Staying Cool: US Equestrian’s Heat Safety Guidelines for Competitions

A few weeks ago, US Equestrian shared essential guidelines for managing severe heat conditions during equine competitions, based on the American Association of Equine Practitioners (AAEP) heat index guidelines. It’s important to note that the AAEP’s heat index, calculated as the sum of temperature plus relative humidity, differs from the National Weather Service’s more complex formula. To ensure clarity and safety, these guidelines emphasize the necessity of evaluating specific conditions and taking appropriate measures. For instance, when the heat index is below 130, competitions can proceed normally. However, if the index falls between 130 and 150, participants should begin monitoring horses for signs of heat stress. Critical monitoring is required if the index is between 150 and 180, and if it exceeds 180, alternative competition times should be considered to avoid the peak heat.
Competition managers have a crucial role in mitigating heat risks. They should evaluate the venue’s heat risk factors, including shade availability, airflow, type of competition, and the number of horses participating. Implementing measures like increasing shade, improving ventilation, and ensuring ample water supply for cooling horses can significantly reduce heat stress risks. Continuous monitoring of temperature and humidity is vital, and if the combined heat index surpasses 180, it’s recommended to cancel or reschedule events to cooler parts of the day. Given that heat index values can fluctuate throughout the day and across different locations within the venue, consistent checks are essential.
According to Dr. Katie Flynn, it’s imperative to monitor the health of both horses and human athletes in hot weather. Staying hydrated and seeking shade or areas with fans is crucial for everyone involved. Signs of heat stress in horses include elevated temperatures, rapid breathing and pulse, stumbling, weakness, dry skin, and dehydration. If a horse shows signs of overheating, it should be cooled with water, provided fluids, and moved to a shaded or breezy area. If the horse’s condition does not improve within an hour or worsens, contacting a veterinarian is essential. By following these guidelines, participants can help ensure the safety and well-being of all involved during hot weather competitions.
Always Consult a Veterinarian If You Have a Concern.
Signs of heat stroke may range from mild to severe and life-threatening; they may include the following:
1) Temperature as high as 105 to 107 F
2) Rapid breathing, rapid pulse
3) Stumbling, weakness, depression
4) Refusal to eat or work
5) Dry skin and dehydration
6) In severe cases, a horse may collapse or go into convulsions or a coma
