Association of Domain-Specific Physical Activity with Sleep Disorders in U.S. Adults: A Cross-Sectional Study Based on NHANES.

Key takeaways

This study looked at 25,732 American adults, average age about 50, in a national health survey. It compared sleep problems against activity at work, activity while getting around, and activity in free time. Because everyone was measured at one moment in time, it can only show a link, not prove that exercise changes sleep. There is no kidney angle here.
