Although high ambient temperatures have been linked to negative health outcomes including reduced sleep duration and quality, the association between increased average ambient temperatures and the severity of OSA remains unclear, wrote Bastien Lechat, PhD, a research fellow in sleep health at Flinders University, Adelaide, Australia, and colleagues, in their abstract.

Previous cross-sectional studies have shown an association between temperature and OSA severity, which prompted the idea for the current study, Lechat said in an interview. “We have access to a consumer
