Re: [RC] General cooling with water - desertrydr1The other thing is that water has a--Heidi will know what I'm talking about--When I lived up in Fairbanks, AK, the temperature would start dropping in the fall. Unless it just suddenly plunged to -30 or something, the areas near water, like the Chena River that runs though the middle of town, would stay warmer longer. It was because water takes a long time to give up it's heat when it's in a bigger body. It gives up its heat into the air which keeps the air warmer closer to the water. Basis of all the life on Earth, the ablilty to keep the temperature more stable within a range that could foster life, something like that. Anyway, what it means is that water is a really good insulator and can absorb a lot of heat for each degree of temperature rise in the water. So when you put new water on the horse, it picks up some heat which you can get rid of by getting rid of the water. I don't think it has as much to do with the hair as insulator.jeri -----Original Message----- From: Sheila_Larsen@xxxxxxx To: heidi@xxxxxxxxxxxxxxx Cc: ridecamp@xxxxxxxxxxxxx Sent: Thu, 13 Nov 2008 8:51 am Subject: RE: [RC] General cooling with water Yes I understand the evaporation process but my recollection is that the
water that is trapped between the skin and hair gets warm and does not
allow cooling as the water that you are then putting on slides down the
hair without pulling the water below the hair away from the body or pulling
enough heat away from the body . In think about this it is probably more
of a problem sponging then say hosing which may create enough pressure to
push the water away from the body. I admit I was surprised when I read the
article but when explained it made sense. So that is how I remember it and
again the reasoning wasn't intuitive. I imagine that evaporative cooling
would work over time but not for a quick cooling like you would want for a
very hot horse.

RE: [RC] General cooling with water
Sheila, it depends on the humidity. If the humidity is high, then very
little evaporation occurs, and the effect you describe is what happens if
you don't scrape the water off. If humidity is low, then evaporation
causes cooling.

In my post about cooling with ice I said that I put the water on and then
scrap it off. I do that but I thought I would pass on what I remember of a
study done of putting water on a horse. The take home msg was always scrap
the water off when using water to cool. If you leave the water without
scraping it off (and this is where my memory gets a little shaky) water
that is trapped between the hair and skin causes the heat to be retained
and you do not get the cooling effect that you should. That may not be
absolutely correct the the again the take home msg was cooling with water
and not scraping does not providing the cooling effect you may think you
are getting. I believe I read that in either Equus or The Horse.
