New research presented at the European Society of Cardiology's annual congress indicates that compensatory sleep during the weekends could potentially reduce the risk of developing heart disease by 19%. The study, which analyzed data from participants over a span of nearly 14 years, found that those who made up for lost sleep on weekends were less likely to experience cardiovascular conditions such as heart disease, heart failure, atrial fibrillation, and stroke.

The researchers, led by Yanjun Song from the National Center for Cardiovascular Disease in Beijing, measured sleep patterns using activity-monitoring watches. Participants were divided into four groups based on their weekend sleep compensation. Group No. 1 slept 0.26 to 16.05 fewer hours on the weekends, while group No. 4 slept 1.28 to approximately 16 more hours on weekends compared to weekdays.

Among the participants who regularly experienced insufficient sleep on weekdays, those in the group with the highest level of weekend compensatory sleep had a 20% lower risk of heart disease compared to those who made up for sleep the least. The study found no significant differences in the findings based on gender.

While the study focused exclusively on the UK population, its findings highlight the detrimental effects of chronic sleep deprivation on cardiovascular health. Dr. Nieca Goldberg, a medical director at Atria New York City and clinical associate professor at New York University's Grossman School of Medicine, noted that the study has limitations but underscores the importance of consistent sleep patterns for optimal heart health.

Previous research on weekend sleep catch-up has yielded mixed results. Dr. Nour Makarem, an assistant professor of epidemiology at Columbia University, explained that differences in sleep duration and timing between weekdays and weekends, known as social jet lag, have been linked to an increased risk of heart disease. Conversely, another study suggested that attempting to compensate for sleep deprivation may worsen diet, lead to weight gain, and reduce insulin sensitivity.

Although more regular sleep patterns each day of the week are recommended for overall heart health, the latest research suggests that sufficient compensatory sleep during the weekend may provide some protection against heart disease when a consistent sleep schedule is not possible. The study also accounted for genetic risk factors, which strengthens the association between weekend sleep catch-up and lower heart disease risk.

The reasons behind this correlation may be attributed to the influence of sleep on blood glucose and blood pressure levels, dietary choices, and the risk of obesity. Lack of sleep has been linked to elevated risks of high blood pressure, high cholesterol, heart attack, obesity, diabetes, and stroke. Additionally, interrupted sleep patterns could heighten the risk of arrhythmias and high blood pressure.

Dr. Martha Gulati from Cedars-Sinai Medical Center in Los Angeles emphasized that there are still unanswered questions, such as the threshold of excessive weekend sleep and whether there is a minimum amount of daily sleep that cannot be effectively compensated for. Future research could explore if individuals who consistently obtain sufficient sleep have an even lower risk of heart disease.

To promote heart health, it is recommended to aim for at least seven hours of sleep every night and maintain a consistent sleep schedule. Regular sleep patterns, including consistent sleeping and waking times, are important for overall well-being. Individuals struggling with sleep issues are encouraged to discuss them with their healthcare providers, as proper sleep is a crucial component of heart health preservation.
