Why Is My Leg Asleep?

The video explains the sensation of pins and needles, often experienced when a limb 'falls asleep.' This occurs when pressure is applied to blood vessels, reducing blood flow and causing numbness. Once pressure is relieved, blood flow resumes, and nerves send confused signals to the brain, resulting in a prickly sensation. The video advises avoiding prolonged pressure on limbs to prevent this sensation.
