Re: Heat and BP
I'm with Uff-da; I find that a hot room always lowers my BP to a very nice, or super nice level.
As zuzu explains, in order to lose heat the body dilates it's skin's arterioles so the skin is flush with "hot" blood and the process radiates away. It's analagous to opening all the spigots in an old house, the pressure falls.
I find exactly in the winter: When I am chilly, my BP always soars...the skin circulation is shut down to a bare minumum.
I haven't notice much change with eating normally but my BP goes up a little with a HUGE meal. I theorize that if the stomach needs extra blood-flow for digestion, it might well clamp down on the skin and brain...might also explain full-stomach-sleepiness.
