A significant heat wave is on the way, and itโs more than just uncomfortable, it poses a real threat to horse (and human) health. When both temperature and humidity climb, a horseโs ability to cool itself becomes compromised. The signs of heat stress can be easy to miss until they become dangerous, which is why itโs critical to go into these hot days with a science-based plan. Knowing how to reduce risk through smart management, recognizing the early signs of trouble, and understanding how to respond quickly and effectively can make all the difference. Prevention is always easier than treatment, so letโs stay ahead of the heat.
The first thing to consider is when it is acceptable to work your horse. There are two heat indexes commonly used: one was developed by the American Association of Equine Practitioners (AAEP) and takes the sum of the temperature (ยฐF) and relative humidity (%). The other was developed by the National Weather Service (NWS) and uses a more comprehensive formula. Considering the NWS guidelines are more conservative, I tend to follow their recommendations out of an abundance of caution.

๐ข 125: Use extreme caution and avoid any exercise or activity while implementing preventive and vigorous cooling measures.
While these recommendations can guide your decisions, remember that many individual factors may influence heat tolerance, including fitness level, age, hydration, ride intensity, and acclimation.

โข Panting or flared nostrils
โข Rapid or labored breathing at rest
โข Elevated heart rate that doesnโt recover after exercise
โข Lethargy, dullness, or unwillingness to move
โข Dry, tacky, or dark gums
โข Muscle tremors or incoordination
โข Increased re**al temperature
If you see any of these signs, act immediately, move the horse to shade, apply cool water continuously, and call your veterinarian if the symptoms persist.
Letโs be proactive, not reactive, and make sure our horses stay safe and supported during this extreme heat.
Stay cool everyone!
