Sleepy? CDC says 1 in 3 Americans don't get enough shut-eye

Just as Americans are set to spring forward this weekend and lose an hour of sleep, a recent study is highlighting the fact the most of us aren't getting enough shut eye.

The Centers for Disease Control and Prevention says a lack of sleep puts Americans at a higher risk of obesity, heart disease and other issues.

CDC experts looked at health surveys covering more than 400,000 Americans. They were asked how many hours of sleep they get each night, among other questions.

On average, only 65 percent said they get seven hours or more of sleep a night, the team reported.

Sleep expert Dr. Michael Breus says the most common obstacle to sleeping well is stress.

"One of the biggest things my patients tell me is they can't turn off their brain at night, and that can have a pretty big effect on your ability to not only fall asleep, but to get into deep sleep," Breus said.

Other factors that could impact the quality of sleep are not having the right mattress, sheet, pillow or lighting, and sound can interrupt sleep.

Drinking caffeine and alcohol too close to bedtime can also have an impact.

The best bet for good sleep is going to bed and waking up the same time every day.

"The more consistent you are with that, the more your brain knows when to sleep," Breus said.
