WAll have a reason to take climate change personally. High temperatures not only lead to huge events such as drought, thermal waves, forest fires and floods, but also they It affects human health– AllergiesCardiovascular diseases, the spread of pathogens transmitted by water, and more. Now, the world of warming appears to affect us in another way, which may threaten life. This is according to a new review that has not been reviewed before paper May 18 at the 2025 gathering of The American Chest Association In San Francisco. The researchers found that with increased temperature, as well as cases of injury and severity Sleeping breathing (OSA), Risk From high blood pressure, heart attack, stroke and death.
“We were surprised by the size of the relationship between the surrounding temperature and the intensity of OSA,” said Bastian Leshat, the main author of the paper and a research fellow in southern Australia. Institute of Health and Medicine Research FlindersIn a statement accompanied by the last offer. “This study really highlights the societal burden associated with the increase in the spread of OSA due to high temperatures.”
In order to conduct their business, the LeChat and his team collected data from 125295 users of a breathing stop during the enclosure, in 41 countries, collecting readings registered from January 2020 to September 2023. The sensor consists of an executable mat under the ranking point that is at the chest level with sleep. Changes in air pressure inside the physical, respiratory system and even heart movement. “By analyzing these signals with the royal machine learning … the device can estimate a set of scales, including sleep duration, sleep stages, waking up, and breathing periods,” said Leshat in an e -mail to time. Breathing scandalies It is what constitutes respiratory failure.
The researchers collected an average of 509 nights of readings from each individual, then tied the results to the surrounding temperature models 24 hours. The results were remarkable, which indicates a great connection between breathing and temperature in 29 countries that were studied, or more than half. In those places, the temperature rise was associated with an increase of 45 % in the possibility of an individual with at least one loop of breathing stopping on a specific night. This does not come cheap. Researchers are estimated in their numbers, that the increase in breathing stops during their occurrence. Years of healthy life– or years without disability or death – in 2023 alone. The loss of years of healthy life has an economic cost as well, as it is estimated at 32 billion dollars in the productivity of the workplace in 2023.
The relationship between high temperatures and OSA is not new. The climate changes brings with it more extreme heat, including during our sleep. Predominantly Do not decrease as they did before. The researchers estimate that the health and economic strikes caused by the heat -related self -cutness have increased by 50 % to 100 % since 2000. Over 1.5°C From warming in 2024.
“Our economic estimates in the paper indicate that the increase in the spread of OSA is driven by higher surround temperatures that can lead to a multi -dollars global societal cost, as well as the most poorest human health and well -being,” says Lekhhat.
At the present time, the mechanism that connects the temperature and the stop breathing is not clear. Lakhtat and his colleagues speculate that heat may lead to lighter sleep – the sleeping stage during which breathing stops to be more severe. Behavioral factors may also be: When temperatures are higher, individuals may be less likely to wear continuous positive air pressure masks (CPAP), which is described to reduce or prevent self -cut.
Whatever the reason, we may all feel influenced. “Sleep is the third pillar of health, along with nutrition and exercise,” says Leshat.[It] It is necessary for both physical and mental well -being. “
