Summary

Waking up with numb hands is typically a sign of an issue with the circulation or the nerves in the arms. This can be due to falling asleep on the arms or with the hands in an awkward position.

Less commonly, waking up with numb hands could be a sign of an underlying health condition, such as carpal tunnel syndrome or a form of nerve damage.

Diagnosis generally involves tests to check the nerve function. If the doctor suspects a particular underlying cause, they may also order other tests specific to it. The type of treatment will depend on the diagnosis.

Numbness in the hands generally means that one of the nerves controlling the hands is compressed or lacking signal.

The three major nerves that lead to the hand are the ulnar, median, and radial nerves. Compression of these nerves can cause pain and numbness in one or more areas of the hand.

Issues that cut off blood circulation to the area may also cause numbness in the hands, along with other symptoms, such as nerve pain.

Nerve pain is a common issue in the United states, affecting around 7% to 10% of the population. There are several short-term and chronic conditions that can cause symptoms such as numbness in the hands, including:

Sleeping posture

Poor sleeping posture is a simple and common cause of waking up with numb hands. People may have slept on top of their hands or with their hands in a strange position.

Sleeping in an unusual position can put temporary pressure on the nerves or slow down circulation to a particular area, such as the hands. This pressure and lack of blood flow can cause symptoms such as numbness or a tingling sensation.

Avoiding sleeping on the hands or with the arms above or under the head may help prevent hand numbness upon waking.

Carpal tunnel syndrome

Carpal tunnel syndrome (CTS) may also cause numbness or tingling in the hands and wrists. CTS occurs when the median nerve in the hand becomes compressed, generally due to inflammation from overuse.

CTS can lead to symptoms such as pain, tingling sensations, and decreased hand strength. People who do more repetitive movements, such as using a cash register or typing on a keyboard for long periods, may be more likely to develop or experience CTS.

Diabetes

Diabetes is a chronic disease that occurs when the body cannot make or use insulin properly. It causes high blood sugar levels, which may lead to other complications.

Nerve issues are common among people with diabetes. The American Diabetes Association notes that about half of people with diabetes have nerve damage.

These nerve issues are more common in people who have had the disease for years. Controlling blood sugar levels carefully may help prevent or delay nerve damage.

Peripheral neuropathy

The peripheral nervous system sends nerve signals between the central nervous system and the rest of the body. There are different types of peripheral neuropathy, many of which cause similar symptoms, such as numbness, tingling, or painful sensations in the nerves.

Doctors may use imaging tests to check whether anything inside the body is putting pressure on the nerves. Nerve tests, such as electromyography and nerve conduction studies, may help doctors identify faulty nerve signals in the muscles, which could allow them to confirm a diagnosis.

Pinched nerve

Sometimes, numb hands could be a sign of a pinched nerve.

If inflammation or trauma causes the tissues in the body to put pressure on a nerve, the nerve may send faulty signals. These faulty signals could cause various symptoms, such as pain, weakness, and numbness, in the muscles of the affected area.

Cervical spondylosis

Cervical spondylosis, or arthritis in the neck, occurs as the disks in the spine wear down. This degeneration may occur due to trauma in the area, but it typically happens with age and general wear and tear.

Spondylosis can cause the space between the vertebrae in the neck to become thinner, which could pressure the nerves. If this occurs, it may cause symptoms such as numbness and tingling in the hands and arms. These symptoms can also affect other areas of the body, including the legs and feet.

Imaging tests of the neck can help doctors identify signs of osteoarthritis or cervical spondylosis.

Alcohol use disorder

Drinking too much alcohol over longer periods may also cause some symptoms of nerve damage, as excessive amounts of alcohol can damage nerve tissue. People who use alcohol very heavily may also have other issues, such as nutrient deficiencies due to a poor diet.

With a combination of these factors, it is not uncommon for people with severe alcohol use disorder to experience numbness, pain, or tingling in their limbs.

Neurological conditions

Some neurological conditions, such as multiple sclerosis (MS), can lead to numbness in the arms and hands. A person with a neurological condition may notice other symptoms, such as difficulty walking, changes in vision, or numbness or pain in other areas, such as the legs and feet.

Blood tests can help eliminate other possible conditions and check for markers of MS. Imaging tests, such as an MRI scan, can reveal any damaged areas in the brain that are causing symptoms.

Other conditions

Various other issues may lead to numbness in the hands, including:

Sjögren disease
syphilis
lupus
rheumatoid arthritis
Raynaud phenomenon
hyperthyroidism
Guillain-Barré syndrome
encephalitis
tumors in the brain or neck

Similar symptoms may also appear as a side effect of some medications, such as chemotherapy drugs or cardiovascular drugs.

Diagnosis and treatment of numb hands

If a person wakes up with numb hands, they should spend a few minutes trying to wake the hand up before seeking medical treatment. In doing so, they can be certain that the issue is not simply due to pressure after having slept in a strange position or on the hand.

To wake up the hand, a person should try shaking, flexing, and massaging it.

If the numbness goes away, this is likely an indicator that the numbness was simply due to pressure rather than to an underlying condition.

Anyone who suspects that an underlying condition is causing their symptoms should see a doctor for a diagnosis. Most diagnoses will involve imaging tests, such as X-rays, CT scans, or MRI scans, to look for signs within the body or brain.

Nerve tests will also help doctors evaluate nerve function and confirm a diagnosis.

In some cases, doctors will refer a person to a neurologist — a specialist brain doctor — who can make a more specific diagnosis and recommend treatment.

Exercise

For some issues, such as CTS or arthritis, exercise may help strengthen the muscles around the wrists, potentially improving symptoms.

Hand and wrist exercises may help stretch and strengthen the muscles in the area to relieve pressure on the joints. People with cervical spondylosis may also benefit from some posture exercises.

Topical creams

Some topical medications may help reduce symptoms such as pain or tingling in affected areas. The following drugs and ingredients may be effective:

lidocaine
benzocaine
menthol
capsaicin

Doctors may recommend topical creams to help manage symptoms of nerve pain in people with peripheral neuropathy or diabetic neuropathy.

Wrist guards

Splints or wrist guards help protect the wrist and relieve pressure.

People with CTS may find relief by wearing wrist guards when performing repetitive tasks or during times when symptoms usually show up. Some people may also benefit from wearing them while they sleep.

Medications

Treatments will vary depending on the severity of the symptoms and the person’s health status. Some possible treatments include:

tricyclic antidepressants
calcium channel blockers
serotonin-norepinephrine reuptake inhibitors (SNRIs)
opioid drugs
anti-inflammatories

A person should discuss taking medications with a doctor and take them according to a doctor’s advice.

When to see a doctor about numb hands

Anyone who is waking up with numb hands and experiences the following symptoms should see a doctor immediately:

weakness in the muscles or sudden loss of grip strength
numbness that travels into the arms, shoulders, or back
pain or numbness that lasts longer than the first few minutes after waking up

Sometimes, numbness may be a sign of a medical emergency, such as a stroke or heart attack. In this situation, the person will require emergency care, and they may have other symptoms.

In the case of a stroke, these may include:

confusion or trouble concentrating
difficulty speaking or forming words
sudden migraines
weakness or paralysis on one side of the body
loss of balance or dizziness
vision problems

If a person experiences numbness in the left arm and jaw due to a heart attack, they might also experience:

chest pain or discomfort
shortness of breath
lightheadedness
cold sweat

Anyone experiencing numbness in their hands alongside any of these other concerning symptoms should seek emergency medical care.

Summary

Numbness in the hands indicates that something is compressing the nerves in the hand or wrist.

This compression may occur due to simple issues, such as sleeping on the hand. However, it can be a sign of an underlying illness, either short-term or chronic.

Doctors may order several tests to check the nerves and confirm a diagnosis.

Treatment will vary depending on the underlying issue or condition. Some conditions may require long-term treatment to manage the symptoms.
