* **Weekend sleep:** A recent study has found that enjoying extra sleep on weekend mornings may lower the risk of heart disease by 20%. * **Sleep quality:** The study focused on the quality of sleep, not just the quantity. * **Heart disease risk:** The study found a strong correlation between weekend sleep and a lower risk of heart disease. * **Mechanism:** The study suggests that the mechanism behind this correlation is the body’s natural circadian rhythm. * **Benefits:** The benefits of extra sleep on weekends extend beyond just heart health.

The study, published in the Journal of the American Medical Association (JAMA), investigated the relationship between sleep duration and heart disease risk. Researchers analyzed data from over 10,000 adults, tracking their sleep patterns and heart disease events over a period of 10 years. The study found that those who slept longer on weekends, even if they slept less during the week, had a lower risk of developing heart disease. This finding suggests that weekend sleep can act as a buffer against the negative effects of weekday sleep deprivation.
