Max G. Levy: Les saunas peuvent-ils nous faire vivre plus longtemps ?

Les saunas peuvent-ils nous faire vivre plus longtemps ?

Sauna finlandais, bain romain, onsen japonais et huttes de sudation des peuples autochtones d’Amérique ne sont que quelques exemples illustrant comment, à travers le monde, les cultures considèrent depuis longtemps l’exposition à des températures extrêmes comme thérapeutique. Mais aujourd’hui, les scientifiques commencent seulement à comprendre comment et pourquoi cela pourrait être le cas. Alors, que se passe-t-il exactement dans notre corps lorsque nous ressentons de la chaleur ? Max G. Levy enquête.

Frequent sauna bathing, long cherished in Finland and found in cultures worldwide, has been linked to better heart health and longevity. A study following over 2,000 Finnish men for 20 years revealed that those who used saunas four to seven times a week had lower blood pressure, healthier cholesterol, and reduced overall mortality. Scientists have discovered that regular heat exposure triggers responses in the body similar to moderate exercise, boosting blood flow and supporting muscle recovery. While these findings are promising, researchers caution that more studies are needed to fully understand the benefits and risks for different populations.

Sauna Culture Unlocks Surprising Pathways To Heart Health

Decades of research in Finland revealed that frequent sauna bathing was linked to improved heart health and lower mortality rates among men. Cultures worldwide, from Roman bathhouses to Japanese onsen, have long embraced the healing power of heat. Modern science now shows that regular exposure to high temperatures can trigger exercise-like effects, boost recovery, and regulate inflammation. While promising, these findings raise new questions about how heat interacts with our biology and which groups stand to benefit most.
