“We’re starting to learn in more recent years that this chronic sleep loss affects things like diabetes, a tendency for obesity to occur…”

“If you always are in a state of sleep debt, just cutting your sleep by as little as an hour per night, you are going to be a little bit more hungry, and eat a little bit more. This is a major problem, in this country particularly since we have an epidemic of obesity.”

“Sleep deprivation is unique to the human. There is no animal that tries to sleep deprive itself. They just sleep what they need to sleep. We are totally unique in the desire to overcome our sleepiness and stay awake no matter what, even if our body is screaming to go to bed.”

If the science behind sleep debt intrigues you, I recommend the book Sleep Thieves.
