Lily begins her bath by calmly submerging herself underwater, gracefully diving three times for four minutes each. As the third minute approaches during her last dive, she starts to struggle, feeling the pressure build in her chest as her breath becomes harder and more complicated. Desperately fighting for air, she tries to scream underwater, but the bubbles merely escape silently. Finally, gasping for breath, she resurfaces, her goggles and diving mask still in place, relieved to fill her lungs with air once again.Holding one's breath for four minutes is an incredibly challenging feat that requires intense mental and physical discipline. As time passes, the body's urge to breathe intensifies, causing discomfort and sometimes panic. The diaphragm contracts, signaling the need for oxygen, while carbon dioxide levels rise, triggering the urge to exhale. For most people, reaching the four-minute mark without prior training or conditioning is extremely difficult and potentially dangerous, as it pushes the body to its limits.
