DURHAM, N.C. — Sufficient sleep has been proven to help keep the body healthy and the mind sharp. But it’s not just an issue of logging at least seven hours of Z’s.
A new study on sleep patterns suggests that a regular bedtime and wake time are just as important for heart and metabolic health among older adults.
In a study of 1,978 older adults publishing Sept. 21 in the journal Scientific Reports, researchers at Duke Health and the Duke Clinical Research Institute found people with irregular sleep patterns weighed more, had higher blood sugar, higher blood pressure, and a higher projected risk of having a heart attack or stroke within 10 years than those who slept and woke at the same times every day.
Irregular sleepers were also more likely to report depression and stress than regular sleepers, both of which are tied to heart health.
