This Guy Slept For Only 5 Hours A Day As An Experiment

Do you actually need 7–8 hours of sleep every night? One man sought to find out.

If you're like most of the population, you probably sleep in what's called a "monophasic pattern," which means you do all your sleeping in one 7- to 8-hour chunk. But what would happen if you slept in shorter, naplike phases? I decided to find out:

One of the more controversial forms of polyphasic sleeping is the "Uberman schedule," where people sleep for six 20-minute naps throughout the day. This cuts their sleep time down to two hours.


I decided to follow the same sleep schedule as Jackson, which is called the "Everyman." This schedule allows you 4.5 hours of sleep at night, and two 20-minute naps during the day. This means I will get a little over five hours of sleep a day.


Dr. Avidan warned me of the short-term effects, like slower reaction time, memory problems, cognitive problems, lack of creativity, and increased irritability.

Overall, was it an experience I would recommend? Definitely not. Maybe for some people, who are genetically designed to sleep this way, it would work. But for the majority, a good 7–8 hours is where it's at.
