Sauna culture is becoming the hottest wellbeing trend.

You probably never expected your doctor to recommend sitting in a wooden room wearing a towel and quietly sweating beside strangers, yet science is edging surprisingly close to exactly that. 

Researchers from University of Greenwich, University of Oxford, University of Kent, The London Interdisciplinary School and British Sauna Society have been studying whether communal sauna bathing can reduce loneliness and improve wellbeing. Their findings suggest that regular sauna visits do more than warm your toes. They may also help you feel more connected to other humans, which is increasingly important in a world where many people know their food delivery driver better than their neighbours.  

The researchers analysed three separate studies involving more than 1,900 participants across the UK. One study followed 32 London sauna users before and after traditional aufguss rituals, where steam and scented heat are dramatically circulated around the sauna by a towel waving sauna master. Another survey collected 1,798 responses about physical health, mental wellbeing and frequency of sauna use. A third study involving 74 people explored what scientists call “identity fusion”, which is essentially the feeling that you belong strongly to a group. 

The people who felt the greatest sense of connection with their sauna community reported the best emotional outcomes. Weekly sauna sessions were linked to improved physical health, while both monthly and weekly visits were associated with better mental wellbeing.  

Researchers explain that people are not simply turning up for the heat but for the sense of community that grows through shared rituals. That idea is gaining traction because loneliness is now treated as a serious public health issue. They confirmed that social and psychological interventions can meaningfully reduce loneliness. There is now strong evidence that repeated heat exposure is beneficial for human health, particularly cardiovascular health.  

Of course, none of this means you should immediately move into a sauna full time and emerge only for snacks and WiFi. Experts still say moderation matters, especially if you have heart conditions or other medical concerns. Yet the growing research does suggest you might benefit from swapping one lonely evening scrolling your phone for a social sauna session with actual humans. The science increasingly points to the idea that wellbeing is not only about green juice, fitness trackers and expensive supplements. Sometimes it is about sitting in a very hot room, chatting nonsense with strangers while collectively resembling baked potatoes.
