If the work is difficult all year, it becomes even more so in the summer: working with the heat that burns the body and mind is certainly not easy, and all the work can not guarantee a correct temperature. , ideal to get the best of it
Yes, because the heat does not only affect the body, but also the cognitive processes: even science says it, in a study that someone has already defined as revolutionary.
The study, conducted by a team of researchers from the Harvard TH Chan School of Public Health, pointed out how students who slept without air conditioning during a heat wave, significantly worsened cognitive tests.
The results – unique in their kind – show for the first time that the negative cognitive effects caused by the high temperature really exist.
In particular, 44 boys, divided between those who slept at night with air conditioning and those who were not, were ttoposti on cognitive tests for 12 consecutive days, still waking up, thanks to the use of the smartphone. During the tests, the researchers monitored various parameters, including: temperature, carbon dioxide levels, moisture content. They also found data on the physical activity and quality of children's nighttime sleep.
The results obtained have shown that high temperatures can deteriorate performance. During heat waves, students without an air conditioner actually did worse than their peers. Cognitive responses were slower than 13.4%, and also the calculation texts and those based on color and word recognition gave lower scores.
It is interesting to note that the most significant difference between the two groups was observed during the recharge period, that is when the outside temperatures began to decrease but that internal temperatures remained unchanged because the rooms were not equipped with air conditioning . Extreme heat has serious consequences for public health. To understand the extent of the danger, just think that it is the leading cause of death among meteorological phenomena
Yet, on the one hand, as this study has shown , the air conditioning is essential to the proper functioning of the brain, on the other hand, it has a great influence on the pollution of the environment.
Researchers at the University of Wisconsin-Madison predict up to 1,000 additional deaths annually in the eastern United States because of the high levels of air pollution caused by the disease. increase More specifically, the study predicts 13,000 human deaths a year caused by higher levels of particles in summer and 3,000 by ozone in the eastern United States in 2050
. Most of these deaths will be attributable to natural processes such as atmospheric chemistry and natural emissions, which are influenced by increased temperature. However, about 1,000 of these deaths would occur each year due to the increase in air conditioning fueled by fossil fuels.
"Climate change has arrived and we will have to adapt. But air conditioning and the way we use energy will worsen air pollution, while temperatures will continue to rise, "says David Abel, lead author of the new report.
