# Exploring the Effects of Isolation: A Year and a Half in a Cave
Written on
Chapter 1: The Isolation Experiment
What impact does extreme isolation have on individuals? To shed light on this question, a Spanish athlete undertook an extraordinary experiment, spending a year and a half in solitude within a cave.

Section 1.1: Beatriz Flamini's Journey
On April 12, 2023, Beatriz Flamini recounted her experience, stating, “I was asleep—at least I thought I was—when they came for me. I thought something must have happened. I asked: Is it already…? Impossible. I haven’t finished my book yet.” A week prior marked 500 days since Flamini entered a cave near Grenada. In November 2021, at the age of 48, she embarked on one of the most extreme isolation studies known. Her decision to detach from the world and sunlight for a year and a half led her to a cave situated 70 meters deep. A smaller-scale experiment had previously been conducted in France.
Flamini's venture was overseen by scientists from the universities of Almeria, Granada, and Murcia, who maintained limited contact with her. She chose to remain oblivious to current events, unaware of the outbreak of war in Ukraine, the passing of Queen Elizabeth, or the end of pandemic restrictions.
Section 1.2: The Perception of Time
Beatriz Flamini, an avid mountain climber and extreme sports enthusiast, was mentally prepared for her extended isolation. After emerging from the cave, she attributed her endurance to her determination and her comfort in solitude. She refrained from speaking aloud to herself, honoring the cave's stillness, and engaged in activities she loved, such as reading, writing, drawing, and knitting. This focus helped her navigate both challenging moments, like the sudden influx of flies, and joyful ones.
However, after just two months, she began to lose track of time, a phenomenon that was anticipated. When the team arrived to conclude her experiment, Flamini was astonished, believing only 160–170 days had passed, while in reality, she had spent far longer.
How does one’s sense of time shift in isolation? Ruth Odgen, a psychologist at Liverpool John Moores University, explores this topic in The Conversation. With over a decade of research on time perception, Odgen explains that the passage of days is usually marked by the cycles of sunrise and sunset, while work and social interactions delineate hours. In the absence of light and companionship, many time markers vanish.
Chapter 2: The Mechanism of Time Perception
In her unique situation, Flamini had to rely on her mental processes to gauge time. Odgen notes, “One way to register the passage of hours is through memory. If we lack awareness of how long we’ve engaged in an activity, we turn to memories formed during it to estimate time. The more memories we create, the longer we perceive time has passed.”
This explains why busy days seem to stretch on longer than uneventful ones. In Flamini’s case, the lack of social interaction and external information likely diminished the memories she created, making her stay feel shorter than it truly was. Furthermore, her relationship with time differed from that of others; she had no obligations or scheduled events to adhere to.
“Her life followed its own rhythm,” Odgen concludes. “She chose when to sleep, eat, or read, rendering the passage of time less significant.”
In summary, Beatriz Flamini's extraordinary experience in solitude highlights profound insights into the nature of time and the human psyche.
