According to a new study recently presented by researchers at the State Laboratory of Infectious Diseases in China, getting more sleep on weekends may be beneficial as it can reduce the risk of heart disease by almost 20%.
The researchers, using self-reported data on more than 90000 people, created four cohorts depending on how long the participants slept. Follow-up of participants lasted for about 14 years, and by analyzing hospital records and death registries, the study authors found that those who “offset” their ideal bed time (7 to 9 hours each night) with more sleep on weekends were specifically 19% less likely to develop heart disease than other people.
Replenishing lost sleep time at the weekend

“This study demonstrates our body’s remarkable ability to recover energy, even after previous periods of sleep deprivation. While the link between sleeping well and heart health is well documented, the benefit seen in this study from such a habit is remarkable,” the scientists state.
“While of course compensatory sleep, i.e. catching up on weekends, as the new study suggests may be useful in the short term, it is not an effective approach for optimal mental and physical health,” they pointed out. As they explained:
“Constant deprivation can lead to a build-up of stress hormones, imbalances in our metabolism and an increase in inflammation, problems that a few extra hours of sleep cannot easily correct. Over time, this can contribute to serious health issues such as obesity, diabetes and heart disease, as this study also demonstrates. It is therefore vital to maintain a regular sleep schedule and prioritise both quality and quantity on a daily basis.”
Can naps help to “make up” for lost hours?
Naps can be a valuable tool for boosting energy, but they are not a sustainable way to make up for lost sleep, researchers point out.
The body’s restorative processes, such as tissue repair, memory consolidation and hormonal regulation, occur during uninterrupted, consistent nighttime sleep. So while a midday nap can help, the pursuit of a quality and adequate night’s sleep should always be our primary concern, they conclude.
