#1

The brain waves of a person in coma or under anesthesia are very slow and weak, while the brain waves of a person during sleep are often as perky as when they’re fully awake. This allows our sleeping brain to dream, organize, and store memories.

#2

The brain can be affected by exhaustion. Some brain cells go to sleep while the rest stay awake, and this is known as a microsleep. It usually occurs when we stay awake too long.

#3

Over the past fifty years, the amount of sleep adults get has decreased. The average adult now sleeps about seven hours a night. While we don’t know if this is good or bad for us, we do know that sleep is important for our health.

#4

Sleep is important for several reasons. It replenishes us, boosts our health, and allows the brain and body to tidy up and prepare for the next day. During sleep, our brains replay the events of the previous day, and new experiences are compared with past recollections.

#5

The University of Pennsylvania’s renowned sleep researcher David Dinges has probably robbed more people of sleep than anyone else in the world. In one experiment, he and his team allowed some volunteers to sleep only six hours a night while others got to snooze for eight hours.

#6

The brain’s inner clock orchestrates the beautiful flow of our bodies through waking and sleep. Our most important biological rhythm is the twenty-four-hour cycle of day and night. Our circadian rhythm is controlled by the release of a sleep-inducing signal, melatonin.

#7

There are two types of sleep, REM and non-REM, which take turns controlling our brains while we sleep. When we doze off, the brain usually goes right into NREM sleep, for some well-deserved rest. About every ninety minutes, our sleep completes one cycle, passing from light sleep to deep sleep and then returning to light sleep.

#8

During stage 3, your brain waves switch from the jittering little bounces seen during waking to slow, undulating waves. These waves wash over the brain 1000 times a night, erasing memories
