Could Donald Trump's Strange Behavior Be Caused By Sleep Deprivation?

Is Donald Trump suffering from a serious case of sleep deprivation?

Timothy Eagan wrote: "Trump gets by on barely half the amount of sleep recommended for a healthy life....three or four hours, and sometimes just 90 minutes."

The Times say sleep deprivation makes people "cranky and temperamental," "impulsive," and "smaller things set them off."

The newspaper suggests that may account for his outbursts on the campaign trail where the GOP front runner said he wanted to punch a protester and told a venue to keep the lights off as he was speaking.

Sleep deprivation expert Dr. Steven Feinsilver says lack of sleep may also explain some of Trump's fits and disposition.

"Sleep deprivation has effects on both physical well being and mental well being and actually emotional well being," he told IE. "We are all designed to get at least seven-and-a-quarter hours of sleep. If you get less than that, it is associated with making a lot of errors."
