Hi. I’m a 49 (for 3 more weeks) year-old woman, not yet going through menopause, as far as I can tell. I have been enjoying Bikram for four years, although I never learned to love the heat and frequently got head aches after class. Recently, I have started to feel extremely nauseous during class and find myself sitting out half the poses. Last class, the teacher had to bribe me with a towel soaked in her cold water and put on my forehead, or I would have walked out. I barely had to sit down, even in my first class, before about a month ago. I keep going, but it’s beginning to feel like a waste of a precious hour and a half, when I can comfortably do other yogas and swim and bike without any discomfort. I have adjusted when I eat before class; I always eat lots of potassium and a reasonable amount of salt; and plenty of fluids. I hope you don’t mind my joining this thread, but I suspect there may be a link between heat tolerance and perimenopause, and I would love some insight.
