Why don't people often fall out of bed when they are sleeping?

Question

What function stops us from just rolling off?

Answer 1

Sometimes people do fall out of bed. But there is a good reason. Much like a computer, our mind has different stages of running power. When we sleep normally, this could be compared to a stand by state-we are resting,b ut are ready to get up and back to work at a few moments notice. When we are deep asleep, this could be considered hibernation,a nd it'll take us alot to get out of it. Hnece when we fall out of bed-we took to long to notice how close tot he edge we were lol.

Answer 2

the body got a hang of the bed, like the body knows the width and length of the bed...

try this experiment use your bed (like always)and then use a narrow sided bed and once know it you'll notice that you fell down from the bed...

because they are not in the deep sleep and always aware of the surroudings.the people who fall are in deep sleep and that is good too.
