Sleep facts 101 – and some foolish sleep myths debunked
Sleep plays a crucial part in our lives and although we spend a lot of time doing it (1/3 of our lives) it’s shocking how little we know about it. And while most of us cherish crawling into bed after a long day, we do it differently around the world. Get ready for some fun learning!
10 fascinating facts about sleep
- Babies steal 1,055 hours from their parents. According to research, new parents lose an average of 44 days of sleep per year from their beautiful, sleepless newborn. No wonder new parents are always tired!
- Humans can sleep with their eyes open. Yes, you can sleep with your eyes open. Micro-sleeps can last 4-5 seconds, which doesn’t seem like a long time – but it’s long enough to cross the centerline on the highway and crash. Driving tired is as dangerous as driving drunk.
- Altitude disrupts sleep. Due to lower amounts of oxygen at altitudes of 13,200 feet or higher, it’s much harder to get your snooze on. Be careful next time you’re visiting the Rocky Mountains.
- Some people dream in black and white. Studies show only 12% of people dream in black and white. Surprisingly, this number was 75% before the evolution of color televisions.
- Humans are the only mammal that can delay sleep. Dogs, cows and even sheep must go to sleep when their body tells them to. We have the ability to defer sleep (to a limit, of course) and finish doing what’s capturing our attention at the moment.
- 11 days is the record for the longest period without sleep. In 1964, Randy Gardner fought exhaustion and suffered extreme sleep deprivation after his feat. We definitely don’t recommend trying this – in 2012, a Chinese man died from staying awake 11 days to watch soccer. No thanks!
- It’s common for the deaf to sign in their sleep. Just like talking in your sleep, the hearing impaired communicate via sign language while sleeping. There are many recorded instances of people who have reported seeing their deaf partner or child signing while snoozing.
- You can’t sneeze while sleeping. Humans aren’t prone to sneezing while asleep, and since we aren’t moving to stir up dust particles, the reaction doesn’t occur.
- The strangers in your dreams aren’t strangers. You might know some of them personally, but you’ve seen everyone in your dreams Crazy, right? The brain can’t create people, so it uses registered faces to populate your dreams.
- You grow .3 inches while sleeping. But the growth is temporary as you shrink back down to normal after you’re awake for a few hours. When you sit or stand, your cartilage discs are squeezed by gravity, like sponges.

Many parents believe that the cold air is healthy for children.
