For so many of us, we were at one point taught to use cool water 💦 to cool down our horse, but then to make sure we immediately scrape it off to make sure the horse stays cool. Dr. Marlin, a thermoregulation specialist, researched differently!
When we put water on our horses, there is often a conduction of heat from the horse to the water, which is why the water often becomes warm. Dr. Marlin studied that when there are two bodies in contact, they often transfer heat 🥵 to become the same temperature, which is what is taking place when the heat from the horse is leaving the horse and heating the cool water that we are placing on them! As a result, the cool water is absorbing the heat from the horse, removing it from the horse, allowing the horse’s temperature to drop!
In the summer, this means scraping a hot horse is actually slowing the cooling process, taking the conduction property of the water away. However, in the winter, it is important to scrape the horse when using water, as the cool water will cool the horse’s body temperature to match the water, inadvertently making the horse colder!🥶
