Thought. I have always run warm. I do feel the cold, but not as much as most people. I hate (detest?) overheated department stores. This got worse with the onset of perimenopause, & I was unable to wear jumpers for years, because I couldn’t get them off quickly enough during hot flushes, which threatened spontaneous combustion. This settled somewhat after finally going on HRT.
I’ve noticed a change since going on ADHD meds. I now wear winter pjs on a “cool” summers night, & a nightie on warmer ones & am more likely to don a jacket of an evening.
