What would make your head fall asleep and be numb when you go to bed at night?

A numb or tingling sensation in the head when going to bed could be caused by poor circulation, nerve compression, or tension in the neck and shoulders. This might occur if you sleep in an awkward position or use an unsupportive pillow. Additionally, anxiety or stress could contribute to muscle tension, leading to discomfort. If the sensation persists, it may be wise to consult a healthcare professional for a thorough evaluation.
