Quirky, weird and interesting sleep trivia

Why do we sleep? It might sound like a silly question, but the truth is that even scientists don’t know all the reasons we sleep. Considering how much time humans spend sleeping, it’s surprising (to us at least) that most of we know about sleep has been learned in the last 30 years.

Curious about sleep? Dig into some odd & quirky sleep facts!

  • Humans are the only mammal that willingly delays sleep.
  • Whales and dolphins never fully fall asleep. Half their brain always stays awake so they can continue to surface breathe.
  • Tony Wright claims to hold the world record for sleep deprivation, staying awake for 266 hours in 2007. The Guinness Book of World Records rejected his claim (and all claims on sleep deprivation after 1990) due to possible health risks (including death).
  • Our minds incorporate sounds and smells around us when we’re dreaming. If you’re napping while someone’s cooking lasagna, you might start dreaming you’re dining at an Italian restaurant.
  • According to the Centers for Disease Prevention and Control (CDC), more than 30% of adults (over 18) and 72% of students (grades 9-12) get insufficient sleep on a regular basis. What’s more, 4% of Americans use prescription sleep aids, with the drug being more commonly used among women and older adults.
  • Everyone dreams 4 to 7 times each and every night. Everyone. If you can’t remember your dreams, you’re not alone. Most people forget 90% of their dreams – usually within the first 5 minutes of waking up.  Quirky, weird & interesting sleep trivia
  • Do blind people dream? “When you’re asleep, your brain processes the experiences you’ve had while awake and builds dreams out of them. If you can see, your dreams contain a number of images and visual memories; if you can’t see, your dreams contain more sounds and tactile experiences. For example, a sighted person dreaming about the beach probably sees the sand and the ocean, and a blind person dreams about the breaking of the waves, the smell of the ocean and the feeling of sand between his or her toes,” according to Discovery.com.
  • Somniphobia is the fear of sleep.
  • The human body never adjusts to shift work and people who alternate shifts over a long period are at increased risk of chronic illnesses, such as cardiovascular and gastrointestinal diseases.
  • Waking up multiple times during the night is normal. Some studies suggest we wake up as many as 8 times throughout the night as we cycle between light, deep and REM sleep.
  • Our dreams don’t create faces – we dream about what we’ve already seen (if only for a second).
  • More than 80% of people under 30 dream in color but just over 10% of people dream entirely in black and white their whole lives.
  • Giraffes only need two hours of sleep each night where as a bat sleeps for almost 20 hours at a time.
  • Humans spend a third of our lives asleep while cats spend two thirds of their lives asleep. Cats are our spirit animal!
  • Falling asleep takes an average of 10-20 minutes. Falling asleep too quickly may be a sign of sleep deprivation.
  • Dreams are can be an emotional rollercoaster, cycling through your feelings of the past day. The most common emotion is anxiety, which begs the question – why are we all so stressed?
  • Pulling an all-nighter to finish a report or study for an exam? Not sleeping for 16 hours can make you behave as if you have a blood alcohol level of .05%.
  • Throughout an average night, you’ll cycle into deep REM sleep approximately every 90 minutes. At each point, a burst of electrical activity streams through your brain, which is also the time you’re most likely to dream.
  • If you live to be 75 years old, you’ll have spent approximately 25 years sleep – 6 of those years will be jam-packed with dreams.
  • Ever fall asleep and wake up with a sudden jolt seconds later. That action is called a myoclonic jerk.
  • Blind people often struggle with sleep because they have no perception of light. Their circadian rhythm (internal clock) lacks the ability to match up a night and day cycle.
  • Full moon? Some studies suggest that the full moon robs us of a good night’s sleep. Even if you sleep in a windowless room free of environmental and time-based cues, (such as those found in a sleep lab) your sleep is likely to be shorter and interrupted more, according to ScientificAmerican.com.
  • How much sleep do you need? Studies show that people who sleep between 6.5 hr. and 7.5 hr. a night, live the longest. People who sleep more than 8 hr. or less than 6.5 hr. don’t live quite as long. Read more at Time.com.

Getting a good night’s sleep can become an overwhelming stress if it’s out of reach. And lack of sleep could be a sign that there’s something else (medically) going on – which means it’s time for professional help. Don’t hesitate to contact a sleep doctor if you’re concerned.
