Numbness or tingling in the hands, often described as the “pins and needles” sensation, can be a puzzling and sometimes worrying experience. It can range from a temporary discomfort to a sign of an underlying health issue. Let’s explore some common and serious causes for this sensation.
1. Temporary Nerve Pressure from Sleep Position
One of the most common causes of hand numbness is sleeping in an awkward position that puts pressure on nerves. When you rest with your arm or hand under your head or body, it can compress the nerves, restricting blood flow. This results in the tingling or numb sensation you often feel when waking up. The good news is that shifting your position usually resolves this issue within moments.
2. Repetitive Strain and Carpal Tunnel Syndrome
Extended periods of repetitive movement, such as typing, using a mouse, or working with hand tools, can lead to pressure on the median nerve at the wrist, causing carpal tunnel syndrome. This condition results in numbness, tingling, or a “pins and needles” feeling in the fingers and hand. Rest and ergonomic adjustments can help, but severe cases may require medical treatment or surgery.
