Every night, we spend about 8 hours sleeping. When we sleep, our bodies and brains are not really “off”. But why do we need it? We know that sleep helps us rest. It makes our brains work well the next day. If we don’t sleep enough, we will feel tired and can’t study well. I think it is worth exploring because everyone sleeps, but not many people know the real reasons. By studying sleep, we can keep healthy and live better lives. Thank you for listening! e.g. 1.
