Are you taking any medications ? I know that certain drugs can cause heat intolerance.
Do you drink a lot of caffeine ? If so, you may want to consider cutting down and see if that helps your symptoms. If not, then maybe you want to get your thyroid level checked again.... just in case.
Good luck !
