🤿 The Mammalian Diving Reflex: The Body's Built-In Oxygen-Conservation Switch

Explore the mammalian diving reflex, the automatic physiological response triggered by cold water on the face that slows the heart, redirects blood flow, and helps conserve oxygen.

Medical Technology & Imaging Physics3DModerate60 FPS

This simulator visualizes how facial cold-water exposure triggers coordinated changes in heart rate and blood vessel constriction through the mammalian diving reflex.

🔬 What It Demonstrates

This simulator visualizes how facial cold-water exposure triggers coordinated changes in heart rate and blood vessel constriction through the mammalian diving reflex.

🎮 How to Use

Adjust the water temperature and immersion duration to see how the simulated heart rate, peripheral blood flow, and nervous system activation respond in real time.

💡 Did You Know?

Infants have an especially strong diving reflex, and some human breath-hold divers can voluntarily train their bodies to intensify this response for deeper, longer dives.
