Sadly, people are not getting enough sleep. Charles A. Czeisler, Ph.D., M.D., the head of the Division of Sleep Medicine at the Brigham and Women’s Hospital at Harvard Medical School, believes that the world has entered a global sleep deprivation epidemic.

Why are we so sleep deprived as a society? Smartphones, tablets, and televisions create shorter wavelength lights that appear to have the ability to reset our biological clock and can even change our time zone. Bedtimes start to change every day, which leads to sleep deprivation.

Czeisler states, “When I was growing up, 2–3% of the population slept less than six hours; now it’s 10 times as many.”

He goes on to say, “We’ve increased by an order of magnitude our per capita light exposure. Take all the people who died on 9/11—twice as many die in motor vehicle crashes every year in the U.S. alone due to sleep deprivation.

“There are about 60,000 debilitating injuries on the highway [caused by under-slept drivers]. And we’re getting more overweight because we’re sleeping less. As sleep has gone down, waistlines have gone up. When you don’t get enough sleep, your brain goes into starvation mode.”

8. Does Your Phone Hinder Your Sleep?

Cell Phone

Most people sleep with their phone nearby, which might be hindering your body’s sleep-promoting neurons and the body’s natural cycle of melatonin. These things cause you to get sleepy and if you don’t have enough then you might not feel sleepy.

Most experts advise putting your phone in another room if you are having trouble sleeping.

7. Alcohol, Caffeine, and Sleep

Avoid Caffeine

Drinking alcohol or caffeine might not only make it more difficult to fall asleep but could impact your overall sleep quality. You’ll often feel anxious and depressed.
