An analysis of data from 90,000 participants found a link between extra sleep on the weekends and a lower risk of heart disease.

People who compensate for sleep lost during the workweek had their risk fall by up to 20%.

Of the data set, about 1/5 of participants were sleep-deprived, meaning they slept less than seven hours per night.

“Our results show that for the significant proportion of the population in modern society that suffers from sleep deprivation, those who have the most ‘catch-up’ sleep at weekends have significantly lower rates of heart disease,” study co-author Zechen Liu said.

However, researchers warn that this is not a substitute for healthy sleep patterns.
