Michel Siffre is a French underground explorer, adventurer, and scientist born on January 3, 1939, in Nice. He founded the French Institute of Speleology in 1962 and conducted significant experiments on human perception of time during prolonged periods of isolation underground. In 1962 and 1972, he undertook extensive stays in caves, discovering that without time cues, humans can adapt to a 48-hour circadian rhythm. His findings have contributed to our understanding of time perception, with implications for NASA astronauts who reported similar experiences.
