Description

Please note: This is a companion version & not the original book.
Sample Book Insights:
#1 Our treatment of sleep today is brutish. We, on average, sleep about 7 hours a night, with 5 percent sleeping fewer than 5 hours and 6 percent sleeping more than 9 hours. By contrast, some historical reports suggest that we slept significantly longer in the past.
#2 We sleep less now than we did at any other point in history. This is likely due to the culture of long work hours, shift work, long commutes, global communication across multiple time zones, and freedom from many economic and social constraints.
#3 Sleep has been studied for at least 2,500 years, and the Greeks philosophers Alcmaeon, Hippocrates, and Aristotle all put forward theories on the causes and functions of sleep. The idea that the brain was central to sleep was developed at the start of the 19th century with experiments on birds by Luigi Rolando and later by Jean Pierre Flourens.
#4 The science of sleep was advanced by the ability to measure brain activity during sleep, which was first done in 1939. The first laboratory dedicated to sleep was established in 1925 at the University of Chicago by Russian researcher Nathaniel Kleitman.

#1

Our treatment of sleep today is brutish. We, on average, sleep about 7 hours a night, with 5 percent sleeping fewer than 5 hours and 6 percent sleeping more than 9 hours. By contrast, some historical reports suggest that we slept significantly longer in the past.

#2

We sleep less now than we did at any other point in history. This is likely due to the culture of long work hours, shift work, long commutes, global communication across multiple time zones, and freedom from many economic and social constraints.

#3

Sleep has been studied for at least 2,500 years, and the Greeks philosophers Alcmaeon, Hippocrates, and Aristotle all put forward theories on the causes and functions of sleep. The idea that the brain was central to sleep was developed at the start of the 19th century with experiments on birds by Luigi Rolando and later by Jean Pierre Flourens.

#4

The science of sleep was advanced by the ability to measure brain activity during sleep, which was first done in 1939. The first laboratory dedicated to sleep was established in 1925 at the University of Chicago by Russian researcher Nathaniel Kleitman.
Insights from Chapter 2

#1

There are two types of sleep: rapid eye movement and non-rapid eye movement. They alternate to form a NREM–REM sleep cycle about every 90 to 100 minutes. During REM sleep, the beta EEG patterns are almost identical to those measured in a fully awake individual.

#2

The human body goes through cycles of NREM and REM sleep. NREM sleep is more stable, and is typically associated with regular breathing and lower heart rate. REM sleep is more active, and is usually accompanied by rapid eye movements.

#3

Dreams are very variable, and they usually involve the dreamer and people who are familiar to them. They are almost always visual experiences, and rarely involve taste or smell.

#4

REM sleep is when we have nocturnal erections and clitoral engorgement. There is no evidence that sexual activity before or after sleep affects the level of penile tumescence.

#5

The two-process model of sleep regulation is a useful way to think about sleep-wake timing. It suggests that two oscillators contribute to sleep, an hourglass-like sleep–wake counter and an internal 24-hour circadian rhythm of sleep and arousal. They interact to determine the timing, duration, and structure of sleep.

#6

The two processes, Process S and Process C, can interact to cause a dramatic increase in sleepiness. This occurs under certain circumstances, and is especially dangerous for shift workers, doctors, firefighters, and other professionals who must be alert during normal sleeping hours.
