Here in not-so-east Texas its simple,
after about 2 weeks you get adjusted to it.
So my advice is take it kind of easy for a couple weeks,
then ignore it (well as much as you can).
I'm real big on the hydration thing, 2 water bottles and
camelback 2 litre. One bottle filled with "sports drink" for
the electrolytes.
Interestingly I read somewhere that a helmet provides
more cooling (providing its well ventilated) than riding
with no helmet.
