I've actually been one to sweat no matter the time of year. Even when I was younger and thinner I was always a sweating (face/head mostly). I'm also one you would NEVER catch wearing a winter coat. I think the last time I wore one was about 25 years ago as a long sweater is the most I'll do. LOL
I was hoping that surgery would take care of that for me. Nothing worse than just walking normal with no real effort and then being the only one around with their face soaked and flushed. I HATE IT! Constantly being asked, "Are you ok?" Bleh
Anyway, since surgery and losing what I've lost so far (34.9 since surgery but 53.4 total since March), I've noticed I'm not really sweating in the kitchen as much as I used to or when doing housework. I've taken a few long distance walks outside in the heat and have NOT been overwhelmed like I used to be. No huffing and puffing and sweating. Usually I was the only one in the house who was still hot even though the air is on 67 but now at times I find myself being cold and putting the air up higher. I'm still early in the game so we'll see if this is long lasting. I hope it is!!
As for being in the the heat, the stomach and water.........I've noticed a few times if I do not eat, or have eaten hours prior to going outside to do yard work or even to just lay out or swim, I start feeling sick to my stomach. But now I try to at least eat a little something before going in the heat and I'll also drink something like Gatorade when in the heat instead of just plain water. I find that that helps a lot!
