My guy has anhidrosis, so I’ve ridden exactly once since early June. It’s been one of the worst summers I can remember, and it’s always hot and humid here (Eastern NC) in the summer, but it has been relentless this year. More days with 100+ heat index than not since mid-June.
My gelding is now in from AM feed until after PM feed. He has good airflow in his stall and a good fan. He stays comfortable. I check at lunchtime/early afternoon and refill his water, add some hay if needed, and pick through his stall. After PM feed, if it has cooled down (often get thunderstorms blowing through or brewing nearby that bring clouds, showers, and breezes) I just turn out with fly mask and boots for the evening (can always go back in stall if he chooses). If it’s still blazing hot (seems like 4-7 PM is the hottest part of the day if there are no storms around) I hose down thoroughly, then put on fly mask and boots.
He’s currently getting One AC, Guinness, a second round of EquiWinner patches, and the Chinese herbs meant to help with anhidrosis. And he had acupuncture a few weeks ago. I literally am doing everything possible to keep him cool and help him sweat besides sell him to a cooler climate home (which ain’t happening!).
As for me. I’m 51, going through perimenopause, and have no thyroid. I sweat BUCKETS (wish I could give this ability to the horse). I just stay hydrated and take breaks in front of the fans as needed. I’ll hose down my arms and legs and hair if needed. And then I get back to the world of air-conditioning as soon as Himself is appropriately cared for.
