Regular sauna exposure is not just about relaxation 🔥
It creates a controlled heat stress that triggers cardiovascular and cellular adaptations linked to longevity.
Long-term population studies show that using a sauna around 20 minutes per session, 4–7 times per week, is associated with lower all-cause mortality and reduced risk of fatal cardiovascular events 🫀
Heat exposure increases heart rate, improves vascular function, enhances heat shock protein expression, and supports recovery by shifting the nervous system toward a parasympathetic state.
In simple terms:
Sauna works like passive cardio for your heart and a repair signal for your cells 🧬
Consistency matters more than intensity.
