Top 10 Fascinating Facts About Sleeping You Didn’t Know

7. YOU’RE PARALYZED

During REM sleep, the only active muscles are the ones moving your eyes and controlling your breathing. Though the muscle paralysis phase is only 20 to 30 minutes, it keeps you from acting out your dreams – and giving your innocent bed partner a swift kick or punch (that’s not nice.)

8. YOU’RE CHURNING OUT GROWTH HORMONES

During non-REM (NREM) sleep, our bodies will produce the hormones we need throughout life. Growth hormones, thyroid hormones, adrenocorticotropic hormones, follicle-stimulating hormones, and other types are released during sleep.

9. WE’LL SPEND 122 “DAYS” OF THE YEAR SLEEPING

Well, if you consider the average person, who (statistics show) gets somewhere around 8 hours of sleep per night, they’ll sleep the equivalent of 122 days out of the year.

10. SLEEP CAN BOOST YOUR IQ

Researchers from the Max Planck Institute in Munich, Germany found that “a good night’s sleep can do wonders for women’s intelligence.” In a study of 160 adults – 72 women and 88 men – scientists concluded the following:

“Sleep spindles, which are associated with higher IQ scores, were boosted when women entered dreamless sleep.”

– Sleep spindle activity was similar for men, but only during naps that did not exceed 100 minutes.

What does this mean? Well, for a woman, you should aim for 7-8 hours of sleep per night; for a man, you may want to consider a power nap during lunch time.
