Experiencing numbness or a pins and needles sensation in your arm during sleep is a common issue, often caused by sleeping on your side or stomach, which can compress nerves in the arm and shoulder. This is usually harmless and can be prevented by changing your sleeping position, wearing a wrist brace, or using a supportive pillow and mattress. However, if the issue is persistent or accompanied by other symptoms, it could indicate an underlying medical condition, such as vitamin B deficiency or carpal tunnel syndrome, and you should consult a doctor.

What You'll Learn

Side sleeping is best to prevent arm numbness
Sleeping on your side is considered the best position to prevent your arm from falling asleep during the night. This is because side sleeping is the least likely position to produce hand or arm numbness.
Sleeping on your stomach, for example, has been associated with nerve compression, as it is easy to flex your elbows under you or put your hands under your head. This can cause your arm to fall asleep. Similarly, sleeping on your back with your arms stretched overhead can also cause nerve pinching and lead to arm numbness.
If you are a side sleeper, you can avoid arm numbness by ensuring your wrists remain unflexed, as flexing can lead to tingling. You can also try sleeping with your arms by your sides or on pillows to keep your elbows and wrists in an ideal position.
If you are experiencing persistent or severe arm numbness, it is recommended that you consult a doctor to rule out any underlying causes.

Avoid sleeping on your stomach
Sleeping on your stomach can cause back, neck, and shoulder pain. It can also lead to headaches and arm pain. This is because the weight of your torso sinks into the mattress, causing your back to arch and your spine to move out of alignment. In turn, this can cause stress and strain, which may lead to aches and pains. To avoid this, you can try sleeping on your back or side.
If you sleep on your back, try to keep your arms by your sides, rather than overhead, to reduce nerve pinching. You can also try wearing a wrist brace to bed to stabilize your wrist and improve numbness in your hands and arms.
If you sleep on your side, try to keep your wrists straight. You can also put a pillow between your knees and ankles to align your hips. A full-body pillow can help you transition to side sleeping by providing warmth, pressure, and support.
It can take time to adjust to a new sleeping position, so be persistent and patient.

Try a wrist brace or splint
If you are experiencing persistent or severe arm numbness, it is recommended that you consult a doctor to rule out any underlying causes. In the meantime, a wrist brace or splint can be a good solution to prevent your arm from falling asleep at night.
Wrist braces or splints are designed to stabilise your wrist during sleep, ensuring that your wrist remains unflexed and reducing the likelihood of nerve compression. This is particularly important if you are at risk of carpal tunnel syndrome, a condition that can cause tingling or numbness in the limbs at night. By wearing a wrist brace or splint, you can help to keep your wrist in a straight and neutral position, reducing pressure on the nerves and improving blood flow to the area.
When choosing a wrist brace or splint, it is important to select one that is comfortable and not too tight, as this can defeat the purpose and cause additional compression. It should be soft yet supportive, providing a good balance between comfort and stabilisation. There are many different types of wrist braces and splints available on the market, so you may need to try a few different options to find the one that works best for you.
In addition to wearing a wrist brace or splint, it is also important to be mindful of your sleeping position. Avoid sleeping on your stomach, as this has been associated with nerve compression. Side sleeping is generally considered the least likely position to produce hand numbness, as long as your wrists are straight. However, even when sleeping on your side, it is important to ensure that your arms are positioned properly and that your wrists remain unflexed to prevent nerve compression.
By combining the use of a wrist brace or splint with thoughtful sleeping positions, you can significantly reduce the likelihood of your arm falling asleep at night, improving your sleep quality and overall comfort.

Avoid sleeping on your back with arms overhead
Sleeping on your back with your arms overhead can cause your arms to fall asleep due to nerve compression. This is when nerves in your arm and shoulder are compressed, causing a tingling sensation or numbness. If you often sleep in this position, try keeping your arms next to you instead, to reduce nerve pinching.
Nerve compression can occur when you sleep on top of your arm or pin it underneath a partner. This can cause compression neuropathy, which brings on a tingling sensation or numbness. Compression neuropathy occurs when the nerves in your arm and shoulder are compressed. The effect of compressing these nerves is like stepping on a garden hose: the information that flows from your extremities back to your brain is temporarily disrupted.
If you wake up with a numb arm, you can relieve the pressure by readjusting your sleeping position. Your arm will generally "wake up" and the tingling will stop. However, more chronic paresthesia may be a sign of an underlying medical issue, so you should consult a doctor if you experience persistent or severe arm numbness, or if it occurs alongside other symptoms.
There are a few other things you can do to avoid arm numbness at night. Firstly, you can try wearing a wrist brace to bed to help stabilise your wrist. You can also try sleeping on your side, which is considered the least likely position to produce hand numbness. Additionally, using a pillow and a mattress that provide efficient support can also help to prevent arm numbness.

Consult a doctor if it happens frequently
If you frequently experience numbness in your arms during sleep, it is important to consult a doctor to rule out any underlying health issues. While occasional episodes of "dead arm" are usually harmless and resolve quickly on their own, persistent or chronic numbness can indicate a more serious condition.
One possible underlying cause is nerve compression, which can occur when you sleep in a position that puts pressure on the nerves in your arm. This can lead to a condition called paresthesia, which is characterized by a tingling or "pins and needles" sensation. Paresthesia can also be caused by vitamin B deficiencies, so it is important to discuss any dietary changes or supplements with a healthcare professional.
In some cases, arm numbness during sleep can be a symptom of nerve damage or other underlying medical conditions. For example, it can be a sign of carpal tunnel syndrome, in which case wearing a brace or doing specific exercises may help. Additionally, numbness on one side of the body, including the arms, can be an indicator of a heart attack, especially if accompanied by chest pain or discomfort. If you experience these symptoms, seek immediate medical attention.
If you are experiencing persistent or severe arm numbness during sleep, it is important to consult a doctor to identify the underlying cause and determine the best treatment plan. They may recommend changes to your sleeping position, such as avoiding sleeping on your stomach or with your arms overhead, or suggest the use of a wrist brace or a supportive pillow and mattress to reduce pressure on the nerves.

Frequently asked questions
Arm numbness at night is usually caused by sleeping on your side and putting your arms in a position that puts pressure on a nerve in the limb. This can cause a feeling of "pins and needles" or numbness, also known as paresthesia.
Arm numbness as a result of sleeping posture is typically harmless and will subside on its own. However, if you experience persistent or severe arm numbness, or if it occurs alongside other symptoms, consult a doctor to rule out any underlying medical conditions.
To prevent arm numbness, try adjusting your sleeping position to one that does not put pressure on your hands or arms. Side sleeping with your arms curled in towards you, known as the fetal position, can help to relieve pressure on your arms and shoulders. You can also try wearing a wrist brace or using a supportive pillow and mattress to improve numbness in the arms.
In addition to sleeping posture, arm numbness can be caused by vitamin B deficiency, nerve damage, carpal tunnel syndrome, or other underlying medical conditions. If you suspect that your arm numbness is related to any of these factors, consult a healthcare professional for advice on treatment and management.
