I’m here at work again, as I seem to be every morning around this time, and I find myself so stinkin tired. It seems to only be this week though. I don’t remember being this tired… Anyway, being tired spurred this post and the desire to find some randomly fun sleep facts….
Anything less than five minutes to fall asleep at night means you’re sleep deprived. The ideal is between 10 and 15 minutes, meaning you’re still tired enough to sleep deeply, but not so exhausted you feel sleepy by day.
Dreams, once thought to occur only during REM sleep, also occur (but to a lesser extent) in non-REM sleep phases. It’s possible there may not be a single moment of our sleep when we are actually dreamless.
REM dreams are characterised by bizarre plots, but non-REM dreams are repetitive and thought-like, with little imagery – obsessively returning to a suspicion you left your mobile phone somewhere, for example. (Which is very true, you should hear some of my crazy dreams!)
The average human will spend 1/3 or their life sleeping, which equates to about 20 – 25 years over 75 Year life span
Tiny luminous rays from a digital alarm clock can be enough to disrupt the sleep cycle even if you do not fully wake. The light turns off a “neural switch” in the brain, causing levels of a key sleep chemical to decline within minutes.
As a group, 18 to 24 year-olds deprived of sleep suffer more from impaired performance than older adults.- which i fit (kind of 🙂 )
Sleep well friends!
