch your posture - Sleep on your back or side, not on your stomach.
- De-stress - Try calming activities like yoga before bedtime.
- Limit alcohol - Heavy drinking can contribute to nerve issues and numbness.
- Stop smoking - Smoking constricts blood vessels, decreasing circulation.
- Exercise - Regular activity improves nerve function and blood flow.
- Try a vitamin B supplement - B vitamins support healthy nerves.
Don’t ignore persistent hand numbness, pain, or loss of coordination. Bring up any worrisome symptoms with your doctor promptly. Catching and treating any underlying medical conditions early leads to better outcomes.
With simple lifestyle tweaks and awareness of your sleeping positions, you can rest easy without waking up to numb, tingly hands. Pay attention to any symptoms and talk to your doctor if they persist. Sweet dreams!
Frequently Asked Questions About Numb, Tingly Hands
Hand numbness when sleeping is frustrating but common. Here are answers to some frequently asked questions about how to prevent and treat nighttime hand tingles:
Why do my hands go numb while sleeping?
The most common cause of hands falling asleep at night is compressed nerves or restricted blood flow from sleeping in awkward positions. Sleeping on your hands or with your wrists bent can put pressure on nerves and arteries. Medical conditions like carpal tunnel syndrome can also contribute to nighttime hand numbness.
How can I stop my hands from falling asleep when I sleep?
Use a hand pillow or brace to keep your wrists straight. Avoid sleeping on your stomach or sides with your hands tucked under your head or body. Don't sleep with your hands overhead or twisted into unnatural angles. Proper sleep posture goes a long way towards preventing hand numbness.
What's the best sleeping position to avoid numb hands?
The best sleeping position to avoid numb hands is on your back with arms relaxed at your sides, palms up. Or try side sleeping with a supportive pillow under your top arm to keep your wrist straight. Avoid positions that compress your wrist or twist your arms into unnatural angles.
What does it mean if my hands are numb every morning?
Occasional morning hand numbness is usually harmless. But if you wake up with numb, painful, or weak hands daily, see your doctor. Persistent numbness, especially if worsening over time, can indicate an underlying condition like carpal tunnel syndrome, arthritis, or nerve damage.
Can carpal tunnel cause hand numbness while sleeping?
Yes, carpal tunnel syndrome is a common cause of hand numbness and tingling at night. Carpal tunnel causes pressure on the median nerve as it passes through the wrist. Nighttime hand numbness or painful tingling are classic symptoms of carpal tunnel.
Why do my hands fall asleep when I drink alcohol?
Drinking alcohol can contribute to hand numbness in a few ways. Alcohol dehydrates the body, which can compress nerves. Alcohol also expands blood vessels, allowing hands and feet to get colder. This vein expansion combined with alcohol's sedative effects can make hands more prone to falling asleep.
How can I wake up my hands quickly when they fall asleep?
Shaking out and massaging your hands vigorously will wake them up fast by improving blood flow. Letting your arms dangle by your sides uses gravity to get circulation going again. Stretching and flexing your hands and wrists also helps return sensation.
When should I worry about hand numbness?
Occasional brief hand numbness is normal. But see your doctor if you have persistent numbness, tingling, pain, or loss of coordination in your hands. Worsening symptoms or numbness combined with weakness can indicate an underlying condition needing medical treatment.
Are there any exercises or stretches to help with hand numbness?
Hand and wrist mobility exercises can aid circulation and nerve function. Try gentle stretches, finger and wrist rolls, and range of motion movements. Strengthening exercises like hand grips and squeezes can also counter weakness from nerve compression. Check with your doctor before starting any new hand exercise program.
