Fifteen volunteers emerge from isolation study in French cave after spending 40 days underground

A group of 15 people taking part in an experiment where they cut themselves off from the world have re-emerged from a cave in France after 40 days.

Leaving their cave dwelling on Saturday, the group from a scientific experiment to say that time seemed to pass more slowly in their cavernous underground abode, where they were deprived of clocks and light. 

The 15 left their voluntary isolation in the Lombrives cave to a round of applause and basked in the light of day while wearing special glasses to protect their eyes after so long in the dark. 

‘It was like pressing pause,’ said 33-year-old Marina Lançon, one of the seven female team members in the experiment, adding she didn’t feel there was a rush to do anything.

Although she wished she could have stayed in the cave a few days longer, she said she was happy to feel the wind blowing on her face again and hear the birds sing in the green trees of the French Pyrénées. 

For 40 days and 40 nights, the group lived in and explored the cave without a sense of time as part of the Deep Time project. 

There was no sunlight inside, the temperature was 10 degrees Celsius (50 F) and the relative humidity stood at 100%. The cave dwellers had no contact with the outside world, no updates on the pandemic nor any communication with friends or family. 

Scientists at the Human Adaption Institute leading the 1.2 million-euro (£1.05 million) ‘Deep Time’ project say the experiment will help them better understand how people adapt to drastic changes in living conditions and environments, something much of the world can relate to because of the coronavirus pandemic.

Despite having been underground for 40 days, some members of the group had lost their sense of time, with at least one member estimating they had spent 25 days in the cave.

‘And here we are! We just left after 40 days … For us it was a real surprise,’ said project director Christian Clot, adding for the majority of the participants, ‘in our heads, we had walked into the cave 30 days ago.’ 

In partnership with labs in France and Switzerland, scientists monitored the 15-member group’s sleep patterns, social interactions and behavioral reactions via sensors. 

One of the sensors was a tiny thermometer inside a capsule that participants swallowed like a pill. 

The capsules measure body temperature and transmit data to a portable computer until they are expelled naturally.

The team members followed their biological clocks to know when to wake up, go to sleep and eat. They counted their days not in hours but in sleep cycles.

On Friday, scientists monitoring the participants entered the cave to let the research subjects know they would be coming out soon. 

They said many in the group miscalculated and thought they had another week to 10 days to go.

“It’s really interesting to observe how this group synchronizes themselves,” Clot said earlier in a recording from inside the cave. 

Working together on projects and organizing tasks without being able to set a time to meet was especially challenging, he said.

Although the participants looked visibly tired, two-thirds expressed a desire to remain underground a bit longer in order to finish group projects started during the expedition, Benoit Mauvieux, a chronobiologist involved in the research, told The Associated Press.
