Have you ever woken up with numbness or tingling sensations in your hands? If so, you’re not alone.

The good news is that this pins-and-needles sensation isn’t dangerous on its own. According to the Mayo Clinic, “Numbness alone isn’t usually associated with potentially dangerous disorders, such as strokes or tumors.”

Fortunately, numbness or tingling in your hands can often be addressed easily. One common cause is your sleeping position. If you sleep with your hands under your body, you might wake up with a loss of sensation in your hands.

Additionally, repetitive hand and finger movements, such as typing, writing, or using tools, can cause this sensation. These movements can compress the nerves over time, leading to conditions like carpal tunnel syndrome, which affects the median nerve in the wrist. According to Healthline, “If the condition persists, it can cause permanent nerve damage. Sometimes surgery is necessary to relieve the pressure.”
