Record depths in freediving: a journey toward the limits
The stories and records in freediving and the amazing physiology behind reaching depths beyond 300 meters.
Records in freediving push the limits of what was thought possible for the human body.
Categories of record depths
No Limits
The category that allows using a weight for descent and a balloon for ascent. It achieves the deepest numbers, some of which have exceeded 300 meters.
Free Immersion
Descent by any means and ascent by pulling only. Harder than No Limits because the body ascends by its own effort from vast depths.
Constant Weight
Using fins only for descent and ascent. It is the most respected standard in freediving circles.
What happens at record depths
At 200 meters the lungs compress to less than a liter, a quarter of their normal size. The pressure equals 21 times atmospheric pressure. The trained human body deals with this in an amazing way.
Where is the real limit?
Scientists do not yet know the real limit of the human body in freediving. Every new record redraws the map.
Records in freediving remind us that the limits of the human body are always farther than we imagine.
