As daylight saving time looms, researcher sheds light on health effects of not getting enough rest, reports The Harvard Gazette.

Jeanne Duffy is an associate professor of medicine at Harvard Medical School and a sleep researcher at Brigham and Women’s Hospital. She took a break from a study exploring how sleep and metabolism interact — inadequate sleep has been tied to obesity and diabetes — to shed light on the growing body of research linking our sleep habits and our health, and to offer suggestions on the best way to bounce back from losing an hour when we “spring ahead.”
