What happens if a person does not sleep?

24 hours later

The paradox starts with the fact that instead of feeling tired, you have a sudden burst of energy and may feel even more productive than usual. All of your senses get sharpened and the world and the people around you seem pleasant. This is because your brain is trying to compensate for the lack of sleep by increasing dopamine levels. That’s it for the good news, because if you go without sleeping beyond this point, you start facing far less exciting consequences.
