(CNN) -- Did you get a good night's sleep? If you're like a third of American workers, you didn't.
The CDC says nearly 41-million workers sleep fewer than six hours a day.
The people who work nights are more likely to sleep less.
Health officials say this puts people at risk for serious and sometimes deadly situations.
The National Sleep Foundation recommends adults sleep seven to nine hours a night.
Over time, not getting enough sleep can cause cardiovascular problems, obesity, diabetes and depression.
