🌊 The Dive Reflex: A Built-In Survival Mechanism Here’s what happens when you hold your breath and dunk your face in cold water — your body activates what’s known as the mammalian dive reflex, a powerful, ancient response to help you survive in low-oxygen situations. 🫀 Here’s how your body responds: • Heart rate slows down – Your body enters a conservation mode, preserving oxygen. • Blood vessels constrict in your limbs – Less oxygen goes to your fingers and toes, keeping it centralized for yo

❗️The mammalian dive reflex is a fascinating physiological response found in all mammals, including humans. When the face is submerged in cold water, this reflex slows the heart rate and redirects blood flow from the extremities to vital organs like the brain and heart, conserving oxygen and protecting essential functions. This response, though more pronounced in aquatic mammals, can be harnessed in certain medical situations. ‼️ In the context of paramedicine, the mammalian dive reflex can be a

"What on earth is that?" you might ask. 🤔 The mammalian dive reflex is a natural, short-term adaptation that kicks in when your face touches water and you hold your breath. This triggers a series of physiological changes designed to make you a more efficient diver! 💪🏼� These changes include: * Bradycardia (slowing of heart rate to conserve oxygen) * The "spleen effect" (the spleen contracts, releasing more red blood cells into the blood) * Peripheral vasoconstriction (restricting blood flow t

How awesome is this?! "Demonstrating the Mammalian Diving Reflex to the EMT-Basic Academy. The "Diving Reflex" is a reflex of humans, other mammals, reptiles, and birds, triggered by immersion in cold water, that slows the heart rate and diverts blood flow to the brain, heart, and lungs: serves to conserve oxygen until breathing resumes and to delay potential brain damage. It will only work if the water is below 70 degrees Fahrenheit, 21.11 degrees Celsius. Pay special attention to my heart rate
