Why Do Our Fingers Curl While We Sleep?

The video explores why fingers curl during sleep, highlighting the role of muscle relaxation. It explains that while fingers lack muscles, tendons connected to muscles in the palm and forearm control their movement. During sleep, muscles relax, causing fingers to curl slightly due to the balance between flexor and extensor muscles. External factors like palm position also influence curling. Understanding this can help in convincingly feigning sleep.
