Climate change could have almost unimaginable consequences. Since the distribution mosquito-borne diseases before increase turbulenceexperiencing more obvious effects such as sea ​​level rise or extreme weather events. It can also affect people’s health on many levels, increasing allergies, increasing deaths from heatwaves, and even disrupting their sleep. The latter has just been shown in a study recently published in Cellled by a team of scientists from University of Copenhagen.

In fact, what matters is quite obvious. We all live through every summer consequences of sleeping in the heat. However, climate change could exacerbate this problem. And the most serious thing is that, as always, the inhabitants of countries with low economic resources.

The reasons for the latter are not clear, although certain hypotheses. What is clear is that while there are those who calmly claim that climate change is not preventing them from sleeping at night, this is not the case. What happens is that they either don’t realize it or don’t want to do it.

The Importance of Leaving the Lab

The relationship between temperature rise or fall and sleep has been measured in many studies that preceded the one just published. However, this was done in laboratory conditions. This removes from the equation changes that participants make to their environment better sleep, despite the heat or cold. Heating, air conditioning, and plenty of blankets are some of the resources we typically use at home.

So to resolve this detail, the authors of this new study used anonymous sleep data extracted from the activity bracelets of 47,000 people from 68 countries on every continent except Antarctica. In total, about 7 million records were analyzed. It helps to analyze the dream of all these people in real conditions, in their own homes.

The data was obtained from sleep records of activity bracelets.

So they saw a big difference from previous studies. And it is that although these previous investigations have shown that Cold and heat affects sleep in the same way, this new study found more adverse effects of rising temperatures. Maybe because it’s easier adapt the environment to the cold.

They found that the effects were more dramatic in older people, women and residents of countries with limited economic resources. The latter may be due to the fact that these people have more difficult access to air conditioning. However, there is no way to know for sure, since the activity bracelets do not indicate whether these people have these devices at home. Now what does all this have to do with changing of the climate?

This is how climate change keeps you awake at night

Greenhouse gas emissions are gradually leading to a global increase in temperature, which is also accompanied by an increasing heat waves.

In this study, the authors found that on very warm nights with over 30ºCdecreased average sleep just over 14 minutes. People tend to go to bed later and wake up earlier. Not to mention nocturnal awakenings. In total, it was very difficult to oversleep the recommended seven hours.

And the worst thing is that if global temperatures continue the current evolution due to climate change, by 2099, the heatwave could cut 50 to 58 hours of sleep a year. person. It may not seem like much, but sleep is vital for us to stay physically and mentally healthy. So while all of this may seem like a minor concern, with all the effects of climate change, this is yet another reason to try to stop it. Because yes, climate change keeps even those who deny it awake.
