Why do our legs shake if we lift our heels whilst sitting down?
In: Biology
Can you clarify?
Just lifting my heels off the ground while sitting, mine do not shake….if you instead are referring to people that “bounce” their legs up and down, that’s completely different. Their legs aren’t shaking they’re bouncing them by pressing their toes into the floor which causes the heel to rise.
Now as to why people do it, there’s a few different reasons. Some do it out of boredom, some do it when extremely focused on something, some do it as a form of nervous tic.
Regardless, their legs don’t “shake” *because* their heel is off the ground, their heel is off the ground because they are “shaking” (more of a bounce IMO) them.
