Saunas are sold as 'fat burners'. They're not. But they have real, indirect benefits that help fat loss work.
What saunas don't do
They don't burn fat directly. The weight you lose in a session is water — back the next time you drink.
What saunas do
Improve insulin sensitivity, increase growth hormone post-session, improve sleep quality and reduce inflammation. All of these support a fat-loss phase.
Where they fit
3–4 sessions per week of 15–20 min, ideally post-workout or in the evening. Combined with a protein-led diet and consistent training, they help. Alone, they don't.
