To effectively cool down a hot horse the debate has been to scrape or not to scrape. Science of thermal regulation says not to scrape. Keep hosing!

Sweat Scraping Horses During Cool-Down: Why the Myth Persists and What Science Says
For generations, horse owners and many professionals have followed the traditional practice of sweat scraping — using a rubber or metal tool to remove excess sweat or water from a horse's coat after exercise. One of the most enduring beliefs tied to this practice is that you must sweat scrape to help your horse cool down properly, especially after hosing them off in hot weather. But is this actually true?
Let’s take a closer look at the origins of this belief, what modern science says, and whether sweat scraping is still necessary.
The Origin of the Myth
The myth likely stems from a time before we understood thermoregulation in horses. It was commonly believed that leaving water or sweat on a horse would trap heat and slow cooling. Sweat scraping became routine, especially in barns without good airflow or with heavy-coated horses that took longer to dry.
The logic seemed sound: remove moisture quickly to speed up cooling and prevent chills or overheating. Over time, this practice turned into a widely accepted rule — even though equine science has since moved on. I actually remember having to do it for my BHS exam.
What Really Happens When You Hose Off a Hot Horse
When a hot horse is sprayed with cool water, the water absorbs body heat and then carries it away as it runs off or evaporates. This is the primary method by which water cools the horse — not by being scraped off immediately.
Key point: The cooling effect comes from the transfer of heat from the horse to the water, not from how fast you dry the horse.
In fact, studies (including those conducted by the University of Queensland and other equine researchers) have found that continuously applying cool water over the horse’s body is the most effective method of reducing core temperature — especially during hot and humid weather. This technique is used in endurance riding, racing, and eventing, where managing a horse’s temperature is critical.
Should You Still Sweat Scrape?
The short answer: Not necessarily — and certainly not to help cooling.
Here’s when you might still want to sweat scrape:
• To remove excess water after hosing if it’s cool out and you want to avoid your horse staying soaked.
• To prevent water from pooling under tack or rugs.
• To help speed up drying if your horse is going back into a stall or needs to be groomed quickly.
But if your goal is cooling the horse, especially in hot conditions, scraping is not required and may actually interfere with the cooling process if it interrupts cold water application.
The Takeaway: Let Go of the Myth
Despite decades of tradition, the idea that you must sweat scrape a horse to help them cool down is outdated. Cooling a horse effectively is about keeping cold water flowing over their body, not about drying them quickly.
In fact, many top equine veterinarians now recommend leaving cold water on — and reapplying it repeatedly — during a cool-down after heavy exercise, especially in summer.
So the next time someone says, “You have to sweat scrape to help them cool down,” you can confidently — and kindly — explain that it’s no longer supported by science.
In Summary:
✅ Cold water helps cool the horse by absorbing heat.
✅ Reapplying water is more effective than scraping it off.
❌ Sweat scraping is not necessary for cooling.
✅ Scrape only if you want to speed drying or reduce discomfort ( for example some horses dont like the feel of dripping water, but most shake and have a roll afterwards ).
It's time to move beyond tradition — your horse will thank you for it.
