Study Notes
Michel Siffre's Underground Experiments
- In 1962, Michel Siffre, a 23-year-old French speleologist, spent 63 days living in total isolation in a subterranean cave without access to a clock, calendar, or sunlight.
- Siffre's goal was to discover how the natural rhythms of human life would be affected by living "beyond time," eating and sleeping only when his body told him to.
Background and Motivation
- Michel Siffre was a geologist by training.
- In 1961, Siffre discovered an underground glacier in the Alps, 70 kilometers from Nice, which led to his idea of preparing a geological expedition.
Later Experiments and Contributions
- Over the next decade, Siffre organized over a dozen other underground time isolation experiments.
- Siffre returned to a cave in Texas in 1972 for a six-month spell.
- His work helped found the field of human chronobiology.
