The research team examined sleep records from 90,903 participants who self-reported their sleep duration. Of these, 19,816 individuals averaging less than seven hours of sleep per night were classified as sleep-deprived. These participants were then divided into four groups based on the amount of sleep they got on weekends and tracked over an average of 14 years.
The findings revealed that the group with the most weekend sleep had a 19% lower rate of heart disease compared to the group with the least weekend sleep. However, experts caution that the study establishes a correlation, not causation, and other unaccounted factors may have influenced the results.

The study underscores the importance of consistent sleep patterns for overall health, while highlighting that compensatory weekend sleep may offer some cardiovascular benefits for those struggling to get enough rest during the week.
