I have heard that once a person has had a heat stroke
, they can not tolerate the heat
anymore. It seems to do something to our body's chemistry.
I have not had a heat stroke, but, I am extremely heat intolerant. I am always hot, and I must be in the A/C or I get short of breath, PVC's and feel horrible. I am even hot in the winter.
One thing besides heat stroke that can cause heat intolerance is an over-active thyroid and also a lack of natural progesterone.
