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 results showed that participants who got the most weekend sleep had a 19% lower incidence of heart disease compared to those with the least weekend recovery sleep. However, experts caution that the study establishes a correlation, not causation, and other unaccounted factors may have influenced the results.

Experts also warn that weekend sleep cannot fully compensate for the health risks linked to chronic sleep debt, including an elevated risk of obesity. “Extra weekend sleep may reduce tiredness but is unlikely to address risks like obesity caused by chronic sleep deprivation,” Dr. Rishi explained.
