A

It states Sleep is essential for revitalise and restore the body and mind it allow proper functioning

20
Q

What is the evolutionary theory

A

It states the humans and animals have developed sleep patterns to increase their chances of survival. All species have adapted to sleeping during periods of time when being awake would be most dangerous

21
Q

What is the information consolidation theory

A

This theory states people sleep in order to process information that has been acquired during the day
