IS IT TRUE THAT WE ALL HAVE A ‘SLEEP ANIMAL’?
ESME NEWMAN, VIA EMAIL
Have you taken one of those online quizzes that assigns you an animal based on your sleeping style? According to some, there are four types of sleep animal: wolf, lion, bear and dolphin. But in 2022, Fitbit introduced sleep profiles that identified users as giraffes, bears, dolphins, hedgehogs, parrots or tortoises.
These animals don’t seem to relate to the sleeping habits of the people they’re assigned to – unless those ‘dolphin’ sleepers only allow half of their brains to sleep at any one time, as the mammals do in the wild. You won’t find any of those sleep animals in the scientific literature, though. Only two are generally accepted by the scientists: morning larks and night owls.
