- Brief Summary
Sauna bathing is a popular, low-cost, and easily accessible type of whole-body thermotherapy that has been used for social, religious, health, and hygienic reasons for thousands of years. There is strong evidence to support the various physiological and psychological benefits of sauna bathing. The positive effects of regular sauna use have been explained by a number of mechanisms of action, including increased cardiac output, reduced peripheral vascular resistance and other physiological changes in cardiovascular parameters such as decreased systolic and/or diastolic blood pressure. Additionally, the psychological impact of sauna bathing may occur due to a combination of factors that include the release of endorphins, relaxation, placebo effects, and psychological and social interactions that likely occur around frequent sauna activity. Taken together, it is possible that acute and regular sauna bathing may impact sleep quality.

- Primary Outcome Measures
Name Time Method Objective Sleep - Time in bed 5 weeks Total time spent in bed during the night assessed by sleep radar
Objective Sleep - Sleep-onset latency 5 weeks The time it takes from when the participant intends to go to sleep and actually starts to sleep assessed by sleep radar
Objective Sleep - Light sleep 5 weeks Total amount of time in light sleep assessed by sleep radar
Objective Sleep - Deep sleep 5 weeks Total amount of time in deep sleep assessed by sleep radar
Objective Sleep - Total sleep time 5 weeks Total sleep time obtained from sleep onset to time at wake-up assessed by sleep radar
Objective Sleep - REM sleep 5 weeks Total amount of time in REM sleep assessed by sleep radar

- Secondary Outcome Measures
Name Time Method Subjective Sleep Quality assessed by Karolinska Sleep Diary 5 weeks Stress level assessed by VAS scale 5 weeks VAS scale is a 11-item self-report measure for stress. Answers range from 0 (no stress) to 10 (worst stress).
Positive and Negative Affect Schedule (PANAS) baseline, after 1,3,6,9 sauna bathing, after 5 weeks The PANAS is a 20-item self-report measure for positive and negative affect.
Mood baseline, after 1,3,6,9 sauna bathing, after 5 weeks Mood Adjective Check List (UMACL) will be used to assess mood (Mathews, Chamberlain \& Jones, 1990, adapted to Polish by Ewa Goryńska, 2005). UMACL measures mood in three dimensions of the core affect: Tense Arousal (minimum value: 9, maximum value: 36), Energetic Arousal (minimum value: 10, maximum value: 40), and Hedonic Tone (minimum value: 10, maximum value: 40), with higher scores representing higher levels of the mood dimensions.
