Blood pressure . Physiologically when you take a bath if you are submerged you experience the mammalian diving reflex and your blood pressure elevates however the hotter the water the more your blood vessels will want to dilate and keep your core cool. I would stay hydrated and try to shower instead and see MD to screen your blood pressure, set of labs please. .
