Effects of the Sauna on Diffusing Capacity, Pulmonary Function and Cardiac Output in Healthy Subjects

Abstract: The present study examined possible short-term effects of the heat stress during sauna bathing on gas exchange, especially in correlation with changes in cardiac output. The results obtained are as follows: (1) The heat stress of sauna bathing caused a slight but not significant increase in diffusion capacity (p = 0.239) and no change in other pulmonary function parameters. (2) Cardiac output and cardiac index increased slightly but not significantly (p = 0.2455 and p = 0.2719). We conclude that heat stress in… Show more

“…Sauna bathing, a well-known form of whole-body heating, is well-tolerated by most healthy individuals, both young and old between childhood and old age [10,16,18]. Repeated sauna bathing influences endogenous regulatory mechanisms, mainly acute and transient cardiovascular and hormonal changes, by maintaining a balance between fluid composition and the distribution of circulating blood [1].…”

“…Males showed significantly greater MEP enhancement across stimulus intensities than female subjects, The increase in HR with heat stress in the present study was consistent with previous findings from our lab using the same heating protocol (92). The increase in HR is a compensatory response to avoid a large drop in mean arterial blood pressure, so that the cardiac output can be relatively stable even with reduced stroke volume (105). HR for subjects in both experiments increased to roughly 65% of age-predicted maximum HR (220age), which is considered moderate in exercise (71).…”
