Experiencing numbness or tingling in your hands can range from a minor inconvenience to a signal of a more serious underlying health issue. This sensation, often described as “pins and needles,” can stem from various causes. Let’s explore some potential reasons for this condition.

Improper Sleeping Position

One of the most common reasons for waking up with numb hands is pressure on the nerves due to sleeping in an awkward position. Lying on your arm or hand can compress nerves and restrict blood flow, causing temporary numbness and tingling. Changing your position often alleviates the sensation quickly.

Repetitive Motions

Using your hands for repetitive tasks, such as typing or using tools, can lead to nerve compression, contributing to tingling sensations. Carpal tunnel syndrome, caused by pressure on the median nerve in the wrist, is a common example of this.

Vitamin B12 Deficiency

Vitamin B12 is essential for nerve health. A deficiency can result in numbness or tingling in the hands and feet, along with other symptoms like muscle weakness and fatigue. This deficiency is more common in individuals with dietary restrictions, such as vegetarians or those with absorption issues like Crohn’s disease.
