Date: Mon, 12 Apr 1999 00:00:51 EDT
Kayakers,

I have read that for safety reasons you should be dressed for water 
temperature, not air temperature, when kayaking.  As a result, the authors 
say you should wear a wetsuit when paddling in cold water.  I wear a wetsuit 
when I know I am going to be in the water, such as when I am surfing and 
practicing rolling, sculling and bracing;  and when I am surfing, I find that 
I have to roll about every 5 minutes to cool off.  I couldn't imagine wearing 
a wetsuit on a regular paddle, because it is too hot.

Hasn't anyone considered the risk of heat cramps, heat exhaustion or even 
heat stoke from paddling while wearing a wetsuit?  I saw a lot of guys suffer 
from overheating injuries when I was an airborne infantryman in the army, and 
it is as serious and deadly as hypothermia.  As a result, when touring I 
think it is better to dress for air temperature and to be prepared for 
capsizes by developing good rolling and reentry skills to minimize time in 
the water.  I would rather risk the rare occurrence of getting hypothermia 
from being in the water for a prolonged time than risk getting overheated 
everytime I paddled by wearing a wetsuit.  For most touring paddling it is 
nonsense to be dressed for water temperature rather than air temperature.

Your input is encouraged!

	Duane,

		I was a Boiler Technician in the Navy-14 years.  During that time I was
exposed to high temperatures for long periods of time.  The solution seemed
to be to "stay hydrated..." oh, and maybe "push a bit less..."  

	When I was out paddling summer before last, I tried to let the water temp
determine how I was dressed-and let the air temperature determine how large
my stock of fluids should be...  That meant dry-top and wet suit in the
summer...

	This past fall and winter, well, It's been poly underwear and a dry-suit
even though fortunately, I have not gotten more than my feet wet...<G>

	I believe that your concerns about "heat illness" are valid, but I also
believe there are ways around that while limiting the risk potential...

FWIW,

	Tom... in Renton, Wa.

There are trade-offs, for sure.  Your point about only needing a level of
immersion protection to cover the probable time in the water to achieve
reentry is well taken.

One option is to adjust your wetsuit/dry top combination to fit the water
temperature, rather than wearing a full-tilt heavy wetsuit all the time. 
If you wear a 3 mm farmer john as the basic immersion protection, ramp up
with a dry top as the water gets colder, and add fleece as the water gets
colder yet, you can generally avoid overheating problems, at least where I
paddle. (Yesterday I paddled under a waterfall to cool off -- worked
great!)

In sunny SoCal, perhaps this would not work so well as up here.  I will
admit to having discarded the dry top on really hot days, when I might have
needed it if I capsized.

As another poster mentioned, hydrating yourself well will avoid most
overheating problems.

You have raised a good issue.

Besides staying well hydrated I had a chance to try a trick I had read somewhere a few weeks ago.  I was floating down the Kansas River in air temps around 70 F while the water was probably around 45 F.  Everytime I started to feel hot I would drag a hand through the water for a little while, basically using the hand as a small radiator to cool my blood and hence the rest of me.  Worked wonderfully.  I ended up with wet neoprene gloves but overall cooled off.  :)

I have had the experience while participating in a SCUBA Instructor course.
We were required to swim several miles at a "race pace" in full wetsuit in
relatively warm water.  The result was cramps which left our muscles,
particularly the large muscles in the legs, sore for about a week.

I tend to run hot, and have on more than one occasion suffered heat 
exhaustion (or was it heat stroke; I always mess them up). But never
paddling. I just don't generate the same heat with paddling as I would using
the much bigger muscles of the body. I've never paddled water anywhere in
California, ocean or river, where I felt the water was so warm that a
wetsuit was a threat, although I've gone without one many times. I could
stay out in the SoCal water for hours, for example, in the summer without
hypothermia, but I've also done some long swims in that same water with a
wetsuit with no problems except for some discomfort. I use a farmer john,
however, which definitely allows for more venting. I have diver friends who
use those urethane/pile garments even in tropical water; they look like they
might work for those that run real hot.

At first I thought you were trolling, Duane, but everyone else is 
taking your post seriously, so I will too.  Sorta.

Your logic is good: my limited experience in Southern California 
and the Baja says that the water is never very warm, and, "... when 
[you] know [you're] going to be in the water ..." a wetsuit is 
probably needed for comfort and probably for survival on any 
extended swim.  So when you're going to be swimming, you wear a 
wetsuit and rotocool for to avoid hyperthermia.  My question is this: 
how do you know when you are going to be in the water?  Do you 
know for certain that you won't get wet on any given day?  If you 
can always predict when you are or aren't going to swim --- and if 
your life might depend on this kind of accurace, which it might --- 
I'd like to know if you do any consulting on lottery tickets and at 
horse tracks.

Seriously, you acknowledge needing a wetsuit when you're going 
to swim, but how do you know you aren't?

Jack Martin
