Cold and Heat Through Menopause: The Science, and How to Practise It Well
The sauna study that finally included women and what it found, the honest truth about the cold water data, and how to practise both when your body has changed the rules.
Menopause is one of the most under-served areas in the whole of health science, and it is under-served in a specific way. There is no shortage of attention on the symptoms. There is a serious shortage of precise, physiologically grounded guidance on what to actually do, built for a body that is changing rather than a body assumed to be stable.
Cold and heat are two of the most useful and most underused tools in this transition. In this piece I want to do three things properly: explain what is actually happening to your metabolism and thermoregulation as oestrogen declines, walk through the real evidence for cold and heat in this stage, including its limits, and then translate all of it into a practice you can run intelligently as your body moves through the transition. I am going to take my time, because generic advice is exactly what has failed women here, and I am not going to add to it.
In this piece:
What actually changes in your metabolism and thermoregulation as oestrogen falls
Why the cardiovascular system loses a layer of protection, and what that means practically
The Finnish cohorts on sauna and mortality, including the one that included women, with the numbers
What the cold water survey genuinely shows, and where its limits are
Why heat is the priority tool here, and how to use it well
How to use cold safely when thermoregulation is already unstable
How to keep adjusting across a transition that keeps moving
