Heat Adaptation & Sauna: The Endurance Hack
Regular sauna use trains your body to handle heat and stress — and may boost endurance the way altitude does.

Heat is stress, and the body adapts to stress. Used deliberately, the sauna is a powerful tool for fighters.
What heat adaptation does - Plasma volume — regular heat exposure can expand blood volume, supporting endurance. - Stress resilience — practising calm while uncomfortable trains the same nervous-system skill you need late in a fight. - Recovery — heat relaxes muscles and aids the wind-down before sleep.
How to use it - Post-training or on rest days, not before hard work. - Build tolerance gradually — short sessions first. - Hydrate and replace salts around it.
The sauna trains the same composure you'll need in the championship rounds.
A cheap, old tool with a real, modern edge.
