The summer has begun with exceptionally high temperatures affecting much of Europe. In several areas of the continent, 40 degrees have already been exceeded. What worries experts is not only the intensity of the heat, but above all its persistence: this heatwave could in fact last a long time, becoming one of the longest-lasting in recent years.
In many Italian regions, maximum temperatures have risen well above seasonal averages, with deviations that in some cases reach up to ten degrees. Similar conditions are also being recorded in other European countries, from Spain to Germany, where extreme heat continues to put citizens, infrastructure and services under pressure.
Faced with this scenario, several governments have introduced measures to reduce the risks linked to high temperatures. Attention is particularly focused on workers most exposed to heat, such as those employed in agriculture, construction and other sectors requiring physical activity under the sun. Extreme temperatures can directly affect health and the ability to perform work safely.
Extreme heat and cognitive performance
@reuters Temperatures are set to climb across Europe, with a projected 104 degrees Fahrenheit across parts of France, while Northern Europe including Belgium and the UK are expecting temperatures over 86 Fahrenheit and even hotter in the coming days, as seen in a graphic. The heat surge on June 21, the summer solstice in the northern hemisphere and typically the start of the three hottest months of the year, raised concerns of an early and persistent onset of extreme conditions, prompting nationwide warnings, transport disruption and signs of strain on wildlife and at tourist hotspots. #europe #heatwave #france #italy #belgium #climatechange original sound - Reuters
For a long time, heat was believed to affect concentration and mental efficiency, but this assumption was based mainly on everyday experience rather than on in-depth scientific data. Only in recent years have researchers begun to systematically study the relationship between high temperatures and cognitive abilities, trying to understand their real effects on people.
Early research has focused mainly on the most vulnerable groups, such as the elderly. In these individuals, heat can lead to dehydration, sleep disturbances and physical stress conditions that may compromise overall well-being – especially for those living in urban areas. However, scientists have also begun to question whether similar effects may occur in young and healthy individuals.
One of the most significant studies in this field was conducted in the United States by Harvard University and involved a group of university students: researchers observed their behavior and performance in different environments, comparing those who had air conditioning with those living in buildings without cooling systems – and the results were quite striking.
The effects of extreme heat on the brain
During the observation period, students were subjected daily to tests assessing attention, memory and reasoning ability. Participants living in hotter environments showed lower performance compared to those who benefited from more comfortable thermal conditions.
These findings suggest that extreme heat is not only a physical well-being issue, but can also affect activities requiring greater concentration. The researchers’ conclusions open a broader reflection on climate change and the effects of prolonged heatwaves. If summers continue to become longer and hotter, the impact could extend far beyond individual discomfort, with potentially significant consequences for the economy and the organization of daily activities.
