In November 2017 researchers from the UK, Finland and Austria published the results of their study to assess the association between sauna usage and risk of hypertension. A total of 1,621 men, aged 42 to 60 years, with no history of hypertension were included in the study. Information on sauna usage was collected via questionnaire. The individuals were divided into three groups according to the number of sauna sessions undertaken per week; namely 1, 2-3, 4-7 sessions. During an average follow-up period of 25 years 251 diagnoses were made. Results showed that regular sauna usage was associated with a reduced risk of hypertension.
