I don't know about you, but I'm getting tired of sleeping. Is this thing on? All right. Never mind. Spending one-third of my day unconscious seems like a waste of time. And while sleep is thought to play a role in health, memory and learning, do we need so much of it? What if we instead only took naps? I mean everybody loves naps, right? Over 85% of mammals are biphasic sleepers--meaning they sleep in several short periods throughout the day. As opposed to monophasic sleepers like most humans, who load up on their sleep just once a day. Naps are typically defined as a shortened period of sleep up to 90 minutes. A 20 minute nap improves your alertness and mood without making you feel disoriented because you stay in the lightest sleeping stage. While a longer nap lasting 30 minutes to an hour will get you into the deeper sleeping stages, leaving you with a feeling of sluggishness when you wake up. This is called sleep inertia. But if you have time for a 90 minute snooze, you will cycle through the deepest sleep stage and back again, leaving you feeling revitalized with a memory and creativity boost! Studies have also shown that naps can increase your attention span, improve your overall performance, and help with depression. Some people believe that they can survive purely on naps alone, giving them more waking hours for productivity. These polyphasic sleepers claim that they can adjust their body to enter REM sleep immediately, eliminating the need for a long period of sleep. There are three main polyphasic sleep schedules. The Everyman cycle is the least severe and includes one long sleep period at night for about three hours, with three 20 minute naps over the day. The Uberman cycle includes a 20-30 minute nap every four hours, which makes six naps totaling about 2.5 hours of sleep a day. And the Dymaxion cycle includes just four naps lasting 30 minutes each, resulting in just two hours of sleep! Since not many people could sustain this kind of sleep pattern--except for maybe Ronbus over here! He's a partier! There is limited information on the effects it has on the body. However, proponents of these sleep schedules claim that they feel great and have reported no health issues. In the late 80's, a neurologist and sleep expert named Claudio Stampi studied the effects of polyphasic sleep schedules on yachtsmen racing across the Atlantic ocean. He found that the fastest sailors slept less and in shorter episodes, for an average total of 5 hours a day in 1.3 hour bursts, indicating that it's possible to adapt to getting just 60-70% of your usual sleep amount without a significant impairment on performance. However, this study based its findings purely on the results of the races and did not directly evaluate their mental capacity, how their health was affected, or any long term effects. Generally, sleep deprivation can make you irritable, slow your reaction time, increase anxiety, and even affect your ability to form memories. And studies have found that people who drive while sleep deprived are just as dangerous as drunk drivers. So, while clicking on the next video may be tempting, I think it's time to get some sleep. Unless you have already gotten plenty of sleep in which case please feel free to click on the next video. So do you think that you could survive on just naps alone? Are you a person who likes taking naps? Let me know in the comment section below. Curious to know how you could live for an extra 100 years? Check out this video! Researchers found a type of molecule that may reverse aspects of the aging process. Sure their experiment was conducted with mice, but it's still a step in the right direction. As always, my name is Blocko, this has been Life Noggin, don't forget to keep on thinking!
