In 1962 a 23 - twelvemonth - quondam geologist lived alone in a cave for two months . He had no problem with it . In 1972 , he tried it again , and well-nigh lost his brain . Naturally , there are people who choose to isolate themselves , but what would pass to someone whose main goal in life was n’t enforced solitude ?
Michel Siffre , a 23 - year - old French geologist , decided to test it out . He would go into a cave and rest alone for a point of metre . At first he thought 15 daylight would do it ; over time he decide that he needed to go bigger and design a sojourn for two months , with little artificial luminousness , no clock , and a telephone that only shape one way . He piece a cave in the Alps , which give the advantage of being geologically interesting , as well as below - freeze temperatures and 98 % humidity . Constantly cold and damp , he only freaked out for one day — singing and saltation until he was shopworn out , otherwise he take up very well . When his squad descend to get him , he thought they were a month and a one-half early . His metre horse sense was compressed — during his phone “ conversations ” with his squad , he counted off his estimation of 120 seconds . It took him five minutes . He also called whenever he eat , log Z’s , or woke up . Without raw brightness level , he still fell into a 24 - hr rhythm — which turned out to be the most scientifically significant discovery of his time in the cave .
The next sentence he proceed down into a cave , he did n’t have as dainty a stop . This cave was in Texas . Siffre was well - equipped and the cave was more pleasant in terms of temperature and air . interior redstem storksbill had become a hot issue in science since his last stoppage in a cave , and Siffre wanted to tamper with his . He was endeavor to get on a 48 - hour cycle .

After two month he became horrifically depressed . His cycles eventually fluctuated between 18 and 52 hours . His lowest moment came when , after he ’d spend day watching a computer mouse reave his solid food stores , he tried to catch it to have some kind of fellowship , and unintentionally killed it . During the experiment he had electrode attached to his fountainhead , to monitor his progress . One day there was a lightning tempest , and the electrode render him agonizing shocks . He was too disoriented by clinical depression to realize how to make the botheration stop until he ’d been blow out of the water three times .
Despite the extreme depression , Siffre kept up doing closing off experiments in caves . He considered his six - month isolation experimentation exasperate by the fact that the atmospheric state in the cave ruin the record musician and magazines he used to keep his mind occupied . grant , that probably did n’t help , but how much music can anyone take heed to ?
Would you like a slight isolation ? How long would you opine would be perfect ? How long before you could n’t stick out it anymore ?
