#17: Sleep is Bloody Remarkable #1

Series Intro

Matthew Walker introduces his new series, 'Sleep is Bloody Remarkable,' where he shares mind-blowing facts about sleep. He starts with the phenomenon of half-brain sleep, also known as unihemispheric sleep, where one hemisphere of the brain remains awake while the other sleeps. This remarkable ability is seen in cetaceans like dolphins and whales, which need to stay alert to maintain necessary movement in their aquatic environment 1.

In this episode, Walker delves into the specifics of half-brain sleep, explaining how it allows one side of the brain to rest while the other stays fully awake. He highlights that this phenomenon is not unique to aquatic mammals but is also observed in birds, which use it for survival purposes. Walker's fascination with sleep is evident as he describes the intricate balance between the two hemispheres of the brain during unihemispheric sleep 1.
