Why do body parts fall asleep, and what does it really mean? 🤔 A body part "falls asleep" due to temporary nerve compression, causing a "pins and needles" sensation known as paresthesia. This is usually harmless and resolves quickly by changing position to restore normal function. However, frequent or persistent numbness could be a sign of an underlying medical issue like nerve damage, diabetes, or a circulation problem! #science #physics #themoreyouknow #knowledge | Learning with Lyrics
