Cooling Down in Very Hot Weather |

Riding when the temperature
is well in excess of 90 degrees can be
dangerous to your health. Unless you take
care to keep your body temperature under
control even rides as short as an hour can
result in heat-prostration or even
sun-stroke.
Many riders know that if you keep your
neck cool, because the large veins that
feed your brain are so close to the
surface, you greatly diminish these
health risks. There are two very popular
devices that are simple and effective in
this regard.
One is called a 'cool collar' and is
made from a tube of bandana material
that contains some water absorbing
beads sewn into it. The beads
increase in size about 50 TIMES over
when they are dry. Thus, when dry,
these collars store easily and take
up very little room. But getting
them wet is not as easy as it
sounds. That is, you have to take a
dry collar and submerge it in water
for up to 1 hour before it has
absorbed all the water it can. That
hour is often not available to you
when you need it.
The reason the collar works to
cool you off is that it takes
even longer for the beads to dry
out than it did to get them wet.
That is, water will evaporate
from them over a several hour
period. Any evaporation activity
cools - but only marginally so
from the wearer's point of view.
That is, within half an hour of
putting one of these collars
around your neck, even if it had
been in a freezer before you put
it on, the collar will be very
nearly at the temperature of the
air around it.
Far better than these 'cool
collars', I have found, is
the original design of them
(sometimes called 'Kool
Kollars'). These are usually
made of terry-cloth sewn
together in such a way as to
contain a pocket into which
a zip-lock bag is placed.
These are filled with ice!
This type of collar REALLY
cools your neck as the ice
melts, AND they drip cool
water. That dripping leaves
the front and back of your
shirt sopping wet over time
which provides a huge source
of evaporation - i.e., it
helps to COOL!
At every pit stop you
make you can refill the
'Kollar' with ice (just
pour in a glass of ice
water, ice and all).
The bead filled
collar cannot be
rapidly cooled again
once it has gotten
warm. Thus, you
usually find that
people that use them
have two - one of
which is always
sitting in an
ice-chest.
One more way to
handle high heat
- those of you
that wear
skull-caps
(helmet liners)
can simply
saturate them
with water
before putting
them on. This
works very well
indeed, for
about half an
hour.
Further, of
course,
simply
pouring
water on
your shirt
helps a
great deal -
again,
because it
provides a
huge area
over which
evaporation
takes place.
