Did You Know!
The human body has a built-in defense against drowning: This is called the “mammalian diving reflex.” When your face is submerged in cold water, your heart rate slows, blood flow is directed to vital organs like the brain and heart, and non-essential bodily functions are reduced to conserve oxygen. This reflex can give you extra time in an emergency situation, like when you’re submerged in cold water.
