Science Daily reported recently that a new study by researchers from St. Luke’s-Roosevelt Hospital in New York City and Columbia University seems to have found a link between how well we sleep and how badly we eat. In the study, people who were didn’t get enough sleep tended to feel hungry more often, eat more, and gain more weight. While this doesn’t mean we can somehow “sleep away the pounds,” it does suggest that sleeping well makes it noticeably easier to eat well–and we already know that eating well, in turn, helps us sleep better.
In other words, paying special attention to getting enough sleep, which for most of us means making a decision to go to sleep earlier at night, can help us eat better and feel more healthy, which in turn can help us sleep even better: a snowball effect, though I can’t tell you whether the effect would be small or large.
