Arianna: 'Orgasms Are Mother Nature's Ambien'

Sleep isn't just important for your physical health-- it's also the key to a good sex life. 

Appearing on "The Late Show with Stephen Colbert,"  Huffington Post editor-in-chief Arianna Huffington said that there's a "connection between sleep deprivation and erectile disfunction."

"Orgasms are Mother Nature's Ambien-- without side effects!" she said. 

Science supports this theory. As Men's Health magazine explains, "testosterone levels plummet when you don't get enough sleep, making it much tougher to get and sustain an erection. But you may be too tired to care, since low T also triggers a drop in men's desire for sex."

Watch Huffington's interview in the video above and read more about the connection between sleep and sex in her new book, The Sleep Revolution.
