Horses are highly susceptible to heat stress due to their large size and limited ability to dissipate heat (Journal of Equine Veterinary Science [1]). As temperatures rise, equine professionals and horse owners to must be well-informed on how to keep their equine companions cool and comfortable during the sweltering summer months.

In this blog, we will explore effective strategies, backed by research and expert advice, to help you maintain the well-being of your equine companions. By sharing these tips with your clients, you can ensure that horses stay safe, healthy, and happy even as we head into the peak of British summertime.

1. Provide Ample Shade:

• Create shaded areas in the pasture using trees, shade cloth, or run-in sheds.
• Position water troughs and feeders in shaded areas to minimise sun exposure while animals eat or drink.
• Consider using fly sheets with UV protection to shield horses from direct sunlight.

2. Ensure Constant Access to Fresh Water:

• Horses need to drink plenty of water to stay hydrated and regulate their body temperature.
• Clean and refill water troughs regularly to prevent algae growth and ensure freshness.
• Consider using automatic waterers or multiple water sources to ensure horses have continuous access to water at all times.

3. Adjust Turnout Schedules:

• Schedule turnout during cooler parts of the day, such as early morning or late evening, to avoid peak heat hours.
• Provide access to shaded areas in the turnout space for horses to rest and cool down.
• Monitor horses closely during turnout for signs of heat stress or exhaustion.

4. Use Fans and Misters:

• Install fans in the stables to improve air circulation and provide a cooling breeze.
• Utilise misting systems or sprayers to cool down horses during extreme heat, especially after exercise.
• Ensure the misters are set at a comfortable pressure and positioned correctly to prevent causing stress to the horses.

When horses become overheated, they are at risk of developing various heat-related illnesses, including:

1. Heat Exhaustion: When horses are exposed to high temperatures and humidity for extended periods without proper cooling measures, they may experience heat exhaustion.
2. Heat Stroke: Heat stroke is a severe and potentially life-threatening condition. It occurs when a horse's body temperature rises to dangerous levels, exceeding their ability to regulate it.
3. Dehydration: In hot weather, horses lose significant amounts of water through sweat. If they don't have constant access to fresh water, dehydration can occur rapidly. Dehydration can lead to reduced performance, electrolyte imbalances, kidney damage, and other health issues.

If owners are concerned about the health or comfort of their horse in the heat, it's always best to move them to a cool and shaded environment and seek veterinary advice immediately.

Signs of Heat Exhaustion:

• Excessive sweating
• Rapid breathing
• Elevated heart rate
• Weakness
• Dehydration

By keeping horses cool and preventing overheating, you can mitigate the risks of these heat-related conditions and maintain their overall health. Implementing proper cooling strategies, providing shade and fresh water, adjusting turnout schedules, and using fans or misting systems are all effective measures to help horses regulate their body temperature and avoid heat-related illnesses.

Remember, proactive measures and attentiveness to your horse's well-being are crucial during hot weather. Regular monitoring, providing a suitable environment, and seeking veterinary care if necessary are vital steps to ensure the health and comfort of your equine companions.

1. Heat stress can be a serious concern for horses during the hot summer months. It is crucial to prioritise their comfort and well-being by employing proper cooling techniques.
   
2. Access to shade, ample fresh water, and well-ventilated areas are essential for maintaining horses' body temperature within safe limits.
   
3. Adjust turnout schedules and exercise routines to avoid peak heat hours and provide adequate rest for horses.
   
4. Use fans, misters, and other cooling systems to create a more comfortable environment for horses, particularly during intense heat or after exercise.
