Many people experience numbness or a pins and needles sensation in their hands when they wake up. This is usually caused by sleeping in a position that puts pressure on the wrist, elbow, or shoulder, which can restrict blood flow and compress nerves. However, persistent hand numbness or numbness accompanied by other symptoms such as slurred speech, weakness, or paralysis may be a sign of an underlying medical condition and should be evaluated by a healthcare professional.

| Frequency | Occasional numbness is usually not a concern |
| Duration | Temporary numbness is usually not a concern |
| Sleeping position | Sleeping in a position that puts pressure on the wrist, elbow, or shoulder can cause hand numbness |
| Other symptoms | Slurred speech, loss of bowel and/or bladder control, numbness in other parts of the body, weakness, paralysis, or a sudden severe headache |

What You'll Learn
Temporary issue: Pressure on a nerve during sleep
Waking up with numb hands can be caused by sleeping in a position that puts pressure on your wrist, elbow, or shoulder, which can restrict blood flow and compress nerves. This can usually be remedied by adjusting your sleep position and using pillows for support, especially under your arms or between your shoulders and the mattress.
If you wake up with numb hands, your body is sending you a message. It's important to figure out what's causing the numbness so that you can take action to relieve your discomfort and protect your nervous system. Certain sleeping positions can compress nerves in the hand, wrist, arm, or elbow, producing numbness and tingling.
If you notice numbness or tingling in your hands when you wake up, you can try the following:
- Change your position: Shift your body or sit up to relieve any pressure that may be compressing a nerve. Avoid sleeping with your arms overhead or tucked under your body.
- Gently move your hands and fingers: Slowly stretch, shake, or massage your hands to improve circulation and stimulate nerve activity.
- Use pillows: Use a pillow that supports your sleeping position. For back sleepers, a thinner pillow helps maintain spinal alignment.
If the numbness persists or occurs with other symptoms, it is important to seek medical attention.

Underlying medical condition: Nerve damage, circulation, immune system
Experiencing numbness or a "pins and needles" sensation in your hand is usually caused by nerve compression or damage, which can be temporary or chronic. Temporary paresthesia, or abnormal nerve function, can occur when you sleep on your arm or hand, or when you sit in a position that puts pressure on a nerve for too long. This can cause a temporary lack of blood flow to the area, resulting in numbness or a "pins and needles" feeling. Changing your position usually relieves these symptoms.
However, chronic circulatory issues caused by underlying medical conditions can also cause hand numbness. These conditions include nerve damage, which can be caused by several factors, including vitamin B12 deficiency, wrist injuries, and carpal tunnel syndrome. Vitamin B12 is essential for healthy nerve function, and a deficiency can lead to nerve damage and sensory disturbances, including numbness or tingling in the hands and feet. This deficiency is more common in older adults, people with gastrointestinal issues, and those following a vegan diet.
Wrist injuries can lead to carpal tunnel syndrome, a type of compression neuropathy that occurs when a nerve in the wrist becomes compressed in a tight channel. This can cause pain, numbness, and weakness in the hands. Additionally, injuries to the neck, such as whiplash, can also affect nerve function in the hands. Age-related wear and tear of the cervical spine, known as cervical spondylosis, can lead to nerve compression and subsequent numbness or tingling in the hands. Chronic alcohol use can also damage peripheral nerves, resulting in alcoholic neuropathy, which often affects the hands and feet and causes numbness, tingling, and weakness.
Furthermore, certain medications can damage peripheral nerves and lead to peripheral neuropathy, which is a term for several conditions involving damage to the peripheral nervous system. Chemotherapy, for example, can cause peripheral neuropathy in 30% to 68% of people undergoing treatment. Other medications that may contribute to peripheral neuropathy include anticonvulsants, heart and blood pressure medications, and antibiotics such as metronidazole and fluoroquinolones. Peripheral neuropathy can also be caused by infections, inflammatory conditions, and autoimmune diseases that affect the nerves.

Carpal tunnel syndrome
Waking up with a numb hand can be caused by certain health conditions, sleeping positions, medications, and nutrient deficiencies. If numbness persists, a doctor can help determine the cause and the best course of treatment. One of the most common causes of hand numbness is carpal tunnel syndrome.
The symptoms of carpal tunnel syndrome usually develop slowly and are often first noticed at night, with pain or tingling waking the person up. Over time, the symptoms may start affecting the person during the day, especially if they perform repetitive motions with their hands, such as typing, writing, or using tools. Carpal tunnel syndrome can make it difficult to hold or control objects and may cause a feeling of discomfort in the wrists, hands, and fingers.
Treatment options for carpal tunnel syndrome include wearing a splint, physical therapy, anti-inflammatory medication, and, in some cases, surgery. It is important to seek medical attention if you are experiencing symptoms of carpal tunnel syndrome to prevent permanent damage to the median nerve.

Vitamin B12 deficiency
Waking up with a "sleepy" hand is likely nothing to be concerned about if it happens occasionally and the feeling goes away after repositioning your hand. However, if the numbness persists or is accompanied by other symptoms, it could be a sign of an underlying medical condition, such as vitamin B12 deficiency.
Vitamin B12 is an essential nutrient that plays a crucial role in the body's nervous system. It is naturally present in animal-based foods such as meat, poultry, eggs, dairy, and fish. Vegetarians and vegans can obtain vitamin B12 from fortified cereals, plant-based milk, bread, and nutritional yeast. However, people following a strict vegetarian or vegan diet are at a higher risk of developing a vitamin B12 deficiency if they do not consume vitamin B12 from fortified foods or supplements. Weight-loss surgery can also interfere with the body's ability to absorb vitamin B12 from food.
If you suspect that your hand numbness may be related to vitamin B12 deficiency or any other nutrient deficiency, it is recommended to consult a healthcare provider. They may suggest dietary changes or supplements to address the deficiency and alleviate the symptoms. Early detection and treatment are crucial to prevent the development of severe neurological problems and blood diseases.

Peripheral neuropathy
Numbness in the hands can be caused by various factors, including sleeping positions, medications, nutrient deficiencies, and certain health conditions. One potential underlying condition is peripheral neuropathy, which is a result of nerve damage in the body's extremities, such as the arms, hands, and feet.
There are several factors that can contribute to the worsening of peripheral neuropathy symptoms at night. Firstly, body position during sleep can affect the intensity of numbness and nerve pain. For example, sleeping on the side may worsen numbness in the arm or leg. Additionally, physical strain, vigorous exercise, and a lack of daytime distractions can increase the perception of nerve pain at night.
Furthermore, temperature changes at night can influence nerve endings, resulting in a tingling or burning sensation. Lower body temperatures during sleep may be interpreted by damaged nerves as pain or tingling, intensifying the sense of neuropathy. This can be further exacerbated by poor sleeping habits, which can heighten the body's sensitivity to pain.
To manage peripheral neuropathy and improve sleep, it is crucial to address the underlying cause. This may involve treating vitamin deficiencies, adjusting medications, or seeking medical treatments such as spinal cord stimulation or acupuncture. Establishing a consistent sleep schedule, maintaining a cool and dark bedroom environment, and practising relaxation techniques can also promote better sleep.
In summary, peripheral neuropathy can be a potential cause of hand numbness and can significantly impact sleep quality. By understanding the factors that worsen neuropathy symptoms at night and implementing effective sleep strategies, individuals with peripheral neuropathy can improve their sleep and manage their symptoms more effectively.
