Sauna and Hormones | How Sauna Affects Stress, Growth Hormone, and Testosterone
Sauna regulates cortisol, increases growth hormone levels, boosts endorphin production, and positively influences hormonal balance.

Introduction
Hormones are the control center of our body – they affect mood, energy, sleep, and muscle growth. When they are in balance, we feel strong and full of vitality. Sauna can be one of the tools to support this balance. It’s not just about relaxation, but also a subtle form of biohacking that changes our hormonal response.
1. Clinical studies and evidence
Cortisol
Finnish studies have shown that in people who regularly visit saunas, cortisol (the stress hormone) levels significantly decrease after adaptation.

A study (Greiwe JS, 1998) confirmed that exposure to high temperatures can temporarily double growth hormone levels.

1. Reduction of cortisol – regular sauna use helps the body cope with stress and promotes relaxation.
2. Stimulation of growth hormone – heat activates processes of regeneration, muscle growth, and fat burning.
3. Release of endorphins and serotonin – sauna improves mood and provides a feeling of happiness.
3. Patient experiences and expert videos
Health benefits of sauna and how it increases growth hormone - Dr. Gray
Since I recently started using the sauna, I have realized its great health benefits. I did some research on sauna and was surprised at how beneficial it can be. Not only is it a great way to sweat, but it can even stimulate growth hormone.
I Tried a Sauna Routine by Andrew Huberman (19x Growth Hormone)
Last year, Dr. Andrew Huberman recorded a podcast in which he mentioned a study showing that certain sauna protocols can increase growth hormone levels 16-fold.
4. Risks and limitations
Too frequent or extreme sauna use may, on the contrary, increase the stress response.
Sauna’s effects on testosterone are still debated – levels may drop temporarily, but in the long term, sauna supports overall health, which stabilizes testosterone.
Not suitable for people with hormonal disorders without consulting a doctor.

6. Summary (scientific)
Sauna significantly affects hormonal balance – it lowers the stress hormone cortisol, supports growth hormone production, and increases endorphin levels.
Summary in human language
After a sauna session, you feel calmer, happier, and more energized – and that’s no coincidence. Sauna directly influences your hormones. It reduces stress, supports regeneration, and provides a natural dose of “happiness hormones.” It’s a simple, natural way to give your body inner balance.
Do you want more energy, less stress, and better recovery? Treat yourself to regular sauna sessions and let your hormones work for your health.
