People can sleep for two days when lonely

There were times when Senni slept for 30 hours but when he woke up he thought it was just a nap.

People can sleep continuously for up to 48 hours when lonely

Whenever scientists study human life in isolated conditions, a common result appears: the cycle of long sleep.

In the 1960s, a classic experiment was performed with two volunteers Josie Laures and Antoine Senni . They lived underground in the Alps in isolated conditions so that scientists made the first research to investigate the impact of this condition on the human body and mind.

Laures set a record for a woman living in an isolated cave for 88 days. Meanwhile, the men's record belongs to Senni for 126 days. The two caves of Laurens and Senni are separated and they only keep in touch with researchers through a checkpoint, who directly monitor their sleep, diet, memory and daily routines. they.

The moment it was brought to the surface, Laurens had to wear sunglasses to adjust to the sunlight.

Researchers never gave Laurens and Senni any clue about the time passed on the ground. As a result, they misjudged the past time in a difference from 2 weeks to 1 month earlier than real time.

That may be the effect of changing the sleep cycle . There were times when Senni slept for 30 hours but when he woke up he thought it was just a nap. When there is no sun to direct sleep, our bodies have a hard time keeping a biological rhythm.

"I am happy that I can sleep more, it makes me forget everything," Josie Laures told Associated Press at the time.

"I can only say that the final stage of the experiment has really become difficult and I feel extremely tired. When I started the experiment, I chose to read books to kill time. But not long after I lost all the inspiration to read, I didn't catch a cold and had a small tent to heat in. When the sound went wrong for the first few days and I tried to fix it, the next few days I listened to music. I could only knit and wait for time to look back at the sunlight. "

Not a meaningless experiment, the results of that time study were very much interested by many scientists. Especially NASA, at that time they were carrying out the task of bringing the man to the moon that President Kennedy had set in the early decade. The result of the experiment can give NASA a visualization of how the merchants will react in a long-space mission.

And at the present time, when NASA is once again preparing for the historic Mars mission, the story is repeated. Although sitting in another spaceship is sitting under a cave, they have similarities.

When there is nothing to do, people simply sleep at any time of the day. Many studies have been developed later on suggesting that even sleep cycles can last up to 48 hours. This may be the starting point for developing deep sleeps if we intend to send the crew to further distant places in the universe.

It can be seen that, in the face of loneliness and darkness, mental fatigue seems to be the biggest problem people face. Many studies similar to the experiment with Laurens and Senni in 1965 were conducted later to better understand the state of people in isolated conditions.

These negative impacts are not difficult to imagine but in the future scientists still need a complete and accurate conclusion. In 1965, Antoine Senni was 126 days underground, in the 2030s a Mars flight could last 300 days and if we still intend to go further, similar experiments will still have to be proceed.
