13 Random Sleep Facts You Just Need to Know

Odd Sleep Facts


1.) What Do My Dreams Mean? There’s not a clear cut answer and some experts argue that we dream to fix experiences in long-term memory, meaning we dream about things in our life worth remembering. Others argue the point that we dream about things worth forgetting – to eliminate overlapping memories that would otherwise clog up our brains. Like our brains are a computer and we are defragging the hard drive.

2.) Honey, It’s Your Turn. You almost always get the same answer when asking new parents how things are going. A new baby in the house, on average, results in 400-750 hours lost sleep for parents in the first year; that’s up to 2 hours of less sleep per night!

3.) In Your Dreams Buddy! In normal healthy sleep, REM sleep occurs periodically throughout the night totaling about 2 hours, usually starting about 90 minutes after you fall asleep.

4.) Random Animal Fact. Sorry, had to throw one in here. Elephants sleep standing up during non-REM sleep, but lie down during REM sleep.

5.) Out Like a Light. Sleep onset (falling asleep) in less than five minutes is an indicator that you are sleep deprived. Ideally it should take between 5-15 minutes to achieve sleep, just enough tiredness to sleep soundly, but not so exhausted you feel sleepy by day.

6.) Turn Out The Lights; The Party is Over. Seventeen hours of sustained wakefulness leads to a decrease in performance equivalent to a blood alcohol-level of 0.05%.

7.) Hey, Didn’t Kramer Have a Mental Alarm Clock?  The “mental alarm clock” which enables some people to wake up more or less when they want to is caused by a burst of the stress hormone adrenocorticotropin. Researchers state this is a reflection of unconscious anticipation of the stress of waking up.

8.) Bottoms Up! For every ounce of alcohol (spirits), REM sleep is delayed by 1 hour. A night on the “good stuff” will help you fall asleep but it will be a lighter sleep without much dreams.

9.) Rest Up for That Big Party. After five nights of partial sleep deprivation, three drinks will have the same effect on your body as six would when you’ve slept enough.

10.) Hey Duck Dynasty Fans. Did you know ducks use a technique to avoid predator attacks and are able to balance the need for sleep and survival, keeping one half of their brain awake while the other half goes into sleep mode.

11.) Come On Gentlemen; She Deserves It. Some studies suggest women need up to an extra hour of sleep per night compared to men, and not getting it may be one reason women are much more susceptible to depression than men.

12.) Did You Just Give Me The Finger? Just as some people talk in their sleep, sign language speakers have been known to sign in their sleep.

13.) Log Off Now! Experts say one of the most common sleep distractions we have today is the accessibility of the internet 24 hours a day. So Either Go Shop at 1800CPAP.COM or go to bed.
