Researchers analyzed data from the National Health Interview Survey to understand how many adults in the United States report never feeling rested. They looked at responses from adults aged 18 to 64 during 2017 and 2018. The survey asked people to think about the past week and report if they never felt rested upon waking.
The main finding was that women were more likely than men to say they never felt rested. The study did not report specific numbers or percentages for this difference. It also did not look into why this difference might exist or what specific factors could be involved.
This was an observational survey, which means it simply recorded what people reported at one point in time. It cannot prove that being a woman causes someone to feel less rested. The feeling of being rested is self-reported and subjective, and the data only reflects one specific time period.
Readers should view this as a snapshot of how some adults reported feeling during those years. It highlights a difference worth further investigation but does not explain the reasons behind it. More research would be needed to understand the causes and whether this pattern still holds true today.
