Rising temperatures are having a devastating impact on sleep health worldwide, with the prevalence of sleep apnea expected to triple as nights get hotter. Researchers warn that this increase in sleep apnea events will disproportionately affect vulnerable populations and exacerbate existing health disparities.
In Australia's South Australian city of Adelaide, local researchers found that sweltering nighttime temperatures, such as 34.1 degrees Celsius, are linked to a greater risk of hospitalization for cardiovascular and mental health conditions. To investigate the impact of warming world on human sleeping patterns, the scientists conducted a study using under-mattress sleep sensors.
Their findings revealed that higher nighttime temperatures not only reduce the number of hours slept but also disrupt regular sleep patterns. Moreover, every 10 degrees Celsius increase in daily temperature resulted in an 8.4 percent increase in sleep apnea events in Chinese data collected from 51,842 people across 313 cities over three years.
Experts suggest several reasons for this correlation: high temperatures impair the body's ability to cool down at night, leading to lighter and more fragmented sleep; heat can influence behavior, making people more likely to drink alcohol, consume a poor diet, and engage in less physical activity, all of which are known risk factors for sleep apnea.
Physiologically, heat may also destabilize breathing control, increase fluid retention, and promote dehydration, further increasing the likelihood of sleep apnea. The researchers warn that those living in cities, particularly those exposed to high levels of air pollution, are already more likely to experience sleep apnea due to its chronic impact on nighttime breathing.
To mitigate these risks, experts recommend using indoor air filtering devices if online air quality databases show poor ratings and losing weight may be beneficial in reducing the risk of sleep apnea events. However, this is not without risks; men and individuals with preexisting mental health or sleep disorders are particularly vulnerable to sleep apnea in hot weather.
The Flinders University team aims to develop personalized advice and heat-warning systems for those at greater risk of experiencing sleep apnea events during heatwaves. Ultimately, their goal is to provide practical, evidence-based recommendations that can be applied during heat waves, particularly for vulnerable groups and people at higher risk.

I mean, umm... 
Rising temps are super bad for sleep health, right? 
Like, we already know that too much heat can mess with our breathing and stuff, so it's no surprise that it's linked to sleep apnea events tripling. But, wait, isn't climate change also supposed to make everything more equal and less health-disparity-y? 
I mean, shouldn't we expect people in hot cities to have better air quality and be healthier overall? 
It just seems like we're only talking about the most vulnerable folks being affected... or are we? 
! Rising temps are seriously affecting our sleep patterns and it's not just a matter of getting a good night's rest anymore. It's like, our bodies can't even cope with the heat and it's taking a toll on our mental health too 
. I mean, who needs to worry about sleep apnea when you're already stressed about climate change? 
. It's so unfair that we have to deal with this heat-induced chaos in our personal lives while the world just keeps on burning 
. And what really gets me is that vulnerable populations are going to be disproportionately affected 
. I mean, we already know that people living in cities with bad air quality are more likely to get sleep apnea, but now it's like our own homes are against us too 
they're working on a solution tho like heat-warning systems & personalized advice which is super cool 
losing weight might help reduce the risk too but its not just about dieting its about being mindful of ur health overall u gotta take care of urself when ur body's gonna be extra sensitive during heatwaves 
I mean, think about it, we're already living in a world where climate change is real, and now we're finding out that rising temps are messing with our sleep patterns? It's like, what's next? Will we be waking up every morning feeling like zombies? 
I know some people might say we should just take steps to reduce our carbon footprint, but come on, it's not that easy. We gotta find ways to adapt and deal with this new reality. And honestly, I think the researchers are onto something with their heat-warning systems - it's about time someone took a proactive approach to helping us stay safe in these extreme temperatures. But at the same time, we can't just blame the environment for our own health issues 
I'm getting worried about the impact of rising temps on our sleep health 
. The fact that it's gonna triple the risk of sleep apnea events is crazy 
. I'm all for taking measures to stay safe and healthy during heatwaves, but we gotta be smart about it too 
. Losing weight might seem like an obvious solution, but it's not just about willpower 
. I'm excited to see the personalized advice and heat-warning systems that Flinders University is working on 
.
and maybe try losing some weight? but honestly, its scary how this is gonna affect our health esp when theres all this air pollution in cities already
