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

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.
