As temperatures soar, it's not only humans who have to cope with excess heat and humidty; but horses, who are better adapted for cool climates than scorching ones, are also being challenged by the heat.

When humidity is high and sweat no longer evaporates to cool the skin, horses are prone to heat exhaustion and heat stroke which can be extremely dangerous.

Despite their ability to sweat, a relative rarity among animals other than humans, horses have difficulty cooling themselves when temperatures become extreme.
Because of their large size, their body heat tends to accumulate faster than they can get rid of the excess.
Especially in conditions where humidity is high and sweat no longer evaporates to cool the skin, horses are prone to heat exhaustion and heat stroke which can be extremely dangerous.
6 tips for keeping horses cool:
- Exercising only in the cooler temperatures of early morning or late evening
- Turning horses out at night and giving them shelter from the sun in the barn during the day
- Ensuring there is always access to clean, cool water (keep in mind that outdoor troughs will heat up quickly out in the sun, so it’s smart to change the water daily during the summer)
- Spraying the horse with cool water
- Making sure horses have access to good ventilation and shade
- Using ceiling or box fans to help keep air circulating.
When all this is not enough, horse owners might want to consider the cooling properties of a misting system or evaporative cooling fan.
A misting system, when installed in a barn, introduces a steady supply of water to the air in the form of ultra-fine droplets which evaporate before they hit the ground.
A correctly installed misting system creates a curtain of mist, which can reduce temperatures in the immediate area by as much as 20 to 30 degrees Fahrenheit, depending on the outdoor temperature and relative humidity.
In addition, a misting system repels flying insects and reduces the level of dust and airborne particles in the environment, making it beneficial to equine respiratory health.
For horse owners who don't want to take the time or spend the money to install a misting cooling system, evaporative cooling or the use of fans stimulates air movement and provides some comfort when horses come in direct contact, although fans are less effective in cooling the immediate area.
