Oh sleep As small children, we struggle to go to bed and as adults, we would do anything to squeeze an extra hour. But did you know that the dream goes far beyond affecting our state of mind?

There are extremely powerful links between loss of sleep and Alzheimer's disease … cancer … obesity … diabetes … heart attacks … strokes … and … as expected, poor health mental.

You have probably been told many times that 8 hours per 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 are receiving regularly 7 hours or less per night, then you are part of the sleep deprived population.

And things have to change.

Human beings have not evolved to survive with a reduced sleep, we simply can not handle it.

For example, even if you only sleep a bad night, your cancer-fighting cells decrease by 70%. After only one night !!!

Many accredited studies have found the same relationship: the shorter you sleep, the shorter your life.

In fact, look at how much loss of sleep costs these countries each year!

That is not something we should be ignoring.

So, why are we so sleep deprived? Have we always been like this?

Do not.
The loss of sleep is a growing epidemic that is the result of modern life.
Things like the street lights that bring light to the night …
Smart phones distract us from sleeping and shine bright lights on our faces …
longer work hours so that, to have a social life or go to the gym after work, we have to extend our days even more
The strange stigma is that the dream is for the lazy people … it is not, it is for the smartest among us!

And the wonderful thing about this? No medication is needed to solve this epidemic; we just need to educate ourselves about the importance of sleep and start programming those 8 very important hours every night.

If you need motivation to force yourself to go to bed an hour early, what do you think of these four things?

(1) Sleep can get slim … People who sleep less than 7 hours tend to gain more weight and have a higher risk of becoming obese

(2) Sleep increases mental well-being … Chronic sleep debt can lead to depression and anxiety

(3) Sleep protects against heart disease

(4) Sleep increases fertility.

So spread the word to your friends and family: 8 hours of sleep per night is the easiest medicine you can give yourself.
