Many people believe that when they sleep, their brain sleep as well. Actually, the brain is very active during sleep. Beside it does standard processes, it prepares your body for the future actions, it creates memories and make older memories easier for retrieval. A research at the University of Rochester, found that during sleep, our brain is ‘’cleaning’’ our body. We remove toxins and dangerous substances. Some of toxins that our body must eliminate can contribute to neurodegeneration.

Scientists proved that people who get up early in the morning, had trimmer waistlines and their motivation is very high. Also, those people exercise a lot more than people who don’t get up early in the morning. One study found that morning people had more positive feelings.
