All about Sleep
One would never relate sleep with frenzied cerebral activity and hyper-active physiological functions.
But that's exactly what happens when you're in a deep restful slumber. So discover more interesting things about the activity that you spend a third of your life doing.
Researchers say that sleep is not a passive phenomenon but an active state, during which the brain buzzes with activity.
Eyes begin to roll back and forth, in what is known as REM (Rapid Eye Movement), blood pressure and heart rates are elevated.
Periodic twitching of the face and extremities, a relatively high level of oxygen consumption by the brain and increased blood flow to the brain are some of the activities taking place as you sleep.
