Have you ever woken up in the middle of the night feeling your hands or feet go numb? This sensation, often described as “falling asleep,” is known medically as paresthesia. While it is often a harmless result of temporary nerve compression, persistent tingling can be a signal from your body that something more serious needs attention.
🔍 Common Causes of Numbness
1. Nerve Compression (The Most Common)
Often caused by poor sleeping posture or sitting in one position for too long. When you “pinch” a nerve, the signals to the brain are interrupted. Once the pressure is released, the “pins and needles” sensation occurs as the nerve begins to fire correctly again.
2. Carpal Tunnel Syndrome
Frequent tingling in the fingers and palms is often linked to the compression of the median nerve in the wrist. This is common in individuals who perform repetitive tasks, such as typing or manual labor.
3. Peripheral Neuropathy (Diabetes)
Chronic high blood sugar can damage the delicate nerve fibers in the extremities. This is a leading cause of persistent numbness in the feet for those with diabetes.
