High Altitudes
and Hypothermia
By Jack Reardon
With the New England ski season about to
jump into high gear, a few timely
reminders about safe and healthy skiing
would appear to be in order. Safe skiing
does not just relate to how you comport
yourself on the slopes. Preparing your
equipment properly (i.e. having bindings
checked, ski edges ground, etc.)
certainly is important and we tend to
take care of this issue without much
second thought.
In February and March two groups of club
members will be heading for the high
country. Park City, Utah and Jackson
Hole, Wyoming. Both top out at
approximately 10,000 feet, or three to
four times the altitude at which we sea
level types usually ski. Everyone should
be aware that there is an inadequate
concentration of oxygen in the air at
higher altitudes, and that we require a
periods of time to become acclimated.
Needless to say, we all accomplish this
adjustment differently. When body cells
do not receive enough oxygen, a condition
called hypoxia can develop to one degree
or another. Everyone experiences some
breathlessness and rapid breathing or
even an elevated heart rate. A general
malaise or vague feeling of physical
discomfort will sometimes develop the
first day or so. We can forestall, or at
least minimize, this condition by
drinking lots of water and eliminating or
limiting the use of alcohol during the
period of adjustment. (This is also good
advice for long plane trips.) Taking it
easy while you get to know the mountain
is also good advice.
Prolonged exposure at any altitude to
cold temperatures or a cool, damp
environment can cause you to lose body
heat at a faster rate than your body can
generate it. Wearing proper clothing,
(layering is best) protecting hands,
feet, ears, and nose, and wearing a
helmet or warm hat can go a long way
toward preventing hypothermia. If you
feel a chill, take a break and warm up.
Also, you and your skiing partners should
keep an eye on one another for the
telltale white spots on exposed skin, a
definite precursor or frostbite. In all
cases relative to the prevention or
treatment of anoxia or hypothermia, the
use of alcohol or tobacco is to be
avoided.
Choosing underclothing of the proper
material is also very important. Cotton
is definitely a no-no for socks, long
johns, and undershirts. Cotton absorbs
perspiration, retains it, and does not
wick it away. Synthetic materials, wool,
and even silk are recommended. There are
many clothing items available that are
made from combinations of materials,
which do a great job of keeping you, dry
and warm.
Well, there you are…. just a few things
to consider. Remember, keep your eye on
the other guy…ski safely…and have a
great ski season!
