<div dir="ltr"><div>AAAAAH Ok thanks steve!</div><div>I (hope) I haven't been hiding trying different ways to get in shape. Just to make sure what the guides sugested (as I only have one scarf) to show a little early wich is just done anyway for a new club. and wet it with cold waterdrape over my head for a a little bit. Then re wet the scarf. I thought with long hair or something a bit of tap cool water in the hair and on my head may help in someway.</div><div>The scarf around a neck trick is a oldish but helps.

<p>There is always a lot of blood flow between the heart and the
brain which passes through the neck, fairly close to the skin.
Among the many things blood does, is act as a working fluid to try
to help thermoregulate the body... passing hot blood near the
surface of the skin where evaporation of sweat is cooling the
skin... The neck would be an obvious place to apply extra
external cooling efficiently. <br>
</p>
<p>As with a cool cloth on the head, I think there is a perception
issue involved, meaning that when you are overheated, cooling the
region of your body you associate with "self", likely *feels*
better than say, cooling your feet or your glutes... provides
quicker apparent relief.</p>
<p>I'm aware of the type of fabric you speak of, but have never used
or inspected any. I'm assuming it somehow manages to *both* hold
enough water to not evaporate away immediately but at the same
time, have enough surface area (microstructure) to allow for a lot
of transpiration. Why "snapping" it abruptly works to
(re)improve it's cooling potential isn't as obvious to me, I'm
betting it has been written up many times in everything from the
popular press to academic journals in material science... time to
practice more Google-Fu?</p>

Something to do with with the neck (for example)
helps with body heat and the wraps let off cold
water...</div>
<div>I guess I just don't understand how something
that small can help cool you down. So I just

<div dir="ltr">Are you getting overheated during
class? I would assume that your teacher is
suggesting this as a way to help keep cool.
Evaporative cooling is especially effective in
dry climates like Santa Fe. See <a href="https://en.wikipedia.org/wiki/Evaporative_cooler" rel="noreferrer" target="_blank">https://en.wikipedia.org/<wbr>wiki/Evaporative_cooler</a>.</div>

trying out doing more excersize. In one
of my zumba classes a teacher sugested I
try a wet towel on my head (before
class) and then a wet scare around my

<div>I feel as my googlefu skills are
failing because I can't find a reason
why that helps. Anyone know what the
science is? </div>
<div>LifeHacker and a pretty dated
StackScience blurb speculated it has
to do with having just enough gold
water (relative to the hot air neer
your body) to somehow make kind of
cool air zone.</div>
<div>Somehow how I am...skeptical </div>
<div>Cooling of your head makes sense
(hair gets wet and you cold water on
your head just feels really good in
the summer)</div>
<div><br>
</div>
<div>But I don't get why cold towel or
scarf around your neck can help.</div>
