Episode notes
Deepest Unaided Freedive
- The deepest unaided freedive is 334 feet, requiring divers to hold their breath for an extended period.
- This feat surpasses the limitations perceived by scientists regarding human capabilities.

- Water pressure doubles every 30 feet, significantly reducing lung size at depth.
- Freedivers experience this transformation, with lungs shrinking to the size of fists at 300 feet.

- Scientists initially believed that humans couldn't survive extreme freedives due to pressure.
- However, the discovery of the mammalian dive reflex proved these assumptions wrong.
