Sleep apnea may be quietly changing your body in an unexpected way, study finds

Researchers in Israel found that people with obstructive sleep apnea tend to have a higher muscle mass index and lower muscle density, which may indicate less functional muscle. The study analyzed data from 209 adults and found a significant link between OSA and higher muscle mass index. The findings suggest that OSA may be a marker of underlying metabolic dysfunction affecting multiple systems, including muscle health.
