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.
