This past weekend in the woods was beautiful except for one thing.
Although it was only 88 degrees, I felt as if I was overheated from
tromping thru the woods. Most of the time I was wearing a caving
helmet and I found that when I took it off I was much more comfy. In
the past, I have noticed I cannot wear any sort of hat in anything but
winter weather otherwise I overheat. Instead I wear a visor to block
the sun from my eyes. I have concluded that most of my overheating is
because my head gets too warm. It is no longer a matter of simply
being uncomfortable but has become a serious safety issue for me.
So, how much would getting a crew cut haircut help? Generally, I
think having some hair prevents sunburn. Those of you who have little
hair, how much do you burn? Does sunscreen help? Would a bandanna
soaked in cold water help. In the past, I have dunked a hat in water
to cool by evaporation and it helps some.
Your head dissipates much of the heat your body generates. There's a
product out there that is a tube of pellets that absorb water, then
you wear it around your neck. It helps to cool you neck, and the
blood that flows through it, to lower your body temp. Maybe that
would help?

Here's one of the sources:http://www.coolhats.com.au/cool_snakes.html

I do use the pellet tube thing and it sorta works and I also do what
Harry suggests, especially when canoeing in cold spring water.
Realizing it is mostly a matter of cooling my head two days ago has me
wondering if I can solve the problem while avoiding sunburn. Baseball
caps are too thick so I'd like something very thin made of cotton I
could dunk in cold water every few minutes, That on a nearly bare
head might be the solution.


My full brim hat is a cotton tilly. You can find lots of 'em he

Probably this model...mine is at least 15 years old, so there may have
been some changes, but it looks like this:
