Maurizio Montalbini (Senigallia 4 September 1953–Pieve Torina 19 September 2009) was an Italian sociologist and caver who had lived in complete isolation in an underground chamber multiple times since 1986.
On December 14, 1986, Montalbini entered the Frasassi Caves of the Apennine Mountains, near Ancona. A video feed was set up to monitor him from the surface. He emerged on July 12, 1987, breaking the world record for complete isolation. An Ancona local named Stefania Follini heard of his exploits and decided to attempt it herself; NASA sponsored her stay in a cave in New Mexico. Her menstrual cycle stopped, and she began a sleep cycle of waking for 23 hours at a time and sleeping for 10 hours. Both Follini and Montalbini found that time passed quickly underground.
Throughout 1993 Montalbini stayed in a cave in Pesaro. He again lost his sense of time, thinking it was only June when he was called to the surface in December. More precisely, he entered on December 6, 1992 and got out on December 5, 1993, thinking it was June 6, 1993. At that time, his immune defence system fell from a level of 23 to 0, and then after 10 days it recovered to a level of 2.5.
In October 2006 Montalbini entered a cave called "Underlab" with the intention of spending three years there. He planned for it to be his final experiment, but hoped it would provide valuable insight into the natural cycles of the body. This stay ended up lasting just over 260 days.
Montalbini would eat pills for meals while in the cave, but also brought along honey, nuts and chocolate on his most recent trip.
