Climate change increases severity of obstructive sleep apnea: Study

A new large study on Sunday claimed that rising temperatures increase the severity of obstructive sleep apnea (OSA).

Published at the ‘ATS 2025 International Conference,’ the study also found that, under the most likely climate change scenarios, the societal burden of OSA is expected to double in most countries over the next 75 years.

In addition to highlighting the critical importance of limiting global warming, the findings also emphasise the immediate need for strategies to alleviate the health and economic impacts of OSA as it becomes more common and severe, researchers said.

"This study really highlights the societal burden associated with the increase in OSA prevalence due to rising temperatures," said Bastien Lechat, a senior research fellow at FHMRI: Sleep Health at Flinders University.
