Rising temperatures are wreaking havoc on our sleep patterns, and the consequences could be catastrophic. A study conducted by researchers at Flinders University in Australia has found that as nights get hotter around the globe due to climate change, the prevalence of sleep apnea is expected to increase by as much as threefold.
When nighttime temperatures soar, it can disrupt our natural sleep-wake cycle, making it harder to fall asleep and stay asleep. The research, which involved giving under-mattress sleep sensors to over 67,000 people across 17 European countries, found that the prevalence of sleep apnea events increased by 13 percent at the peak of a heatwave.
But why is this happening? According to researchers, high temperatures impair our body's ability to cool down at night, leading to lighter and more fragmented sleep. Additionally, heat itself can destabilize breathing control, increase fluid retention, and promote dehydration, all of which can make the upper airway more collapsible and increase the likelihood of sleep apnea.
The impact of climate change on sleep health is not limited to Australia, however. Chinese scientists have also found a correlation between rising temperatures and an increased risk of sleep apnea. In fact, every 10 degrees Celsius increase in daily temperature resulted in a 8.4 percent increase in sleep apnea events.
But what's concerning is that this increase in sleep burden will disproportionately worsen existing health disparities. For those with lower socioeconomic status, the effects of heat on sleep duration may be 10 to 70 percent greater. Furthermore, exposure to air pollution, particularly nitrogen dioxide, can exacerbate symptoms for people with existing sleep apnea.
So what can we do to mitigate this risk? Researchers suggest using indoor air filtering devices if online air quality databases show that your city ranks poorly, and losing weight could also be a way of reducing the risk of sleep apnea. Additionally, simple solutions such as ensuring good hydration before bed or using cooling mattress toppers may help prevent apnea events during heatwaves.
Ultimately, the goal is to develop practical, evidence-based recommendations that can be applied during heatwaves, particularly for vulnerable groups and people at higher risk. As temperatures continue to rise, it's clear that we need to take action to protect our sleep health – not just our lives.

I'm getting really worried about the impact of climate change on our bodies, especially when it comes to something as important as sleep. I mean, 3x more people with sleep apnea? That's a huge concern for me. I've noticed that when it gets hot outside, I have trouble falling asleep and I wake up feeling so tired all the time. It makes sense that our bodies just can't cool down properly at night when it's scorching outside.
. Like, have you ever tried sleeping in a heatwave? It's literally impossible 
. And now scientists are saying that it could lead to like 3 times more cases of sleep apnea? That's crazy! 
I mean, I knew high temps were bad for us, but I didn't realize they were so bad for our brains too 
. And what's even worse is that this is gonna hit the most vulnerable people the hardest 
. We need to find ways to deal with it ASAP 
, like using air filters or losing weight, whatever works 
. It's just not right that we have to fight climate change and now sleep apnea too 
. we need to do more than just offer simple solutions, we need concrete steps to address this issue. like, how can we make indoor air quality better in all cities, not just the ones that have poor air quality databases 
. and what about long-term solutions? can we actually reduce our carbon footprint and mitigate climate change without causing more sleep problems for some people? I wish there was a clear answer to these questions 
.
, they're also making us more likely to get sleep apnea 
. It's not rocket science, but I guess we humans tend to underestimate ourselves sometimes 
. The more I think about it, the more obvious it is that we're gonna have to get creative with some simple solutions if we wanna mitigate this risk 
.
Rising temps are literally killing us and now scientists are telling us to lose weight and use air filters... easy for them to say, right? 
The fact that it's gonna affect people with lower socioeconomic status the most is just another kick in the teeth. We need real solutions not just a bunch of Band-Aid fixes. How about governments take action instead of just being all "oh no climate change"... what are they even doing? 
! I mean, can you imagine waking up every morning feeling like you've been hit by a truck? Not fun! 
. Let's get creative and find ways to protect our sleep, for real
