I used to be proud that I only slept four hours a day. Until I realized that I was experiencing sleep deprivation.

Studies have shown that people function best after seven to eight hours of sleep, so I now aim for a solid seven hours, the amount associated with the lowest mortality rate.

According to an article published in the New York Times, “Sleep is the New Status Symbol,” the US Centers for Disease Control and Prevention call sleeplessness a public health concern. Good sleep helps brain plasticity, studies in mice have shown; poor sleep will make you fat and sad, and then will kill you. It is also expensive: last year, the RAND Corporation published a study that calculated the business loss of poor sleep in the United States at $411 billion — a gross domestic product loss of 2.28 percent.”

According to Dr. Matthew Walker, of U.C. Berkeley, “Sleep is the single most effective thing you can do to reset your brain and body.”

So when someone you know is busy tweeting at 3AM every morning, and claims he only sleeps three hours a day, he is probably sleep deprived. Just calling it like I see it...

Wishing everyone a relaxing and restful Memorial Day.
