Among men, sleeping ≥8 hours is associated with a significantly lower risk of high LDL cholesterol compared to sleeping 6-7 hours, suggesting a potential benefit of long sleep for this specific lipid marker in men.
For men, sleeping 8 hours or more may be associated with lower LDL cholesterol levels compared to sleeping 6-7 hours. However, this does not mean long sleep is universally better, as other lipid markers (triglycerides, HDL) did not show significant associations in men. Men should prioritize overall sleep quality and consistency.

On the other hand, it was observed that the risk of a high LDL cholesterol level was lower among men sleeping ≥8 h... Specifically, the OR with regard to a high LDL cholesterol level among those who slept ≥8 h was significantly lower than for those who slept for 6 to 7 h.
Why this rating
Cross-sectional design limits causality, but the finding is statistically significant and adjusted for covariates.
