Although I’ve already written a brief post on the sleep cycle there was a lot more that could be said on the subject. I believe it is helpful to understand how we sleep, as all other information about how to improve sleep must be based on it.
There are two major types of sleep: Non-REM, or quiet sleep; and REM, or dreaming sleep. REM, you may recall, stands for ‘rapid eye movement’ and refers to the rapid movements the eyes make while in that stage of sleep.
These two types, or categories, of sleep are radically different from one another. It is a common misconception that when we are asleep our minds and bodies are simply ‘turned off’, and when we are awake they are ‘turned on’. In reality sleep is not so passive as you may think. Our bodies, and especially our minds are busy during sleep, and they are busy doing things that they only do while asleep – things that are necessary for health and growth.
