Thermalist® Women’s Retreat in Sweden
This is a unique opportunity to experience the Thermalist Method® with Dr. Susanna Søberg — and live as a Thermalist for four days. A small, women-only retreat with limited spots available.
Halmstad, Sweden • 24–27 April 2026
A 4-day science-based retreat for women led by Dr. Susanna Søberg
Cold • Heat • Hormones • Metabolism • Menopause • Nervous System Reset
The retreat
It’s designed for women in all life stages — especially those navigating hormonal shifts in their 30s, 40s, 50s and beyond.
Whether you're curious about peri-menopause, actively moving through menopause, or supporting someone who is, this retreat brings clarity, science, and practical lifestyle tools you can use for the rest of your life.
Women’s Hormones /
Peri-Menopause & Menopause Focus
During Dr. Søbergs Women’s Health Masterclasses on the Retreat, you’ll learn e.g.:
How to recognise early signs of peri-menopause (even 5–10 years before menopause)
What symptoms are not “just normal” — and what your body is really trying to signal
What to measure (blood markers, temperature patterns, cycle changes, metabolism shifts)
How cold & heat exposure affect estrogen, stress hormones, metabolism & sleep
What to do daily, weekly and monthly to feel better — without guessing or following trends
How to support energy, muscle, mood, sleep, fat storage, and inflammation naturally
This is evidence-based hormonal education.

WHAT OTHERS ARE SAYING
The work you are doing is very important. As an interventional pain management physician I am always looking for non invasive ways for patients to improve their health and pain.
Dr. Søberg you have helped me so much with my new cold water plunge routine. I look forward to learning more about the optimum time to increase my metabolism, eliminating weak mitochondria and more. Thank you!
I am fascinated by your knowledge of metabolism and all things hot and cold. I am on my own wellness journey that includes nutrition, cold plunge and infrared heat.
Thank you from Australia! I am excited to learn more and love the work you are doing. I have started cold plunging for the past 10 weeks and noticing benefits but also dealing with problems such as reynauds and chilblains. I hope I can learn more to help me on my journey
Thank you for making the science of beath, cold and heat so accessible. Looking forward to becoming your first instructor from South Africa.
My husband and I love your work. We've done Bikram since 2008 and now I'm teaching it. Your work in cold is of great interest and you've inspired us to put in a cold plunge. Thank you!
I find your work really interesting. It supports my work as a cold water therapy coach, breathing coach and menopause wellbeing practitioner. I'm interested in your Thermalist Instructor Course as well, so want to keep up to date with your work. Thank you
The principles that you endorse have proven very effective for our family's health and physical performance
I first learned of you from Peter Attila's Podcast. I was so intrigued by your work. Thank you!
Thank you so much for all of this incredible information you put on. From the first time that I erased myself in an ice bath I went in to total shock and had no idea about the physiological effects that were occuring. After reading your first book and listening to many of your podcasts I now use this information to help men tackle mental health issues in my Men's group events.
Love your story, heard you on many different podcasts and you got me talking cold showers and talking about it to many of my patients. Keep up the great work!
I love how you really care about people's health
Glad to support your work as it has already made mine and my families life better!
I run a sauna and cold plunge business in New Zealand and love your work. Thank you for sharing this knowledge in a digestible way.
I'm sincerely hoping your information on the thermal therapy will help my wellness journey post pulmonary embolism
I'm excited to learn more about the cold water immersion and breath work. Looking forward to learning more about the instructor program.
You have changed my life and I'm hoping I can change others using your information. Thank you
Thank you for sharing such vital data in actionable ways!
I love your thoroughly evidenced approach while communicating effectively without scientific jargon. Thank you
