Weekend sleep in linked to lower heart ******** risk

People who “catch up” on lost sleep at weekends may potentially lower their risk of heart ******** by up to 20 per cent, new research suggests.

Data from more than 90,000 people in the *** suggests compensating for lack of sleep during the week with extra snooze time at the weekend can mitigate the negative effects of sleep deprivation.

Findings presented at the ********* Society of Cardiology Congress in London showed sleep-deprived people with the most “catch-up” sleep at weekends saw their risk of heart ******** fall by a fifth, compared to those who had no extra shut-eye or slept even less at weekends.

Study author Yanjun Song, of the National Centre for Cardiovascular ********, Fuwai Hospital, in Beijing, China, said: “Sufficient compensatory sleep is linked to a lower risk of heart ********.

“The association becomes even more pronounced among individuals who regularly experience inadequate sleep on weekdays.”

For the study, the authors looked at self-reported data from 90,903 people who are part of the *** Biobank project, which holds medical and lifestyle records of half a million individuals.

Of them, 19,816 met the criteria for being sleep deprived.

Hospital records and cause of ****** registry information were used to identify those who had heart *********, heart ********, irregular heart rhythm and *******.

Over a follow-up ******* of 14 years, the team found people with the most extra sleep (ranging from 1.28 to 16.06 hours of additional sleep during weekends), were 19 per cent less likely to develop heart ******** than those with the least amount of compensatory sleep (ranging from losing 16.05 hours to losing 0.26 hours over the weekend).

In a sub-group of people with daily sleep deprivation, those with the most compensatory sleep had a 20 per cent lower risk of developing heart ******** than those with the least, the researchers said.

Study co-author Zechen Liu, also of the National Centre for Cardiovascular ********, said: “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 ******** than those with the least.”

Professor James Leiper, associate medical director at the British Heart Foundation, who was not involved, said: “Lots of us don’t get enough sleep due to work or family commitments, and while a weekend lie-in is no replacement for a regular good night’s rest, this large study suggests that it might help reduce risk of heart ********.

“We know that lack of sleep can affect our overall wellbeing, and this research is an important reminder of how important it is to try to get at least seven hours sleep every night.”
