Regular sauna use has been linked to lower all-cause mortality and improved cardiovascular fitness, including higher VO₂ max and better exercise performance. Heat exposure elevates heart rate and circulation, strengthening the cardiovascular system similarly to moderate aerobic exercise. It also boosts endurance by increasing plasma volume, enhancing thermoregulation, and speeding recovery through reduced inflammation and muscle soreness. Together, these adaptations support performance gains and long-term heart health 💪
