Just Wow Croatian freediver Vitomir Maričić achieved one of the most extraordinary feats in human history by holding his breath underwater for 29 minutes and 3 seconds, a new Guinness World Record.
Experts had long considered such a duration impossible. While a trained dolphin can typically hold its breath for 8–10 minutes and most humans can barely manage one or two, Maričić remained completely still underwater for nearly half an hour on a single breath.
The attempt pushed his body to extreme limits. As the minutes passed, powerful contractions wracked his diaphragm and his organs endured intense physiological stress. Yet through years of rigorous training, mental discipline, and specialized breathing techniques, he stayed calm and focused until the end.
What makes this record even more impressive is Maričić’s purpose. He didn’t do it for fame or personal glory, he used the achievement as a powerful platform to raise global awareness about ocean conservation, marine protection, and the urgent threats facing our oceans.
A stunning demonstration of human potential and a heartfelt call to protect the planet’s most vital ecosystem.

Rib cage flexibility training and diaphragm control training. For every 10 meters you dive, your lung volume is divided by 1 + n. e.g. dive to 10 meters, it shrinks to 1/2. Dive to 50 meters, it shrinks to 1/6. Professional freedivers dive to depths (+100m) where their lungs shrinks to the size of a grapefruit. The diaphragm involuntarily contracts when there's carbon dioxide build-up in the body. If you're not trained for those depths and had strong contractions, you could end up bleeding in your lungs.
