I would love to know and confirm the difference between hormone response in women and men. And would love to know for sure if women should be using specific cycle-synced protocols or if that is not necessary for maximum benefits. Thank you so much for the work you do!
What I appreciate here is the distinction between what’s genuinely proven, Like cold and heat’s measurable effects on stress and energy, and the tower of claims that are still speculation. It’s a reminder that being ‘science‑backed’ isn’t about citing a paper, it’s about knowing where the evidence stops and being willing to test the gap
I would love to hear your take on Cryo chambers. Knowing that a bottle of wine only gets cold inside out quickly if it is an ice water because of the conductivity, I am extremely skeptical Cryo chamber can have any effect at all. All these fancy spas are charging an arm and a leg for a few minutes. Great way to make money obviously!
I do at least 11mins in cold and 57 minutes in hot every week. I'm a male in my 50s my wife is 20 years younger than me and we have young children, so unsurpisingly my main reason/interest is health/longevity (I do lots of other longevity type work not just hot/cold). I understand there are no gurantees in longevity space, but my current understanding is that it is possible your 11/57 weekly protocol will increase my life span. So that's why I do it every week 🙏🏻 ps anyone reading this wants me to join any type of research/study I'm happy to share my data (the data on my whoop is shareable).
This is such an important distinction for the thermal bathing field.
The problem is not enthusiasm for sauna, cold, or contrast. The problem is when early science, mechanisms, or limited studies get translated into broad public claims that sound more proven than they are.
For operators, this becomes more than a science issue. It affects consumer trust, informed participation, staff scripts, marketing language, and long-term credibility.
Good risk architecture helps protect the conditions that allow people to trust the practice.
I would like to know how much of an effect heat and cold, sauna and cold plunge can have on the body and inflammation, specifically inflammatory autoimmune diseases. I have had inflammation from sports injuries/surgery for a long time but after the first 2 covid vaccines my body exploded with psoriatic arthritis. Prior to that I was active, felt much better though had lasting damage, in shape and in the gym 5 days a week. At 36, five years ago this crashed my world and pain increases every week despite biological meds. I look for anything to help. I doubt I’ll ever live normally again and the road is bleak. I have a sauna and cold plunge but often feel too bad, in pain and depressed to even use them as my life has become pure suffering. Should I pursue these heat / cold treatments with more effort or am I wasting my time? I doubt there’s any hope for slowing the disease or even relief. Thanks.
Personally I’ve had the same diagnosis and dilemma! I informed my consultant that I was going to sauna when possible around the fatigue/pain.
He fully supported me! It’s now the only accessible modality I have to improve my health and wellbeing. I’m going to invest what I have into learning more from Dr Soeberg . Just finished a call from the rhuematology team who are undertaking clinical research and I notified them about my own findings and if they can include it in the report…
Having research validate the impact of cold/hot 11/57 on neurological degeneration would be interesting. As both my parents and my spouses’ parents are currently dealing with progressive dementia as are many of my older adult friends. I have been a faithful 11/57 user over the past 2 years and hopeful this is having an impact and reducing my neurodegenerative danger in the not to distant future (61/male). Very much appreciate your work Susanna !!
I approached you at the first UK Sauna Summit asking about research / impact of thermal bathing on menopausal women. I believe there is none currently but did you know of anyone working on this?
I'd like more data on the response to different temperatures and times of water for immersion. If 11 minutes is good, what happens to someone who does 5-7 days a week for a total of 20-30 minutes. What happens with shorter times in colder water. What is the upper temperature to derive optimum benefits and what is the lower end. I'd also like to see data on the impact of heat immersion on Testosterone in males.
Should I do hot, cold, hot, cold or just hot cold? And, sorry!, what if someone doesn’t feel well - overly cold, shaky, core temp drops, faint? Thank you

and also being able to spot the quality of the study.

There aren't really any studies are there on cryo?

I would love more information on the ideal temperature of a cold plunge for men vs. women.
How long for and to what extent dopamine levels are raised. I assume it's possible to measure dopamine in the blood?
Love what you say about lack of proven research. Everyone claiming all these benefits.

It's good to be plain speaking about this. The claims for cold got really out of hand. I believe the studies into heat are more numerous.
I would love to know if it truly matters to your workout gains if you have a dip afterwards in the sea.
