When we don’t get enough sleep your body malfunctions, and also your brain. When you don’t sleep, first of all your body feels exhausted, and tiring. Next, it can hurt your brain because your brain always needs rest. If it doesn’t, it can not properly function, and doesn’t work that well either during school or daily life. This is another interesting fact I noticed and heard about. When you don’t sleep, your skin can get worse. Your skin needs to rest too as the rest of your body, so if you don’t, it can lead to breakouts, dry skin, baggy eyes, etc. Hope this helped!
