What happens when we don't get enough sleep?
Day to day, it leads to irritability, cognitive problems, and difficulty concentrating. Being sleep deprived affects every part of our psyche. We become irritable, and less able to deal with problems as they come about, leading to anxiety and depression. Scientists and doctors have done studies where they have run tests on subjects that were sleep deprived, and their alertness was affected dramatically. But when they were interviewed, they said they got used to their shortened sleep schedule, and felt fine. In reality, their concentration was suffering drastically. A lack of sleep will definitely affect your ability in the workplace.
Are Americans getting enough sleep? Can naps help offset that?
No, we aren't. As a society we are getting on average an hour less of sleep than we were one hundred years ago. Which is a significant amount. We need about seven to eight hours a night, and most people aren't getting that. A daily nap can offset some of that lack of sleep.
