There’s very little information about the negative influence of poor sleep in older adults and women transitioning across menopause,” said Center Directors, Marie-Pierre St.-Onge, Ph.D., and Lori Mosca, MD. PhD, MPH

“We had done studies that showed that restricting sleep — very severely restricting sleep — increased food intake and could lead to obesity, which increases the risk of hypertension and cardiovascular disease,” St.-Onge said. “We thought, perhaps, there’s specifically in women, a link between poor, short sleep duration and cardiovascular disease.” 

“What we did was restrict sleep but to a smaller extent than we had done in the past — but for a longer period of time, which reflects more closely what short sleepers actually do in the general population,” St-Onge said.

"Blood results and other data are still being analyzed, but findings so far can already teach lessons for the general population and health care professionals," St.-Onge said.

Not only were blood pressure readings better when women received adequate sleep; stable schedules, including regular bedtime and rising times, also seemed to improve circadian rhythms and other markers.

“It’s important for the population and health practitioners to know that sleep quality is something that should be asked about in health encounters. Just as you would ask about diet, just as you would take blood pressure and weight, just as you would ask about a person’s mood, you should be asking about their sleep,” St.-Onge said.
