5 out of 5 ! The bite-size nature of the video instructions made it really digestible and easy to pick up in manageable learning modules. Good balance of the scientific background and research to underpin the benefits and practical applications. I would recommend this course to anyone interested in improving their physical and mental health through the most natural and readily accessible heat and cold therapy. This could be genuinely life-changing for those willing to commit the three weeks needed to create new habits that lead to the Thermalist lifestyle. Brilliant!
Such a pleasure taking this course!! Just brilliant presented and easy to follow and do. I rate it 5 out of 5! I love the bite-size library of content. I could do it in my own pace, and rewatch, which fit my worklife. Dr. Soeberg really made a well-balanced course of both theory and practice - you know why this is good and then how to do it. The thermalist cure is really a lifechanging approach! Eye opening course. Thanks to Dr. Susanna Soeberg for everything you do.
