One account documents the process by which a solo sailor broke his sleep into between 6 and 7 naps per day. You can’t sleep for one hour, then two hours, and combine it with another four hours and say it’s seven hours,” Avidan says. Polyphasic sleep schedule: These sleepers break down their sleeping into small portions, usually four to six episodes of sleep in a 24-hour period. Even if this pattern might sound completely crazy to you, when you think about it, polyphasic sleep is quite widespread in animals. Experts recommend that adults should have a sleep schedule of about 7-9 hours per day. This can interrupt a person’s sleep-wake cycle and have a negative impact on their sleep durations. Can polyphasic sleep pattern harm health? Historian A. Roger Ekirch has argued that before the Industrial Revolution, interrupted sleep was dominant in Western civilization. He would go to bed from 6 am – 9 am and 3.30 pm – 7.30 pm. Monophasic sleep is what today’s society would refer to as a “normal” sleeping pattern. No matter how much you decide to sleep, maintaining a constant sleeping pattern will help you reach your highest wake-time potential. There are three types of most common sleep patterns: While the monophasic sleep pattern represents a “normal” sleep-wake cycle where an individual sleeps once per day for about 8 hours, the biphasic pattern is when a person sleeps twice per day. The term polyphasic sleep is also used by an online community that experiments with alternative sleeping schedules to achieve more wake time and/or better sleep each day. Polyphasic sleepers, meanwhile, snooze in short bursts throughout the day instead of sleeping all night. Nowadays, the definition of polyphasic sleep is any sleep schedule with at least two sleeps per day, to distinguish it from monophasic sleep, which only has one sleep per day. According to Ekirch's argument, adults typically slept in two distinct phases, bridged by an intervening period of wakefulness of approximately one hour. Some literature and research suggests that humans are naturally polyphasic sleepers. People have an internal circadian rhythm, a routine of biological and behavioral processes that roughly occur every day over a 24-hour cycle. The short article about Fuller's nap schedule in Time in 1943, which referred to the schedule as "intermittent sleeping", says that he maintained it for two years, and notes that "he had to quit because his schedule conflicted with that of his business associates, who insisted on sleeping like other men. It purportedly shows that all stages of sleep were included. Get this exclusive e-book now! The term polyphasic sleep was first used in the early 20th century by psychologist J. S. Szymanski, who observed daily fluctuations in activity patterns (see Stampi 1992). Studies have shown that people who work the night shift tend to have more health issues, such as heart problems and shorter lifespans, than people who work during the day. And what works for a person A, doesn’t necessarily have to work for a person B. Many polyphasic sleepers believe the other phases of the sleep cycle are unnecessary, and that by eliminating them, they can spend more productive hours awake. “Sleep is not like a bank account. You will feel tired, but then after 3-5 days your brain will rewire and will start readjusting to the new sleeping pattern. This meant that a person would sleep in two segments of time throughout the night with a waking period of about one to two hours in between. POLYPHASIC SLEEP MASTERY. However, the best polyphasic sleep type is the free running sleep, in which you just follow what your body tells you, and don’t sleep more than your body needs it. First, it’s important to understand how the three different sleep pattern classifications differ. The human circadian rhythm regulates the human sleep-wake cycle of wakefulness during the day and sleep at night. Different cultures strive to maintain good sleep hygiene in different ways. One theory put forward by historian Roger Ekirch is that before industrialization in the world, it was normal for people to have what was called first and second sleep.
