I'm almost 54 and menopaused for over 2 years now and I'm mostly always too hot. Today we were riding. It was very windy (points at 45km/h SW) and started off at 15c. I endured my very thin windbreaker for about 10km, if not less. Then I removed it and was just short sleeved jersey. I think I was the only cyclist without a jacket on for at least most of the ride. lol We only did a 50km ride and I felt sweat running down my back. The weirdest thing is sleep during the night ... blankets fly away. Comes 6am, I'm so cold I'd need an extra blanket. So if I nap during the day I'm always chilly.
But doing gym, I'm like you...pee feels so hot vs before.
So yes, it seems my body temperature is higher and I flush (heat) more easily as I get older. And it is so much harder too to lose the weight, or at least manage what I have. grrr.
