BEWARE OF ODD WORK SCHEDULES
Of, that is, working third shifts, working late into the night, working too many hours.  This not only affects air traffic controllers; this affects many in our society.  And it can hurt your health:
"Czeisler said the potential danger isn't limited to air traffic controllers, but can apply to truck and bus drivers, airline pilots and those in the maritime industry. Who else? Factory workers, police, firefighters, emergency workers, nurses and doctors, cooks, hotel employees, people in the media and others on night or changing shifts.
"We live in a very sleep-deprived society where many people are burning the candle at both ends," Czeisler said. He said that a half-century ago, just 2 percent of people slept six hours or less per night; today it's 28 percent.
Dr. William Fishbein, a neuroscientist at the City University of New York, said that when people work odd shifts "it mucks up their biological rhythms."
Hormones are synchronized with the wake-sleep cycle. When people change shifts, the brain never knows when it's supposed to be asleep, so this affects how people function.
People who change shifts every few days are going to have all kinds of problems related to memory and learning, Fishbein said. This kind of schedule especially affects what he called relational memories, which involve the ability to understand how one thing is related to another.
In addition to drowsiness and inability to concentrate, people working night shifts are more subject to chronic intestinal and heart diseases and have been shown to have a higher incidence of some forms of cancer. The World Health Organization has classified shift work as a probable carcinogen."
