Finnish sauna bathing, an activity that promotes relaxation and wellbeing, has become increasingly popular worldwide. Regular sauna bathing is associated with reduced risks of fatal cardiovascular diseases and allcause mortality (Laukkanen, Khan, Zaccardi, & Laukkanen, 2015), and acts as a protective lifestyle factor against common memory diseases (e.g., dementia and Alzheimer’s disease) (Laukkanen, Kunutsor, Kauhanen, & Laukkanen, 2017). Sauna bathing has also been used as a thermal therapy to treat pain, aches, and other symptoms of rheumatic disease (Isomäki, 1988; Nurmikko & Hietaharju, 1992). The usual sauna visit consists of short stays (5–20 min) in dry air (relative humidity (rh) of 10–20%) at a relatively high temperature (air temperature (Ta) 80–100 °C), which induces short-term mild to severe whole-body hyperthermia (Leppäluoto, Tuominen, Väänänen, Karpakka, & Vuor, 1986). Hyperthermia is a physiological stress (Moran, Shitzer, & Pandolf, 1998), under such thermal conditions, the heat-stressed brain operates at lower levels of blood and energy supply, resulting in impairments in brain neural networks (Nybo, 2010; Rasmussen, Stie, Nybo, & Nielsen, 2004) and metabolism (Nybo, Møller, Volianitis, Nielsen, & Secher, 2002) which lead to suppression of cognitive function (Racinais, Gaoua, & Grantham, 2008) and motor inhibition (Brazaitis et al., 2015; Nybo & Nielsen, 2001). However, little is known about the functional residual consequences of recovering body temperatures from moderate whole-body hyperthermia in a thermoneutral environment on the effectiveness of cognition, motor performance and stress hormones level. This knowledge gap is surprising given that in the heat-stressed brain, the water, hormonal and neurotransmitter balances are disturbed and brain morphology is altered (Kiyatkin, 2005, 2010), and cognitive modulation (dysfunction or arousal) may persist into the recovery period after removal from the sauna heat or heat per se. Also disturbance in water and ...
