As toddlers we fight going to bed and as adults we’d do anything to squeeze an extra hour in. But did you know that sleep goes much further than just affecting our mood? There are extremely powerful links between sleep loss and Alzheimer’s disease… cancer… obesity… diabetes… heart attacks…. strokes… and… unsurprisingly, poor mental health. You’ve probably been told many times that 8 hours a night is the recommended amount… but what do you think counts as sleep deprivation? 5 hours? 4 hours? You may be surprised to hear that anything less than 7 hours (!!!) is a lack of sleep. If you’re regularly getting 7 or less hours a night, then you’re part of the sleep deprived population. And things have to change. Humans haven’t evolved to survive on reduced sleep, we just can’t handle it. For example, even if you have just one bad night’s sleep, your bodies cancer fighting cells drop by 70%. After just one night!!! Many reputable studies have found the same relationship: the shorter you sleep, the shorter your life. In fact, look at how much sleep loss costs these countries each year!!! That’s not something we should be ignoring. So why are we so sleep-deprived? Have we always been like this? No. Sleep loss is a growing epidemic that is a result of modern day living. Things like street lights bringing light into the night… smart phones distracting us from sleeping and shining bright lights into our faces… longer working hours so that to still have a social life or go to the gym after work, we need to stretch our days even longer The bizarre stigma is that sleep is for lazy people… it’s not - it’s for the clever ones amongst us! And the wonderful thing about this? No medicine is needed to solve this epidemic; we simply need to educate ourselves about the importance of sleep, and start scheduling that very important 8 hours every night. If you need motivation to force yourself to go to bed an hour earlier, how about these four things… (1) Sleep can slim you… People who sleep less than 7 hours tend to gain weight more, and have higher risk of becoming obese (2) Sleep boosts mental well-being… Chronic sleep debt may lead to depression and anxiety (3) Sleep wards off heart disease (4) Sleep increases fertility So spread the word to your friends and families: 8 hours of sleep a night is the easiest medicine you can give yourself.
