Adherence
Vigorous or moderate exercise significantly reduces the risk of sleep disturbance in individuals with severe sedentary behavior, although this benefit is not mediated by the measured blood-cell-based inflammatory biomarkers.
If you sit for more than 8 hours a day, doing 150 minutes of moderate or 75 minutes of vigorous exercise per week significantly lowers your risk of sleep problems. However, this benefit is specific to those with high sitting times; for those who are already active, the added benefit on sleep risk was not statistically significant in this study.
In the population with severe sedentary behavior, higher exercise intensity was significantly associated with a lower risk of sleep disturbance symptoms (OR = 0.687, 95% CI: 0.551-0.857, P = 0.002)
Why this rating
Large sample size and robust adjustment, but cross-sectional design limits causal inference regarding the specific mechanism of exercise.
