There's a lot of old horsemen's myths still running rampant today.
Some are harmless, but others - well it seems like they really should be debunked but some people insist on still believing them.
Since it's

After you hose your horse off, do you scrape the water off or no?

MYTHS
Myth 1 - “You should never put cold water on a hot horse"
Explanation - Ice-cold water(0-5°C) on hot horses does not cause shock, laminitis, kidney damage, muscle damage, tying-up or heart attacks!

Myth 2 - “Water left on a horse will heat up and insulate and make the horse hotter."
Explanation - Flawed physics! Water is a better conductor of heat than air. A wet horse will actually cool faster than a dry one, even if humidity is 100%.

Myth 3 - “Scraping is essential." Explanation - Scraping just wastes time that could be better used putting more water on to cool by conduction. Scraping also wastes water when water is in short supply. Water which could evaporate on the horse. Water evaporating on the ground doesn't cool horses down.
Myth 4 “Concentrate on large veins, arteries inside the back legs, large muscle groups"
Explanation - NO. Cooling by evaporation or conduction works by cooling the blood flowing through the small blood vessels in the skin. The more skin you cool, the quicker you cool the horse. Apply water all over.

I'll admit, I followed the old rule of always hose, scrape, hose, scrape for a long time until I read the actual science behind it. How would I have known any better? But now I just keep hosing Hampton, and then turn him right back out. In the sun! *gasp* No scraping anymore. Here's more:
Evaporation and conduction.
Ideally, I would hose Hampton and then let him sit under a fan for a while. I mean think about it - when it is 95 degrees, and you splash water on your face or over your head, do you get hotter or do you get a cooling effect?
So there's no harm in the hose, scrape method. But it seems a little pointless.
What method do you follow?
