[00:00:00]Did you know that rising too fast from deep water can turn your blood into a fizzy drink that kills you? It's called decompression sickness and it's one of the most terrifying ways your own body can betray you. Here's what happens.

[00:00:11]When you dive deep, the crushing pressure forces nitrogen from the air you breathe to dissolve into your blood and tissues. Think of it like opening a soda bottle. Under pressure, everything stays dissolved. But if you rise too quickly, that nitrogen turns into bubbles. Tiny gas bubbles racing through your bloodstream. They block blood flow to your brain, your spine, your heart.

[00:00:34]>> [music] >> Commercial divers call it the bends because victims twist in agony as the bubbles attack their joints. But it gets worse. The bubbles can cause strokes, paralysis, death. In 1945, [music] four divers working on a sunken ship off the coast of New Jersey surfaced too fast. All four were found writhing on deck, blood foaming from their mouths.

[00:00:54]Two died within minutes. Your blood, the very thing keeping you alive, becomes [music] the weapon that kills you. All because you wanted to breathe. Again.
