“…Though there is no active function of skeletal muscles during sauna baths, it has been reported that the response produced by an ordinary sauna bath corresponds to that produced by moderate or high intensity PA, such as walking. 44 Sauna bathing appears to work comparably to PA by systemic blood pressure reduction; 41 reduction in oxidative stress 45,46 and inflammation; 42,47 improvement in endothelial function; [48][49][50] positive alteration in levels of circulating lipids; 51,52 improvement in glucose metabolism; 53 improved arterial stiffness, arterial compliance, and intima media thickness; 36,45,[54][55][56] and improvement in the cardiorespiratory system 57 as well as CV function 31,33,58 . Some early evidence indicates that sauna bathing improves cardiac autonomic nervous system balance, leading to an increase in vagal tone and a decrease in sympathetic tone, with positive modulations in heart rate variability during the recovery…”
