The Institute for Space Medicine and Physiology (Medes) will pay 24 lucky individuals $17,000 each just to sleep. The sleeping project is part of the weightlessness research which the institute is very keen on finding out. If you think it's easy money, think again because NASA says it's not as easy as it sounds like.

The purpose of the research was to mimic weightlessness in the International Space Station, Civilized reported. According to Dr. Arnaud Beck, the idea was to reproduce the weightlessness in the ISS to which the volunteers will be subjected to a whole series of tests and measurements for the first two weeks. Volunteers also have to sleep for 60 days with their heads slightly tilted downwards.

After the 60-day period, the volunteers will be rehabilitated to examine the effects of horizontal living on their bodies. If that sounds like the easiest way to earn money, think again. This kind of research has been performed by NASA before and according to one participant, he hated the space agency for it.

Andrew Iwanicki took part of the NASA project in 2014. They were required to sleep for 70 days and paid $18,000 for the effort. He documented boredom as well as severe headache and backache and at one point Iwanicki said he cursed NASA for eternal damnation because of it.

The Medes job is in France, Irish Examiner reported. They're looking non-smoking, physically active, and healthy young men of 20 to 45 years old. They should have a body mass index between 22 and 27.

Those who are chosen to participate in the study and take home $17,000 will be sleeping with one bed in contact with the bed at all times for 60 days. Half of the volunteers will be given specific medication to counter the side effects of weightlessness. The medication includes antioxidant and anti-inflammatory food supplements.
