The Science of Sleeping

What goes on in your brain when you're asleep?

Ever wondered what goes on in your brain when you’re asleep? If you thought REM is just the name of a band, think again. There’s a science to the way you sleep, and it’s anything but a snooze-fest.

When you sleep your body rests and restores itself. However, sleep is an active state that affects both your physical and mental well-being. Sleeping is a natural cycle of activity in the brain and consists of two basic states: rapid eye movement (REM) and non-REM sleep, which consists of four stages.

What is REM sleep?
The period of REM sleep is marked by extensive physiological changes. It is the only sleep stage in which you dream. REM sleep occurs 90 minutes after sleep onset. The first period of REM typically lasts 10 minutes with each recurring REM stage lengthening until the final one – which lasts one hour.

What is NREM sleep?
The period of NREM sleep is made up of stages one through four. Each stage can last from five to fifteen minutes. Stages two and three repeat backwards before REM sleep is attained.
