News Release 7-Feb-2022

In a randomized clinical trial with 80 adults, published February 7 in JAMA Internal Medicine, Tasali and her colleagues at UChicago and the University of Wisconsin–Madison found that young, overweight adults who habitually slept fewer than 6.5 hours a night were able to increase their sleep duration by an average of 1.2 hours per night after a personalized sleep hygiene counseling session. The sleep intervention was intended to extend time in bed duration to 8.5 hours — and the increased sleep duration compared to controls also reduced participants’ overall caloric intake by an average of 270 kcal (calories) per day.
“Over the years, we and others have shown that sleep restriction has an effect on appetite regulation that leads to increased food intake, and thus puts you at risk for weight gain over time,” said Tasali. “More recently, the question that everyone was asking was, ‘Well, if this is what happens with sleep loss, can we extend sleep and reverse some of these adverse outcomes?”
