Can you be awake and asleep at the same time? | Masako Tamaki

The video explores asymmetrical sleep, where one brain hemisphere is more active than the other. This phenomenon is observed in various animals, including dolphins, seals, and birds, allowing them to remain alert while resting. Dolphins and seals use unihemispheric sleep to continue swimming and breathing. Birds, like frigatebirds, sleep during long migrations. The benefits of asymmetrical sleep vary across species. In humans, a subtle form of asymmetrical sleep occurs during the first night in a new place, enhancing vigilance. This adaptation helps animals and humans stay alert to potential threats.
