NASA Bed-rest Study Participant
One small nap for a man, one giant sleep for mankind! In what has to be one of the strangest scientific studies subsidized by the American taxpayer, NASA will pay you up to $18,000 to lay in bed for 70 to 90 straight days [source: Ziegler].
Test subjects in NASA's bed-rest studies help scientists measure the effects of microgravity on the human body and develop "countermeasures" to maintain the health and fitness of future astronauts who may one day make the roughly 250-day trip to Mars [source: Smith].
If lying around all day for three months sounds like a dream job, think again. Subjects must lay in beds that recline at a six-degree angle toward the head to mimic blood flow in low gravity. Sinus headaches are one thing, but then there are the, uh, logistics of using the bathroom and eating without sitting up. Participant Beth Ann Shriber, who completed a marathon 90-day bed rest study called it a matter of endurance [source: Dean].
If long-haul studies aren't your thing, check with local universities and research hospitals about participating in a sleep study. In 2015 Harvard Medical School was offering to pay healthy young participants $7,500 for a 32-day sleep study or an easy $600 for two nights of interrupted sleep to test the effects of sleep apnea on learning [source: Harvard Medical School].
