It does not allow you to live in peace. Scientists have studied how humans adapt to extreme heat

A new study by scientists in China measures the extent to which outdoor activity decreases on days with high temperatures.

A new study by scientists has confirmed that extreme temperatures make people less likely to participate in outdoor activities. A data-rich study from China shows that people are 5 percent less likely to visit public parks when temperatures reach 30 degrees Celsius, and 13 percent less likely to visit when temperatures reach 35 degrees Celsius, according to MIT News.

“We observed adaptation,” says Xiqi Zheng, an MIT professor and co-author of a new paper detailing the study’s findings. “Environmental hazards harm the quality of everyday life. Yes, people protect themselves by limiting their activities, but they lose the benefits of going out in nature or meeting friends in the parks.”

The study adds to our knowledge of the impact of climate change by measuring the impact of high temperatures on people’s daily activities – not just over longer periods of time, but how they move from warmer to colder time zones.

“Given this adaptation during the day, we found that extreme temperatures actually have a much greater impact on human activity than previous daily or monthly estimates suggest,” says Yichun Fan, an MIT doctoral student and co-author of the paper.

To conduct the study, the researchers used anonymous data on 900 million cell phone users in China in 2017 and studied a total of 60 billion individual cell phone location queries per day. Using this data, the scientists also looked at activity in 10,499 parks around the country and compared overall usage rates under different conditions. And they got temperature data from about 2,000 weather stations in China.

Ultimately, the scientists wrote in the paper that they were “able to document major and significant depressive and activity-retarding effects” when they visited the park as a result of the extremely high temperatures.

“Humans have patterns of intraday adaptation that have not been documented in the previous literature. This has important implications for the effects of heat on humans and how future climate change will affect people’s activities and health,” says Phan.

As Zheng points out, the changing use of public spaces affects daily life not only in terms of individual activities and exercise, but also in terms of social and communal life.

“Extreme climates reduce people’s ability to socialize in cities or just watch kids playing basketball or soccer, which is not a good thing. We want people to have a diverse city life. This adaptation has a social cost.”

Studies show that people clearly adapt to temperature fluctuations. The data also shows that evening use of the parks increases on extremely hot days, but only after temperatures drop. While this may seem like a useful adaptation to very hot weather, scientists citing current research suggest that people may be sleeping less as a result of making this type of change in their daily routines.

“Adaptation has its own cost, too. People have significantly increased their nighttime outdoor activity, which means they sacrifice their sleep time, which will have significant health consequences,” Phan said.

Overall, the study provides data and a method to better characterize the impact of climate change on human activities in detail.

“The more and more detailed data we have on future climate scenarios, the better predictions that reflect dynamic human behavior and health outcomes,” says Fan, whose doctoral research includes this work and other related research on climate and urban activity.

The researchers also note that the methods used in studying this topic could be applied to future additional analyzes of many other aspects of urban life, including street-level retailing and similar things with implications for economic activity, real estate, and urban planning.

Previously Focus He wrote that the effects of extreme heat will affect 90% of the world’s population. According to scientists, the world population will face a potential increase in social inequality and the inability to reduce carbon dioxide emissions into the atmosphere.
