First and foremost, sleep has a direct impact on your brain. It means that the time of sleep determines the way you think and how you feel the next day after you wake up. It can impact you by making you nervous, and unconfident. It will make you feel like everything you are doing is not good enough and you might be angry at every small thing that people around you do.
For instance, a student is waking up in the morning after having fun at a party the night before. That student is nervous and will fail on the exam he has that day. After he comes back home he yells at his mother just because she asked him about his day at the high school.
Well, in this case, that student has to think about the time of sleep he has nor he will keep feeling that bad.
According to recent studies, people with less sleeping hours are less communicative than those who slept well. When you don't sleep enough it will be hard for you to pay attention to everything which is going on around you. People will talk to you but you won't listen to them at all, which can really hurt them sometimes. It can actually make other people not to want to be around you, and it will be hard to change it the next day.
