A 50-year-old Spanish woman voluntarily lived in a 70-metre-deep underground cave for 500 days. She had no contact with the outside world. She did it as an experiment to learn more about our sleep-wake rhythm and the capabilities of the human brain.

Since November 20, 2021, Beatriz Flamini has been living in a cave in the Spanish province of Granada. Today she saw daylight for the first time. She called her experience in the cave “excellent”.

Flamini filmed her adventure. Watch how she lived in the cave and climbed out after all this time:

Woman sees daylight for the first time after 500 days in cave

Flamini loves extreme sports, is a mountain climber and caver. As a caver she is engaged in the study of caves.

To get out of the cave today, she received support. That was necessary because she “lost her balance”. She craved a shower the most because she hadn’t been able to shower for a year and a half.

In the cave she was engaged in knitting, sports, painting, drawing and she has read sixty books. Food was hoisted down via a large bag of cables.

No cell phone or watch

Flamini did not have a mobile phone or a watch with him. She did have a laptop at her disposal, but with it she could only send information to the outside world and not receive it. She filmed her adventure with two small cameras.

During its isolation in the cave, the project called ‘Timecave’ was closely monitored by scientists from the Universities of Granada and Almería. They want to investigate the effects of complete isolation and see if it led to neuropsychological and mental changes.

Flamini holds a world record with her cave confinement. She has lived in a cave for the longest time ever.
