Primary

MeasureTime frame

Secondary

MeasureTime frame
• Hamilton Rating Scale for Depression-17 (total score): Difference between groups 4 weeks after end of treatment (follow up). • Hamilton Rating Scale for Depression-17 sub scales: Difference between groups after 4 treatments and 4 weeks after end of treatment (follow up). • Heart Rate Variability (parameter): Total Heart Rate Variability, Low Frequency, High Frequency) and heart rate during sleep (21:00 - 04:00 h) after 4 treatments and 4 weeks after end of treatment (follow up) compared to the control group and correlation with Hamilton Rating Scale for Depression-17 (total score) and subscales. • Adverse effects. • Global judgement of efficacy and tolerability on a 5-item scale by the participants. • Core body temperature measured by an ear thermometer before and after the bath and after the resting time.
