How to get enough sleep in four hours?

You need 20 minutes of sleep every 4 hours. This thing is called polyphasic sleep.

He conducts experiments on himself. And posts them on his channel Biohacker: preps for exams in a conscious dream, learns a new language in 3 days and sure he will live 100 years.
