Arms or hands falling asleep at nightIf you’ve ever experienced the strange sensation of your arms or hands falling asleep at night, then you’ve probably also asked yourself why this occurs.

Continue reading to learn the causes of this sensation, as well as how to prevent and treat it and when you may need to see your doctor.

Why are my arms and hands falling asleep at night?

Your arms and hands tingling or falling asleep at night could be caused by a variety of reasons, ranging from harmless to severe. Some of these reasons include:

Sleeping position. If you are laying on your arm or hand for too long, your body weight will exert pressure onto the nerves and may cause issues with blood circulation. This can also constrict the arteries and disrupt blood flow, depriving the tissue of blood and nutrients and preventing your arm from sending signals to or properly interpreting signal sent from the brain.

Vitamin B. A lack of vitamin B can not only contribute to fatigue, paleness, and drowsiness, but may also cause numbness in the arms and legs, especially at night.

Work. If you are constantly performing tasks that utilize your wrists, such as sewing, typing, and using scissors as part of your daily work, your wrists and the nerves within them can become overloaded. This causes tingling and numbness in the arms and hands, as well as moderate pain.

Pinched ulnar nerve. Pressure on the ulnar nerve in your arm can occur if you are sleeping with your elbow bent, and result in the nerve becoming trapped or pinched. This can cause numbness and tingling throughout the arm.

Fluid retention. Being overweight and not exercising enough can cause swelling in the hands and feet known as fluid retention that can result in a tingling sensation felt especially at night.

Stroke. One in every seven strokes occur while the patient is sleeping, and symptoms include slurred speech, blurred vision, headache, tingling, and numbness.

Carpal tunnel syndrome. One of the first symptoms of carpal tunnel syndrome is numbness or tingling in the fingers at night that can radiate up the arm and into the shoulder.

Honeymoon palsy. This is when someone else puts pressure on a nerve on your outstretched arm, causing it to fall asleep. The radial nerve is commonly affected and it often results in a complete loss of sensation in your hands, arm, or experiencing a strong tingling sensation like pins and needles.

Saturday night palsy. This is when you fall asleep against a firm object, putting pressure on the nerves of the arm. The radial nerve becomes compressed resulting it falling asleep. The reference comes from having a long night out and falling asleep on a chair after drinking too much alcohol.

Diabetes. This metabolic disorder can result in many negative effects on the body, with nerve damage just being one of them. Over time, a condition called diabetic neuropathy may develop, leading to pain and numbness.

  • Alcoholism
  • Seizures
  • Low temperatures
