I can only offer my own experience . I would sweat so much that I would soak thru my clothes. 20 minutes into my grocery shopping trip and my hair would be so wet it was embarrassing. I can remember trying to pick out a card for a friend and as I looked down I was dripping sweat on them. I eventually had hot flashes , and fanned myself constantly. During a visit with my endocrinologist, I mentioned these things . I thought I was too young for menopause, and I had a partial hysterectomy a few years earlier. She told me it was perimenopause. As she explained, that could last for years before full menopause began. For me , it was 10 years and then full menopause a year and 9 months or so. I was so glad to have an explanation ! I wasn't a crazy person after all..lol.

I found out that a lack of or low vitamin D also causes sweating. I was beginning to sweat often and never had any problems before until I quit taking vitamin D to help bring up my blood platelets. Once I began taking the vitamin D again the sweating disappeared but platelets came down.
:(

I have loved hot weather my entire life. My motto was it could never be too hot!
I am 78 now and the past three years heat and high humidity can cause me to feel panicked. I have to get to cooler areas. I perspire enough that my hair is dripping wet.

I also seem to have a lower tolerance to cold weather as well. I live in MInnesota and when it gets to around zero I find I have to take breaks from snowblowing after about 15 minutes to come inside and warm up. I use good cold weather gear glove warmers etc.

I have assumed that it might be age related.

Could it be a side effect to any medication that you are on ?

Yessss!!!!
