Summary: Research presented at ESC Congress 2024 shows that catching up on sleep during weekends can reduce the risk of heart disease, especially for those who experience sleep deprivation during the week. The study analyzed nearly 91,000 participants from the UK Biobank project, grouping them into quartiles based on the amount of compensatory sleep they received on weekends. Participants in the quartile with the most compensatory sleep were found to be 19% less likely to develop heart disease compared to those with the least compensatory sleep.
Three Key Takeaways:
- 19% Lower Heart Disease Risk: Participants who got the most compensatory sleep on weekends were 19% less likely to develop heart disease than those who received the least amount of catch-up sleep.
- Compensatory Sleep Matters: The study highlights the importance of compensatory sleep on weekends, particularly for those experiencing weekday sleep deprivation, as a way to lower the risk of heart disease.
- Extensive Data Analysis: The findings are based on a long-term study involving nearly 91,000 participants, offering evidence that weekend catch-up sleep plays a crucial role in cardiovascular health.
The demands of the working week, often influenced by school or work schedules, can lead to sleep disruption and deprivation. However, new research presented at ESC Congress 2024 shows that people who “catch up” on their sleep by sleeping in at weekends may see their risk of heart disease fall by one-fifth.
“Sufficient compensatory sleep is linked to a lower risk of heart disease,” says study co-author Yanjun Song, PhD, of the State Key Laboratory of Infectious Disease, Fuwai Hospital, National Centre for Cardiovascular Disease, Beijing, China, in a release. “The association becomes even more pronounced among individuals who regularly experience inadequate sleep on weekdays.”
It is well known that people who are sleep deprived “sleep in” on days off to mitigate the effects of sleep deprivation. However, there is a lack of research on whether this compensatory sleep helps heart health.
Evaluating Link Between Compensated Weekend Sleep and Heart Disease
The authors used data from 90,903 subjects involved in the UK Biobank project, and to evaluate the relationship between compensated weekend sleep and heart disease, sleep data was recorded using accelerometers and grouped by quartiles (divided into four approximately equal groups from most compensated sleep to least). Quartile 1 (n = 22,475) was the least compensated, having -16.05 hours to -0.26 hours (ie, having even less sleep); quartile 2 (n = 22,901) had -0.26 to +0.45 hours; quartile 3 (n=22,692) had +0.45 to +1.28 hours, and quartile 4 (n=22,695) had the most compensatory sleep (1.28 to 16.06 hours).

Sleep deprivation was self-reported, with those self-reporting less than seven hours of sleep per night defined as having sleep deprivation. A total of 19,816 (21.8%) of participants were defined as sleep deprived. The rest of the cohort may have experienced occasional inadequate sleep, but on average, their daily hours of sleep did not meet the criteria for sleep deprivation. The authors recognize this as a limitation to their data.
Hospitalization records and cause of death registry information were used to diagnose various cardiac diseases including ischaemic heart disease, heart failure, atrial fibrillation, and stroke.
Study Findings
With a median follow-up of almost 14 years, participants in the group with the most compensatory sleep (quartile 4) were 19% less likely to develop heart disease than those with the least (quartile 1). In the subgroup of patients with daily sleep deprivation those with the most compensatory sleep had a 20% lower risk of developing heart disease than those with the least. The analysis did not show any differences between men and women.
“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 than those with the least,” says co-author Zechen Liu, also of State Key Laboratory of Infectious Disease, Fuwai Hospital, National Centre for Cardiovascular Disease, Beijing, China, in a release.
