Heat Stress in Horses – Advice from Your Veterinary Team
As temperatures rise in the UK, horses can quickly become vulnerable to heat stress, especially during exercise, travel, or turnout with limited shade.
Unlike humans, horses generate a lot of internal heat when working and rely heavily on sweating to cool down. When conditions are hot and/or humid, that cooling system can become less effective.
Remember: humidity, lack of breeze, travel stress and workload can make even “mild” UK temperatures dangerous.
5 Ways to Help Prevent Heat Stress in Horses
As temperatures rise, it's important to keep horses cool, comfortable and safe. Heat stress can develop quickly so close monitoring and good management is key.
Horses are less efficient at regulating their body temperature, particularly under exertion or stress. Prevention is always better than managing heat-related illness once it develops.
Keep a close eye on your horse during hot spells and act early if you notice any changes in behaviour, breathing, or energy levels.
Heat stress in horses: signs every owner should watch for
If you notice any of these signs, stop exercise immediately, move your horse to a shaded, cool area, and begin cooling with applications of copious quantities of water, while seeking veterinary advice.
Severe heat stress can escalate quickly and early action makes a significant difference.
