The notion that a hot, recently exercised horse needs to walk until they are completely cooled off is a myth. A 2020 study found that out of the five methods tested, the quickest way to return to normal body temperature was stationary with continuous tap water application. This doesn’t mean that you should abruptly stop exercise—finish your ride or training session with a slow walk to allow your horse’s heart rate and breathing to gradually return to normal, but after that your sweaty, hardworking horse should be offered a cool shower and drinking water (small but frequent amounts) without delay.
Overall, enjoy your summer rides but be aware of signs of heat stress in your horse. When heat and humidity soar, even moderate exercise can push your equine friend’s body temperature beyond safe limits! Be sure to contact your veterinarian for more information about heat stroke and for recommendations tailored to your horse’s individual situation.
