Hi Mel...
When you're sensitive to heat, it's a shocker, hey. It can change so much. Can change your inner dialogue, shift your focus away from what you want to be focusing on, disrupt your sense of peace and breathing patterns, upset certain natural much needed processes like those that come with restorative sleep and the list goes on. I joke how it's like I become possessed when the days reach a certain temperature and especially level of humidity. I become quite angry if I can't regulate my body temperature.
Being one of those mind/body/spirit kind of gals, one area of research I've come to love is quantum physics which is largely about the behaviour of energy. Given that we're energetic creatures in a number of ways, we partly work in relation to external energy input. Drinking plenty of hydro power (water), eating foods that rely on nuclear energy (from the earth) to grow, getting enough of the right amount of solar power (sun) for vitamin D and stuff and generating kinetic energy from exercise are just some of the many ways in which we gain and maintain energy. I'd never considered thermal energy until you raised this issue. I greatly appreciate you leading me to become more conscious. I suppose it's fair to wonder 'How do we manage too much thermal energy within the body, to the point where it's uncomfortable and disruptive?'. With the body having to work hard in managing too much heat for its own good, it becomes a matter of reducing the amount of work it has to do, therefor reducing the amount of activity or hyperactivity it experiences (that can be felt as anxiety). stell_a178 mentions a number of really good ways I can personally relate well to. Ice cold water and air condidtioners are my best friends on some days.
Might sound a bit strange but something that I've found which works well at times involves me asking my body 'What do you want me to do?'. I hope I lead you to smile when I tell you one of the responses that came to mind one day was 'Pant like a dog' 😅. If you've got a good imagination, you'll be able to picture some crazy woman with her tongue hanging out (not something I do in public). Technically, this is one of the key ways in which animals release heat. So, it's not just about cooling things down, it's also about releasing some of the thermal energy. Another way in which I manage involves researching what the temperatures are going to be for the week. When I see days that I know are going to test me, I plan ahead for those days. Btw, one of the things I get sick of people saying is 'You're having hot flushes'. As a 53yo gal who has a slightly higher natural core body temperature than what's average, on seriously hot days it doesn't take much to increase it to the point where I struggle to tolerate an extra degree or 2 (regarding my core temperature).
