Weirdest Sleep Experiments Infographic

The very nature of being human means that we strive to understand the world around us. Scientists have long considered experiments the best way to test a hypothesis and draw a conclusion.

Over the last century, scientists have begun to study sleep more and more. We know it’s necessary yet we don’t fully understand it. Such a vital function could contain so many important discoveries that we haven’t yet come across.

In this infographic we look at some of the most bizarre sleep experiments. What were they, who ran them and why? Did we learn anything from them or did they go horribly wrong?

Weirdest Sleep Experiments Senosry Overload: Method - Subjects endured: eyelids taped open, loud music, flashing strobe lights, shock electrodes on lges. Observations - Two of the three subjects went to sleep within the first 12 minutes. Conclusion - The urge to sleep is so powerful that it can override deprovation techniques. The Nail Biter Sleep Experiment: Method - A group of young biys who were chronic nail biters were spoken to as they slept. "My fingernails taste terribly bitter", was repeated to them throughout the night. Observations - The experiment had to be repeated nightly over the course of several weeks. Conclusion: 40% of the boys were cured, but a later attempt at recreating the experiment resulted in 0% success. This implies that someone may have been pretending or lying. Sleep deprivation: Method - Puppies kept awake through forced walking and handling. Observations: The first puppy died within 96 hours. The last after 143 hours. If the puppies has been starved of food rather than sleep, they would have stayed alive longer. Conclusion - Sleep is mre important than food. Lack of sleep on the immune system Method - Scientists collected nightly sleep data on 164 healthy individuals for 1 week. They then quarantined the same people in a hotel and gave them nose drops containing Rhinovirus, which is responsible for the common cold. They let the hosts' immune systems do the rest. Observations - Those who slept fewer than 5 hours a night were 4.5 times more likely to get sick than those who slept 7 hours or more. Conclusion - Sleep protects against the common cold by increasing the body's natural defence system . Isolation and the concept of time: Method - French geologist Michel Siffre spent 2 months in a subglacial ice cave in 1962. He made no effort to track time, but slept and ate only when his body told him to. Observations - He perceived time as passing more slowly than it was but he managed to keep a regular sleep pattern, going to bed and waking up at the same times every day. Conclusion - Humans have an internal clock. This experiment helped found the field of human chronobiology,
