The sleep process

Relaxing

Sleep is promoted when your mind comes to rest before you go to sleep. Going to bed immediately after a sporting activity is not recommended; neither is working until midnight and then immediately going to sleep.

Falling asleep

It is not easy to pin point the transition between being awake and being asleep. It seems to be more of a gradual process than a sudden transition. We slowly become less aware of our surroundings.

Sleeping

Sleep is a state of physical rest and reduced awareness. It is generally assumed that the main function of sleep is to allow the body and the brain to recover.
