Social bonds and ritual may explain why sauna use is linked to better wellbeing in the UK

A three-study programme involving nearly 1,900 sauna users in the United Kingdom examined whether social identity and the experience of shared ritual help account for the wellbeing benefits people report from sauna use. Across longitudinal and cross-sectional designs, stronger identification with sauna communities and perceiving sauna as a ritual were both associated with higher emotional and self-reported physical wellbeing.

What the study found

The research drew on the Social Cure framework — the idea that belonging to meaningful social groups can itself be health-protective — and applied it to sauna culture for the first time in a UK context. Three separate studies were conducted, combining longitudinal tracking with a cross-sectional survey to build a layered picture of how sauna participation relates to wellbeing.

The two longitudinal studies (Studies 1 and 3) found that participants' emotional wellbeing tended to increase over the observation period, though the observational design means factors other than sauna use could account for this change. The cross-sectional study (Study 2) found that people who reported a stronger sense of identity as sauna users also reported greater improvements in both emotional and physical wellbeing, again as a self-assessed measure.

Study 3 added a further layer by examining what strengthens sauna identity in the first place. Viewing sauna sessions as rituals — structured, meaningful, repeated practices — and experiencing a sense of emotional synchrony with others present were both positively associated with stronger sauna identity, which in turn was linked to wellbeing outcomes.

The authors are careful to frame these as associations rather than causal effects. They suggest the social and ritual dimensions of sauna may be active ingredients in its appeal, not merely incidental features, but the study design does not permit conclusions about whether sauna use itself drives the observed wellbeing changes.

Limits worth knowing

All wellbeing measures were self-reported, introducing the possibility of recall bias and social desirability effects. The sample was drawn from UK sauna users, a group that may differ systematically from the general population in health behaviours, socioeconomic status, and baseline wellbeing, limiting generalisability. The longitudinal studies did not include a non-sauna control group, so it is not possible to rule out natural variation in wellbeing over time. Funding sources and potential conflicts of interest are not described in the available abstract. The studies did not measure physiological outcomes, frequency or type of sauna use, or distinguish between different sauna formats.
