Regular sauna exposure (2 to 7 times per week, at approximately 79 °C for over 20 minutes) helps optimize longevity and supports long-term heart health.

This advice is based on solid wellness data but calls for an important nuance regarding the nature of the evidence. The figures cited come from a major prospective observational study conducted by Jari Laukkanen and his team (2015) on more than 2,300 participants followed for two decades. This research clearly shows a strong link between regular sauna use and better longevity, with notable decreases in the risk of cardiac-related death. Nevertheless, as this is an observational study and not a randomized controlled trial (RCT), it cannot be excluded that other healthy lifestyle habits also account for these results. However, synthesis studies confirm that heat exposure mimics the benefits of moderate physical exercise by engaging the heart and improving circulatory flexibility. Practicing this protocol is therefore an excellent strategy for recovery and vitality, even if the reduction percentages should not be taken as absolute guarantees.
