Delve into the tale of Beatriz Flamini, the Spanish mountaineer who spent 500 days in a cave, losing track of time, and potentially breaking a world record. Let’s uncover the secrets of the human brain and the mysteries of circadian rhythms through this extraordinary adventure.
Once upon a time, in the mountains of Spain, a fearless woman embarked on an epic journey. Her name was Beatriz Flamini, and she decided to spend 500 days inside a cave, 230 feet deep, with practically no contact with the outside world. This incredible adventure began on November 20, 2021, and ended on April 14, 2023. Now, as she emerges from her subterranean retreat, we have the privilege of exploring her extraordinary tale.

Living in total isolation, Flamini found solace in exercise, painting, knitting, and reading. She devoured 60 books during her time underground and documented her experience on two GoPro cameras. Interestingly, she stopped counting the days after day 65, losing all perception of time.
As part of a research project, Flamini’s extraordinary journey was monitored to study the effects of social isolation, lack of contact, and the absence of a day-night cycle on the human brain and circadian rhythms. Circadian rhythms are physical and behavioural changes that occur across a 24-hour cycle, controlled by a “master clock” in our brains. When we experience jet lag, it’s because our circadian rhythms are out of sync with the local time.
Flamini’s experience offered a unique opportunity to study how our brains adapt to such extreme conditions. Remarkably, she coped well with her ordeal. Upon emerging from the cave, she said, “I didn’t feel anything when I saw the light because to me it felt like I’d only just gone in there, so I didn’t have that sensation of missing the light and the sun and all that’s out there.”
The only people Flamini had contact with during her stay were her support team, who provided fresh food, clothes, and removed her waste. She remained completely unaware of world events and even personal tragedy, staying true to her commitment to total isolation.





Flamini’s cave stay potentially broke the Guinness World Record for the “longest time survived trapped underground,” currently held by the 33 Chilean and Bolivian miners who spent 69 days trapped in 2010. However, her record has yet to be confirmed by Guinness.
Social isolation has previously been linked to increased risks of depression, dementia, some types of cancer, and cardiac issues. However, Flamini seemed to have found her own ways to cope with her isolation. She shared, “I didn’t talk to myself out loud, but I had internal conversations and got on very well with myself.”
According to Flamini, staying conscious of one’s feelings is essential in such situations. She added, “If you’re afraid, that’s something natural but never let panic in or you get paralyzed.”
As we stand in awe of Beatriz Flamini’s incredible underground adventure, her experience sheds light on the adaptability of the human mind and the mysteries surrounding our circadian rhythms. Her resilience and positive attitude, coupled with the findings from the research, will undoubtedly inspire further exploration of our brains’ capabilities and the extraordinary ways we can adapt to isolation and the absence of time.
So, next time you find yourself feeling isolated or disconnected from the world, think of Flamini’s journey and the lessons she’s shared. Remember that our minds are capable of remarkable feats, and perhaps, like Flamini, you too can find solace in self-discovery and the pursuit of knowledge in the most unexpected of places.
