Falling asleep

All people need sleep at night and at day. No matter when you need this sleep but the main thing is that you need it, one way or another. It is a rest you have while sleeping and it is the necessary rest. You know, that rest you have while sleeping is a rest necessary for your brain and it is your brain that makes you fall asleep. There are such cells in your brain that are like safety devices. At least that is how those operate. See, you have those thoughts on your head and you receive the whole information during a day and that whole stuff is processed in your brain and that is why brain gets tired. Brain gets tired and it needs rest because otherwise something bad may happen. In case you never give a rest for your brain then it takes it himself. Those safety cells direct an order for your whole body to fall asleep and you feel tired and sleepy. In other words, your brain (that controls your whole body) orders you to fall asleep and you follow this order. That is how it happens and the reason for it is that you need rest and your body needs rest.
