Sleeping an extra hour each night can help you lose weight, study finds world news
Getting an extra hour of sleep every night can help people cut about 270 calories from their daily diet — the equivalent of three chocolate chip cookies, a new study has found.
Over three years, that could result in a 26-pound weight loss simply from getting more sleep, the researchers said.
A team from the University of Chicago wanted to study how sleep interacts with obesity.
They wrote in the journal Jama Internal Medicine that young, overweight adults who typically slept less than 6.5 hours a night were able to add another 1.2 hours a night after undergoing counseling to improve their sleeping habits.
dr Esra Tasali said, “If healthy sleep habits are maintained over a period of time, it would result in clinically meaningful weight loss over time.”
She said the study deliberately made no attempt to restrict diets or lifestyles to replicate everyday life.
“In our study, we only manipulated sleep, they could eat whatever they wanted,” she added.
dr Tasali also found that reducing the use of devices like cell phones and laptops before bed helped people sleep better and longer.
She said that after just one sleep counseling session, the participants’ sleeping habits changed to ensure they slept longer.
She added, “We simply coached each individual on good sleep hygiene and discussed their own personal sleep environment and provided tailored advice on changes they could make to improve their sleep duration.”
The adults in the study were 21 to 40 years old and had a body mass index (BMI) between 25 and 29.9 at the start of the study, meaning they were overweight.
