Key Takeaways Just 5 minutes of warm water immersion at 40–41 °C increased femoral artery blood flow by 45.9 % and reduced leg vascular resistance by 29.1 % in a controlled study (Sasaki et al., 2021). Warm water triggers vasodilation through nitric oxide release — the same mechanism behind exercise-driven vascular health improvements. Percussive massage…
