How do I approach my boss about my menopause symptoms?

My boss is a younger man, in his mid-30s, with a wife around his same age. It's clear he hasn't yet had much by way of close personal contact with menopausal women (or knowingly had that contact, I mean). I say this because when he and I go on calls/drive to meetings together, he BLASTS the heat. Every time. I ask him to turn it down, but at that point I'm already sweaty, physically uncomfortable, and irritated. If he knew how this was impacting me as a woman going through menopause, I think he would behave differently. But how do I bring this up??
