Dolphins Sleep With One Eye Open


Sleep is a universal necessity—not just for every person, but for every animal too. But just as we all sleep differently, every species of animal is unique in the way they catch their Zzz’s. Have you ever wondered how dolphins—one of the most beloved and emotionally complex species of the animal kingdom—sleep? The answer might surprise you!

“Dolphins sleep with one eye open, because only half their brain is asleep at a time. The other half is breathing, keeping warm, and staying safe from predators. You are not a dolphin! You need eight hours of quality sleep with both eyes closed to be at your best.”

Sleeping with one eye open might work for a dolphin, but it won’t work for you.
