Extreme heat – why are people feeling more tired during this heatwave?

Record high temperatures are anticipated for England and Wales this week, as the region braces for a second significant heatwave of the year. Forecasts indicate that local temperatures could reach as high as 39 degrees Celsius, suggesting a period of hot days and challenging nights for residents. Meteorologists caution that the actual recorded temperatures may not fully convey the intensity of the heat.

They advise that the perceived warmth can be amplified by several environmental factors, including high humidity levels and the absence of sufficient nighttime cooling. This combination can make the heat feel considerably more severe than the thermometer readings alone suggest. The mechanism responsible for such intense weather patterns is often related to a phenomenon known as “weather blocking,” which can trap high-pressure systems over an area.

Consequently, the combination of persistent high temperatures and increased atmospheric moisture can lead to significantly elevated “feels like” temperatures. For instance, a measured temperature of 35 degrees Celsius could feel equivalent to around 41 degrees Celsius when factoring in high humidity and tropical night conditions. Residents are advised to prepare for these challenging conditions.

While the official temperatures provide a baseline, understanding the role of humidity is crucial for gauging the true impact of the heatwave. These sustained periods of elevated temperatures necessitate careful attention to hydration and heat safety protocols to ensure public well-being during this period of intense weather.
