If you were walking in the woods, and suddenly the path split into two different roads, which one would you choose: the one covered with grass that few people had taken or the cleared one that many others had already walked down? Anyone who has read the poet Robert Frost probably recognizes this situation from one of his most famous poems, "The Road Not Taken." After carefully considering both roads, the speaker of the poem chooses the grassy one, or "the one less traveled by." Then he says that this choice "has made all the difference."
Sleep is the time when our bodies and minds are rested and restored. There are two types of sleep: Rapid Eye Movement (REM) and Non-REM. We need both types to be healthy. REM sleep is when we dream. Our brains are active, and our eyes make fast short movements as if watching something. This type of sleep helps restore our mind. Non-REM sleep is when our brain and body slow down. Our heart rate slows and our breathing is regular. This type of sleep helps restore our body. We have twice as much Non-REM sleep as REM sleep each night.
