The UK is currently experiencing a heatwave, with temperatures reaching record highs. While staying hydrated is essential, many are wondering if a hot drink can actually help cool them down. It might seem counterintuitive, but research suggests that drinking hot beverages can indeed have a cooling effect.
Studies from the University of Ottawa School of Human Kinetics indicate that hot drinks trigger sweating, without significantly raising core body temperature. This sweat then evaporates, cooling the skin’s surface and reducing the sensation of warmth. So, while a hot drink may not provide instant, refreshing coolness like an iced beverage, it can help regulate body temperature.
However, this cooling effect is dependent on the environment and individual conditions. Ollie Jay, a researcher from the University of Ottawa, explains that the sweat must be able to evaporate for this cooling mechanism to work. In humid environments or when wearing heavy clothing, the sweat may not evaporate effectively, rendering hot drinks less beneficial. In such situations, cold drinks are a better choice.
Ultimately, the best way to stay cool during a heatwave is to stay hydrated and find ways to keep your body temperature down. While hot drinks can be effective in certain circumstances, it’s important to be mindful of the environment and individual needs.
So, the next time you’re feeling the heat, don’t dismiss the idea of a hot drink. It might just be the unexpected cooling solution you need.
