Sleep

The 2011 Sleep in America® poll released today by the National Sleep Foundation (NSF) finds pervasive use of communications technology in the hour before bed. It also finds that a significant number of Americans aren't getting the sleep they say they need and are searching for ways to cope.

Many Americans report dissatisfaction with their sleep during the week. The poll found that 43% of Americans between the ages of 13 and 64 say they rarely or never get a good night's sleep on weeknights. More than half (60%) say that they experience a sleep problem every night or almost every night....

About two-thirds (63%) of Americans say their sleep needs are not being met during the week.

Four out of five people say that they suffer from sleep problems at least once a week and wake up feeling exhausted....
People who get less than seven hours of sleep a night are more likely to have chronic health problems like obesity, heart disease, diabetes, high blood pressure, stroke, depression and premature death....
A tired brain is not a wise brain, and people who are sleep deprived make more mistakes.

The Centers for Disease Control and Prevention have called sleep deprivation a public health crisis, saying that one-third of adults don’t get enough sleep. Some 80 percent of people report sleep problems at least once per week, and according to a 2016 study, sleep deprivation “causes more than $400 billion in economic losses annually in the United States and results in 1.23 million lost days of work each year.”
If that’s not enough, here is a non-comprehensive list of the ways your sleep deprivation is personally harming you:

Your overall cognitive performance — particularly your visual attention and ability to form memories — deteriorates. (More colloquially, this is that “brain fog” we all experience after a late night.)

Your ability to learn new information is impaired, both by sleep deprivation before you learn new information and afterward.

You’re less likely to correctly read facial expressions, even interpreting some expressions — even neutral ones — as threatening.

You’re likely to be more cranky and react worse when presented with obstacles.

Beyond your severely impaired mental abilities, your body is affected, too: A lack of adequate sleep can contribute to weight gain, puts you at a higher risk of diabetes and heart disease, and makes you far less resistant to the common cold.
