ABSTRACT
OBJECTIVES:
Finnish sauna bathing is associated with a reduced risk of adverse health outcomes. The acute physiological responses elicited by Finnish sauna bathing that could explain this association remain understudied. This study characterized the acute effect of Finnish sauna bathing on circulating markers of inflammation in healthy middle-aged and older adults.DESIGN:
With the use of a crossover study design, 20 healthy middle-aged and older adults (9 men/11 women, 66⯱â¯6 years old) performed 3 interventions in random order 1) 1â¯xâ¯10â¯min of Finnish sauna bathing (80⯰C, 20 % humidity); 2) 2â¯xâ¯10â¯min of Finnish sauna bathing; 3) a time-control period during which participants sat outside of the sauna for 10â¯min. MAINOUTCOMES:
Venous blood samples were obtained before (≤15â¯min) and after (â¼65â¯min) each intervention to determine circulating concentrations of interleukin 6 (IL-6), interleukin 1 receptor antagonist (IL-1RA), and C-reactive protein (CRP).RESULTS:
IL-6 increased in response to 2â¯xâ¯10â¯min of sauna bathing (+0.92â¯pg/mL [+0.16, +1.68], Pâ¯=â¯0.02), but not following the 1 x 10â¯min session (+0.17 pg/mL [-0.13, +0.47], Pâ¯=â¯0.26). IL1-RA increased during the 1 x 10â¯min (+51.27 pg/mL [+20.89, +81.65], Pâ¯<â¯0.01) and 2 x 10â¯min (+30.78 pg/mL [+3.44, +58.12], Pâ¯=â¯0.03) sessions. CRP did not change in response to either sauna session (Pâ¯=â¯0.34).CONCLUSION:
These results demonstrate that typical Finnish sauna bathing sessions acutely increase IL-6 and IL1-RA in healthy middle-aged and older adults.Palavras-chave
