Michel Siffre, the pioneer of chronobiology, revolutionized the study of biological rhythms with his cave experiments. Inspired by the space race, in 1962 he isolated himself at a depth of 130 meters for two months without access to natural light or clocks, allowing him to discover how the human biological clock adapts in the absence of time references. His experiments revealed that our bodies follow an internal cycle that is not dependent on a 24-hour clock, showing how time slows down and affects our perception. This video explores his discoveries, from his first experiment to his final attempt to understand how aging affects our perception of time. Discover how Siffre's findings influenced NASA and modern science.
