Sauna Benefits is an independent website that explains what the research says about saunas, heat therapy and cold water for people in the UK. It is written by one editor under a pen name, sells nothing, carries no adverts and takes no money or free sessions from sauna makers or venues.

Why does this site exist?
Saunas have arrived in Britain. A few years ago there were only a few dozen Finnish-style public saunas in the country; now there are hundreds, from harbour-side huts to rooftop clubs, and more people are buying one for the garden. With them come big claims: that a sauna will detox you, melt fat, cure your cold or add years to your life.
Some of those claims rest on large, long-running studies. Others rest on nothing at all. Most of what you find online is written by companies selling saunas, blankets or memberships.
We wanted one place that answers the practical questions plainly: what heat and cold really do, how strong the evidence is, how to use them, and who should be careful.
Who writes it?
The editor writes under the pen name Kit Ellery. Kit is not a doctor or physiologist, and the site does not give personal medical advice. We are looking for a qualified reviewer for the health pages. Until then, no page claims to be medically reviewed.
How is the site paid for?
At the moment it isn’t: the editor covers the small running costs. If that changes, for example through clearly labelled affiliate links, we will say so on this page and on every page that carries them, and it will never change an evidence grade.
What will we never do?
- Accept payment, free sessions or “sponsored” content from sauna makers, retailers or venues.
- Rank or recommend a product or venue because someone asked or paid.
- Present an animal study, a manufacturer’s claim or a customer review as evidence that something works.
How do we decide what is true?
By reading the human studies and reviews, grading each claim on a published scale and linking every claim to its source so you can check it. Our editorial policy explains the process, including how we use AI tools and how we correct mistakes.
