Infographic: 4 alternative sleeping cycles
It is known that nights are made for sleeping and daytimes for being awake. According to one’s age, requisite sleeping hours differ. For preschoolers, 10 to 13 hours of sleep per day are necessary, for school-aged children nine to 11 hours. While teenagers need eight to 10 hours of sleep, seven to nine hours are enough for young adults.
What is obvious is that no one is getting the required amount of sleep, whether it be due to exams, work or stress. But getting enough sleep is very important to function normally during the day. Lack of sleep can generate serious problems, including a decrease in the concentration and attention.
The standard sleeping cycle is the one that has no naps; it consists of one sleep at night for seven to nine hours. If it is standard, that does not mean that it is the most efficient. For example, the standard sleep cycle cannot work for people who work during night time. It is the monophasic cycle.
The four alternative sleep cycles are called polyphasic cycles, consisting of several phases of sleep.
Biphasic cycle. The sleeping pattern is divided in two periods: the first one of five to six hours during the night, and the second one is a nap of one hour and a half during the day. This cycle improves memory and cognitive functions, allowing the body and mind to rest in order to operate better.
Everyman cycle. This cycle consists of three-and-a-half hours of sleep, along with three naps of 20 minutes during the day. It is efficient for people who want to increase their waking hours, but has downsides like getting a total of 4 and a half hours of sleep per day, only.
Dymaxion cycle. The sleeping pattern is in a form of four naps during the day, each of 30 minutes; a total of two hours of sleep per day. This one is the most difficult sleeping cycle to adapt to, but it is good for those who are considered “short sleepers” and do not require many sleeping hours.
Uberman cycle. This cycle consists of six to eight naps per day, each of 20 minutes. It is a rigid, difficult and impractical cycle, especially, that the person would be sleepy whenever there is an activity lasting more than three-and-a-half hours.
