She says the new study does show that people may sleep for a surprisingly short time for primates. Isabella Capellini is an evolutionary biologist at the University of Hull in England. “But something had to give as we slept less.” “It’s pretty surprising that non-REM sleep time is so low in humans,” Nunn says. And it has been linked to learning and memory. That has left less time for sleep.Īs sleep declined, rapid-eye movement - or REM - sleep took on an outsize role in humans, Nunn and Samson propose. The second may reflect the intense pressure humans face to learn and teach new skills and to make social connections. At that point, people probably had to spend more time awake to guard against predators. The first stems from when humans’ ancestors descended from the trees to sleep on the ground. The researchers argue that two long-standing features of human life may play into our short sleep times. Nunn and Samson shared their findings online February 14 in the American Journal of Physical Anthropology. Most other primates in the study typically sleep as much as the scientists predicted they should. Humans averaged just seven hours of shut-eye.īased on lifestyle and biological factors, however, people should get 9.55 hours, Nunn and Samson calculate. Most species slept between nine and 15 hours daily. In their new study, the two compared sleep patterns in 30 different species of primates, including humans. Samson works at the University of Toronto Mississauga in Canada. Nunn works at Duke University in Durham, N.C. They study how humans have evolved to behave the way we do. People have evolved to sleep much less than chimps, baboons or any other primate studied so far, a new study finds.Ĭharles Nunn and David Samson are evolutionary anthropologists. We hear his mother’s voice off-camera say “Pierce wake up! Pierce! Well, I guess it speaks for itself.If it seems like you’re not getting enough sleep, you’re not alone. The video continues to show kids hugging and dancing with their Pillow Pets, until the last frame of the video which shows Pierce, who is still sleeping soundly on his Jumbo Eeyore Pillow Pet. It’s for you! It’s a Pillow Pet! Not for the pets, either. ![]() ![]() Third kid’s response: “Nobody likes sleeping, but this just makes me want to sleep.”įourth kid’s response: “Whenever I want to go on a car trip, I always ask if I can bring my unicorn because she’s so fluffy, and I can always nap on her whenever I want.”įifth kid’s response: “It’s not a parent pillow, ok? So don’t let your parents use it. Second kid’s response: “I always snuggle with her because I’m always so scared of the dark, so I’m always like.” and the little girl gives the Pillow Pet a huge hug.” Second question: How do Pillow Pets help you sleep?įirst kid’s response: “It’s very cozy, so it just reminds me of home.” Pierce is currently snoozing on a Pillow Pet and has decided to answer our questions at a later time. Third kid’s response: “They’re soft, portable, cleanable! They keep memories, not stains! So if I got a stain on it, just pop it in the washing machine, and then boom it’s ready.”įourth kid’s response: “I would be able to just fold it up and store it really easily in, like, my backpack or my suitcase.”įifth kid’s response: Actually, Pierce can’t respond. It's a Pillow Pet! It has silky soft plush fabric.” Second kid’s response: “It’s not one of those regular pillows. This video asks a group of kids several questions about Pillow Pets.įirst question: Why is everyone raving about Pillow Pets?įirst kid’s response: “So a Pillow Pet is almost like a pet, except you can also use it as a pillow.” Pillow Pets! “It’s a Pillow, It’s a Pet, It’s a Pillow Pet!” ![]()
