Yes, sleep. How often have you tried to stay awake for nearly 24 hours? Maybe to work, study for an exam, to finish a project, or just having fun partying with friends. No matter the reason sleep deprivation is a big risk, both for your health and your environment.

Twenty-four hours without sleep can produce as much impairment as being legally drunk.

As I was looking through www.howstuffworks.com I came across an interesting article. How Can Someone Stay Awake for 11 days? A man in Cornwall, England, actually went 11 consecutive days without a wink of sleep.

The Guinness Book of World Records no longer acknowledges sleep deprivation attempts because they feel that they’re too dangerous. In 1964 the record of 274 hours without sleep was set. This record was in the Guinness Book until they removed the category entirely in1989

Consequently, sleep deprivation is a major contributor to auto accidents and may have contributed to disasters such as the explosion at Chernobyl and the Exxon Valdez crash. Sleep deprivation is also a major concern for people working long hours (such as doctors and night shift employees) and for anyone suffering from sleep apnea, which causes high blood pressure, stress and low oxygen levels in the blood. Repeated sleep deprivation can increase your appetite and lead to weight gain.

Long-term sleep deprivation can cause vision problems, hallucinations, paranoia, mood swings, difficulty communicating or understanding others, a compromised immune system and depression.
