Some you may know, others may surprise you
It’s a known fact that humans spend 1/3 of their life sleeping and yet the value of sleep quality and quantity is often not considered in our day to day lives. When last did your doctor/ physician/health practitioner ask about your sleep?
Here are some interesting facts about sleep:
- A study found that 12% of people dream entirely in black and white
- The record for the longest period without sleep is 11 days – this was set by a Californian student named Randy Gardner in 1964
- It’s not uncommon for deaf people to use sign language in their sleep
- It’s thought that up to 15% of the population are sleepwalkers
- 1 in 4 married couples sleep in separate beds
- Sleep deprivation will kill you more quickly than food deprivation
- Amnesty International lists sleep deprivation as a form of torture
- Within 5 minutes of waking up, 50% of your dream is forgotten
- Tolerance for pain is reduced by sleep deprivation
- High earners (R1, 000,000.00 pa) get the best sleep
- Snoring is a primary cause of sleep disruption
- People can take cat naps with their eyes open without even knowing it
- People who don’t get enough sleep are more likely to eat more because of their leptin levels (appetite-regulating hormone) dropping, promoting appetite increase
And in the animal kingdom
- Scientists don’t know if animals dream during REM sleep, as humans do
- Two thirds of a cat’s life is spent asleep
- A giraffe only needs 1.9 hours of sleep a day, whereas a brown bat needs 19.9 hours a day
