A 2019 study demonstrated that sleeping in on the weekend did not make up for the metabolic damage that was done by sleep deprivation during the workweek. The damage was measured in terms of heart disease, diabetes, obesity, and other metabolic criterion.
One limitation of the ESC study was that more than 75 percent of participants did not report getting fewer than seven hours of sleep throughout the week, which reduced the relevance of the results. Additionally, the study relied on self-reported data on sleep habits, so it may not be entirely accurate.
Furthermore, the participants could have received other forms of treatment or taken other measures over the 14 years to boost or neglect their heart health. These factors were not reported.
Currently, the American Academy of Sleep Medicine has maintained its recommendation of getting at least seven hours of sleep per night.
