1. Choose cooler turnout times. If your horse has a stall, but is turned out for part of the day, provide turnout during the cooler hours. 2. Provide shade. If your horse lives outdoors or if he must be outside during the day, provide relief from the sun. 3. Move the air. Fans are a great way to help keep the air moving in the barn, but use them wisely. 4. Mist your horse. Frequent mistings are far more effective than a single dousing with a hose. 5. Provide fresh, cool water
