In 2021, Spanish athlete Beatriz Flamini entered a cave 230 feet underground and stayed there completely alone for 500 days. She had no sunlight, no clocks, and no direct human contact. The goal was to study what extreme isolation does to the human mind and body when someone is cut off from time. Scientists monitored her from outside the cave, tracking the effects of isolation, darkness, and the loss of a normal sleep cycle. When Flamini finally emerged in April 2023, she was shocked to learn how long she had been underground. She thought only about 160 days had passed.
