The video explores the challenges of water pressure in free diving, featuring Megan Haney Greer, a professional free diver. It explains how water pressure increases with depth, affecting the human body, particularly the lungs. As divers descend, their lungs compress, reducing buoyancy and allowing them to sink. The video also highlights the risks of free diving, such as shallow water blackout, and emphasizes the importance of safety and awareness of one's physical condition.
