Meet Michel Siffre: The man who disappeared underground for science
In 1962, Michel Siffre isolated himself in a cave for over two months, cutting off all external time cues. His experiment revealed that the human body possesses an internal clock independent of daylight, a discovery that revolutionized sleep science and chronobiology. This groundbreaking research continues to influence our understanding of time and biological rhythms.
