The con­di­tion

Your Horse (UK) - - Horse Care -

Heat stress re­sults from your horse not los­ing heat by sweat­ing ef­fi­ciently enough to cool him­self down. A typ­i­cal Bri­tish sum­mer day won’t af­fect your horse if you’re work­ing him at a leisurely pace, but if tem­per­a­tures are high and the ex­er­cise is stren­u­ous, then he’s at risk of de­vel­op­ing it.

Some­times known as heat ex­haus­tion, heat stress strikes for a num­ber of rea­sons, such as a raised am­bi­ent tem­per­a­ture. To re­move ex­cess mus­cu­lar heat after in­ten­sive ex­er­cise, your horse sweats, pulling the heat from his in­te­rior to the skin sur­face, to help to re­duce his over­all body tem­per­a­ture. Horses nor­mally sweat ef­fi­ciently over a large sur­face area, but heat stress de­vel­ops when they can’t dis­si­pate heat fast enough. There is on­go­ing in­ter­est as to whether some horses are ge­net­i­cally more prone to the con­di­tion, but not enough re­search has been done to con­firm this.
