Why does your body become numb and have tingling sensation while sitting for a few minutes /hours in one position but doesn’t become numb for 7+ hours of sleep in the same position?

its really more about blood flow than how static you are. When you’re lying down and sleeping you’re generally in a very neutral position and blood flow is uninterrupted however if you’re sitting in a way that interrupts bloodflow like sitting on your knees or with your legs crossed, your nerves, which depend on oxygen rich blood to send signals, will begin to have issues transmitting signals and you will get the tingling sensation. as soon as you stand up or shift position and bloodflow resumes it will go away.
