Abstract

Background and aim

Sauna-type bathing has increased worldwide, and it has been related to both harmful and beneficial effects. There are few studies of bathing in sauna in very old age.

Methods

The series consists of 524 mostly home-living survivors of the Helsinki Businessmen Study (HBS, mean age 86 years, range 80–95), who in 2015 responded to a questionnaire survey about lifestyle (including sauna bathing), prevalent diseases, and health-related quality of life (HRQoL, RAND-36).

Results

Of the men 57.6% (n = 302) reported all-year round and 17.6% (n = 92) part-year sauna bathing. Sauna was currently used mostly once a week, but 10% bathed more than twice a week. Median time in the hot room was 15 min at 80 °C. Among 45.7% of the men, the habit had decreased with ageing, and 130 (24.8%) did not attend sauna. However, 92.2% of the latter had discontinued an earlier habit, respective proportions 20.7% and 75.0% among all-year and part-year users. Overall, reasons for decreased sauna bathing were nonspecific or related to mobility problems or diverse health reasons (n = 63). The most frequent motivations for sauna were relaxation and hygienic reasons. Of the RAND-36 domains physical function, vitality, social functioning, and general health were significantly better among sauna users than non-users. These differences partly remained after adjusting for prevalent diseases and mobility-disability.

Conclusions

Regular sauna bathing was common among octogenarian men and was associated with better HRQoL. However, reverse causality must be taken into account in this cross-sectional study. The bathing habit seemed to be prudent and had decreased in almost half of the cohort.
