With the UK heatwave in full swing, many people are searching for effective ways to stay cool. While drinking plenty of water is essential, a climate tech expert has revealed a surprising technique that athletes reportedly swear by: swishing peppermint in your mouth.
The Peppermint Trick for Instant Cooling
Alexander Matveenko, co-founder of Rainbow Weather and a climate tech expert, suggests that swishing peppermint and then spitting it out can trigger the body's built-in cold receptors, creating an instant cooling sensation from head to toe. This method is particularly popular among elite athletes competing in hot conditions.
Science supports this claim. A 2021 study published in the International Journal of Sport Nutrition and Exercise Metabolism found that athletes who used a menthol-containing energy gel during training reported a greater cooling sensation compared to those given a placebo. Another 2020 meta-analysis reviewed multiple studies and concluded that menthol consistently made participants feel cooler and more comfortable while exercising in warm conditions, and in some cases, improved endurance performance.
However, it is important to note that menthol does not significantly change core body temperature, sweat production, or heart rate. Instead, it alters the perception of heat, making you feel cooler without physically lowering your body temperature.
Other Ways to Use Peppermint for Cooling
Nutritionist and wellness coach Simone Thomas recommends peppermint as a natural way to cool down. She suggests growing peppermint in your garden or buying it cheaply at the supermarket. For those who dislike hot peppermint tea in warm weather, she recommends freezing mint into ice cubes or adding fresh mint to a jug of water for a refreshing herbal drink.
Staying Hydrated Without Nighttime Bathroom Trips
Sleep expert Maryanne Taylor advises eating water-rich foods like cucumber, watermelon, and celery to maintain hydration. She also recommends drinking more fluids earlier in the day and reducing liquid intake an hour or two before bed to minimise nighttime bathroom visits.
