Even if you don’t eat very well, while you may be a little or very overweight, you can still expect to live around 65-75 years.
But if you don’t sleep, you’ll likely only last a few weeks at best. Last time I checked the Guinness World Record for sleep deprivation is just 11 days.
So yes, among MANY other reasons, sleep is essential to optimal health and survival. And yet, most busy professionals like celebrities, executives, entrepreneurs, athletes, and university students sleep less than ever before?
Although many of us may feel that work demands a lot of our attention or that we can’t get our brains to shut off, the real reason for lack of sleep is rarely long work hours or physiologic abnormalities. Instead, indeed most people lose sleep due to voluntary bedtime delay.
