The Case for Sharing Your Sauna: Benefits Beyond Heat
Almost everything written about saunas focuses on the same handful of numbers: how hot, how long, and how many times a week. And fair enough, these all matter in terms of the underlying mechanisms involved in how saunas work, with the main goal being an increase in core body temperature and the release of heat shock proteins.
But new research out of the UK points to something we often forget while we’re busy optimizing our heat exposure: a meaningful share of the benefits of sauna therapy comes not from the heat, but from who’s on the bench next to you.
It’s an easy thing to overlook, especially in the United States, where home saunas have become a private, solo ritual where we can finally have a quiet 20 minutes to ourselves before the day starts or after it ends. That’s valuable, but it’s also leaving something on the table.
What the Latest Research Found
A team led by Dr. Martha Newson (University of Greenwich and the University of Oxford’s Centre for the Study of Social Cohesion) and Rachael McGrath (The London Interdisciplinary School) published three linked studies of UK sauna users in the journal Social Science & Medicine. Rather than measuring heart rate or blood pressure, they looked at the social side of sauna use: the connection and sense of belonging that build up around shared heat exposure. (1)
The main takeaway from the study was that shared sauna sessions are associated with higher wellbeing rather than through heat exposure alone. People who felt part of a sauna community (whether with family or friends) reported better physical and mental health outcomes than the heat dose by itself would predict.
A couple of nuances worth covering:
- Frequency mattered differently for body and mind. More frequent (weekly) use tracked with higher physical wellbeing, while monthly use was linked to higher mental wellbeing. The pattern suggests these may not be the same mechanism.
- The framing is preventative, not clinical. The researchers situated their findings against the UK’s well-documented loneliness problem (a rampant problem we have here in the states as well), noting that weak social ties carry health risks and proposed sauna culture as something worth exploring as a preventative lifestyle practice, not a treatment.
The theoretical backbone here is the social connection model which is a body of psychology research showing that belonging to a meaningful social group is good for your health. What this team did was apply that lens to the sauna bench and find that it fits.
Why This Shouldn’t Surprise Us
Strip away the novelty and the finding is almost obvious in hindsight. Social connection is one of the strongest predictors of long-term health we have, it shows up in the longevity literature again and again, often rivaling diet and exercise in effect. If you’ve ever heard of or read the book The Blue Zones, you know that the cultures with the most amount of centenarians (people living over 100 years) share a single common denominator which is strong social ties and the meaning that comes from that.
So if a practice combines a physiological stimulus (heat) with a reliable, repeated, social ritual, we shouldn’t be shocked that the two together outperform either alone.
There’s also a nervous system angle. Ritual, doing the same thing, in the same place, with the same people, on a predictable rhythm, is a quietly powerful down-regulator. It signals safety. Pair that with the parasympathetic shift (our rest and digest nervous system state) that follows heat exposure and a cooldown, and you have a setting that lowers your body’s stress baseline (2). The company on your sauna bench isn’t a distraction from the benefit, it’s an added benefit.
Look across cultures and the pattern is everywhere. In Finland, Japan, Russia, Turkey, and many Indigenous traditions, the hot room has always been a social ritual as much as a health practice. The 2026 research is really just catching modern science up to something these cultures have known for millenia.
What This Means for Home Sauna Owners (Especially Infrared)
Privacy and personal convenience are often the selling points for home saunas, but the good news is that the social dimension isn’t a feature you have to buy, it’s a choice you make about how you use the sauna. And a home infrared sauna is actually well suited to it.
The lower air temperatures of far infrared saunas (typically around 120–140°F at the body, versus 170–200°F in a traditional sauna) make for a more conversational environment. It’s easier to sit and actually talk for 20 or 30 minutes when you’re not being blasted by really hot air. Infrared heat is gentler and more tolerable, which means the session can be as much about your company as the sweat. This makes it a genuinely good setting for the shared ritual this social sauna research points to. You just need a sauna with room for more than one.
Practical Social Tips
In order to get more of the social dimension of sauna therapy, the practical takeaway is simple: stop treating your sauna as a solo appointment by default.
- Invite someone in. The most direct lever. Inviting a partner, family member, or friend turns a solo session into a shared one and adds to the belonging ingredient the research points to.
- Make it a ritual, not a task. Same evening, same wind-down, same people. Predictability is the point. A regular shared evening session beats a sporadic solo session in this regard.
- Protect it as social time. Leave the phone or tablet outside. The value isn’t just co-location, its actual conversation and presence, which is the part screens take away.
- Build the habit around your space. This is one of the biggest advantages of owning a sauna at home. Iit removes every barrier between you and consistency. No booking, no drive, no gym or health center membership. The thing most likely to turn an occasional nice idea into a genuine weekly shared ritual is simply having the sauna a few steps away.
The Takeaway
Heat therapy is real and the hundreds of human studies to prove it are genuinely impressive. But the 2026 study is a useful addition to how most of us have come to use saunas. The bench, it turns out, may be as important as the heat.
If you own a home sauna, you already have the hardest part solved: a wellness space that’s available whenever you want it. The upgrade this research suggests doesn’t cost anything. It’s just a second or third person, a regular time, and the willingness to treat that warm room as a place to connect, not only a place to sweat.
If you’re considering buying a new home infrared sauna, it’s worth choosing with the social dimension in mind. Our 2-person or 3-person sizes give you the room to share the bench with others.
