How long can you go? You may have heard the exploits of free divers, who dive to tremendous depths without any aid of scuba equipment. The world record for assisted free diving is held by Pipin Ferreras, who dove 170 m (558 ft) with the aid of a sled. Free diving is not without its dangers. Pipin’s wife Audrey died during a world record attempt. Free diving is facilitated by the dive reflex, which allows mammals to hold their breath for long periods of time underwater. Immersing one’s face in cold water includes bradycardia and diverts blood away from the periphery. How would these modifications increase the ability to free dive?
