How and Why We Sleep
It’s apparent that everyone needs to sleep. / However, most people rarely think about how and why they sleep. / We know that if we sleep well, we feel rested. / If we don’t sleep enough, we often feel tired and irritable. / It seems there are two purposes of sleep: / physical rest and emotional and psychological rest. / We need to rest our bodies and our minds, / both of which are important in order for us to be healthy. / Each night we alternate between two kinds of sleep: active sleep and passive sleep. / The passive sleep gives our body the rest and prepares us for active sleep, / in which dreaming occurs. /
Throughout the night, people alternate between passive and active sleep. / The brain rests, then it becomes active, then dreaming occurs. / The cycle is repeated several times throughout the night. / During eight hours of sleep, people dream for a total of one and half hours on the average.
