## Takeaway

Regular sauna use may improve health and longevity by inducing beneficial physiological adaptations to heat.

## The question

What are the physiological responses and health benefits associated with sauna use, and how might it extend healthspan?

## Hypothesis

Repeated sauna use, through mild hyperthermia and thermoregulatory responses, may optimize the body's response to heat and extend healthspan.

## Methods

This is a review article that synthesizes findings from observational, interventional, and mechanistic studies on sauna use. It describes sauna practices, physiological responses to heat stress, molecular mechanisms, health benefits, and concerns.

## Results

Sauna use involves short-term passive exposure to high temperatures (45 °C to 100 °C), inducing mild hyperthermia and a thermoregulatory response involving neuroendocrine, cardiovascular, and cytoprotective mechanisms. Repeated use acclimates the body to heat, likely via hormesis. Large prospective cohort studies show strong dose-dependent links between sauna use and reduced morbidity and mortality.

## Conclusion

Sauna use appears to be a probable means to extend healthspan by eliciting beneficial physiological and molecular responses, as supported by various studies showing reduced morbidity and mortality.

## Limitations

This review article does not present new experimental data but rather summarizes existing research. Specific limitations of the reviewed studies are not detailed in the abstract.
