As I get older, I'm now approaching 56, I find that I am not acclimating to warmer weather as quickly, and this year almost not at all. Today, at this time, it is 75 outside with 31% relative humidity and inside my house is at 56. I need to get more yard work done, but I'm breaking out into a significant sweat an am quite uncomfortable when outside---to the point where I'm feeling a bit of heat exhaustion. My exertion level is quite low trying to get the yard work done, compared to shoveling snow in the winter (where I'm quite comfortable). While inside, cooling off, I'm still sweating and not really feeling cool, but at the warmer end of comfortable.
I'm not overweight by any standard measure, for I stand at 5'7" and weigh about 143 (+/- 3) pounds.
When I go for my physical (once I get employer provided insurance again), what should the doc be looking for: thyroid issues, metabolic issues, other stuff? Or, do I need to move to Northern Alaska?
Are there things I can do in the mean time to help? I drink plenty of water, and will add Gatorade to replenish salt and potassium, along with eating regular potato chips.
