Stefania Follini was isolated in a cave for 131 days for science

To study circadian rhythms, scientists recruited a 27-year-old Italian interior designer to live in a small shelter built in a cave below Carlsbad, New Mexico for several months. Soon, her sense of time and her body functions all changed dramatically.

This interesting program compares Stefania with the miners trapped for 69 days in the 2010 Copiapó mining accident.
