Extreme Heat Stress: A Deadly Phenomenon Sweeping Europe
Poinews.com – Extreme heat stress is rapidly becoming a critical issue in Europe, as rising global temperatures reshape the region’s climate landscape. According to the Copernicus Climate Change Service (C3S), Europe has warmed by approximately 2.5°C since the pre-industrial era, making it the fastest-warming continent. This warming trend is intensifying the effects of heat stress, a condition that combines environmental heat exposure with physiological strain, threatening public health and ecosystems. Understanding what extreme heat stress is—and how it’s evolving—has never been more urgent.
Defining Heat Stress: More Than Just Temperature
Heat stress occurs when the body’s ability to regulate temperature is overwhelmed by environmental conditions. While traditional measurements rely on air temperature, scientists now emphasize “feels-like” temperatures, which incorporate humidity, wind speed, and other factors that affect human comfort and health. A recent study in the journal Nature highlights that extreme “feels-like” temperatures are not only increasing in frequency but also in intensity. These conditions, including tropical nights where temperatures stay above 20°C for extended periods, are becoming more common across Europe and beyond.
“Heat stress generally results from a combination of factors, such as high ambient temperatures, humidity, physical activity, and inadequate fluid intake,” says C3S. “Various elements influence the human body’s capacity to maintain a stable core temperature, which can lead to a range of health risks.”
Health Impacts of Prolonged Heat Exposure
Extreme heat stress can trigger severe health complications, particularly in vulnerable populations. When core body temperatures rise beyond safe limits, individuals may experience rapid breathing, excessive sweating, dizziness, and even heat exhaustion or heat stroke. The study categorizes heat stress into three
