10 great people who slept less than five hours per day
Many famous people, especially politicians and ingenious inventors, slept very little. Partly, due to the amount of work they had, partly because they practised polyphasic sleep routine trying not to waste too much time sleeping. Today you will learn about the most outstanding practitioners of this polyphasic sleep and what they achieved thanks to it.
External information is selectively suppressed during REM sleep phase
In general, it is believed that sleep leads to a disconnection of a person from the outside world. However, it has not yet been precisely determined what happens during the REM sleep phase - processing of external signals or their suppression. A group of French scientists decided to find out by using 18 participants for the experiment.
The brain replays the wakefulness experience during sleep — direct evidence
Our brain does not go into “standby” mode during sleep — it organizes new long-term memories. By now, scientists have received reliable evidence that the replication of the experience gained on the eve continues during rest as well. For this, microelectrodes were used, and signals were received from two volunteers as part of a clinical trial of the “brain-computer” interface, designed for people with disabilities.
Students learned better by listening to classical music during lectures and sleep
Researchers at Baylor University shared the results of an interesting experiment. Classical melodies were played twice for one (test) group during an interactive lecture on microeconomics and during sleep. Another group just listened to the lecture and slept with white noise in the background. The next day, the "musical group" showed better results in testing the material learned the day before.
