Sleep Patterns

Sleeping is one of Ernest’s favourite pastimes. However, it’s also a remarkable period of synchronised brain activity, memory consolidation and maintenance. Scientists are still trying to understand the nuances of sleep patterns and the variety of schedules humans can sustain.

Monophasic

In 1938, Nathaniel Kleitman journeyed 128 feet below the earth’s surface to redefine the day. Although he couldn’t adjust to his 28-hour cycle, his research furthered our understanding of the most common monophasic sleep pattern, the 7 to 9 hours of sleep we crave nightly. Interestingly, this sleeping schedule came into vogue during the propagation of coffee houses.

Biphasic

Pre 18th century, people would regularly don their nightcaps twice in one night. Historian Roger Ekirch suggests that a ‘first’ and ‘second’ sleep was commonplace practice. One French physician even noted that conception was more likely between these phases of sleep. In the modern day, biphasic sleeping still exists in many parts of Europe, commonly known as the humble siesta.

Polyphasic

Referring to more than two periods of sleep in a 24-hour cycle, polyphasic sleep might not be for everybody. Dr. Yung-Hui Fu suggests only a small percentage of people can adapt to these conditions; due to a rare mutation of gene DEC2, it is possible for the brain to perform maintenance much faster during sleep than the average human.

Dymaxion

Many have explored the possibilities of polyphasic sleeping practices. Inventor and philosopher Buckminster Fuller created his own Dymaxion schedule, consisting of a 30-minute nap every 6 hours. ‘2 hours of sleep a day is plenty’ he once said in an interview with Time magazine. Fuller later abandoned the schedule after coming into conflict with his colleagues and wife.

Uberman

A modern day attempt at a polyphasic sleep pattern, the Uberman (after Friedrich Nietzsche’s ‘Übermensch’) is a schedule created by Marie Staver, involving 20-minute naps every 4 hours. In the early phases, Staver carried a stack of dishes around her dorm to make sure she didn’t fall asleep by accident. She has since developed the ability to sleep standing upright.
