I went walking for the first time in 3 weeks yesterday with hubby. We waited until evening so it was a bit cooler. We've had hot, humid weather. Lots of thunderstorms (what kept me inside at first, then the mood issues demotivated me.)
I could barely tolerate it. Made it through 20 minutes only by focusing. I felt so hot and weak, like I was gonna pass out. My legs were shaky. I was panting. I felt woozy.
I'll note that I did my Pilates session with my trainer and got through it fine. Indoors. With a/c. But the heat/humidity outside got to me. 8pm and it was overcast, humid, and in the 80s.
I walked fine all last summer, even in humid weather, and that was when I was a bit hypothyroid, so I was feeling "chilly", as hypothyroid folks will tend to when they are a bit out of range. I was comfy for the most part last summer, and enjoyed having a time outside.
I guess when I see the endo in July (regularly scheduled appt), I'll find out if she needs to tweak me. I want to be able to walk again, but it's a fine line where I am euthyroid, and it's hard to STAY there.
Heat intolerance is tough. I start hyperventilating, feeling weak, feeling like I'm gonna burn up and pass out. Hate it. Wish I had a normal thyroid and didn't have to keep adjusting meds with weight changes or after active thyroiditis incidents. Well, you do what you can and keep the faith that medical science progress improves the situation.
I miss walking now. Wish someone could follow me around blasting icy air. :D
