How important is the dream?
Several famous accidents can be attributed to lack of sleep. The third officer of the oil tanker Exxon Valdez that ran aground on March 24, 1989 and spilled 11 million gallons of crude oil had been awake for 18 hours before the accident. The Walmart van driver who struck Tracy Morgan’s limousine truck in 2014 that seriously injured him and killed one of his comedy writers had been awake for more than 24 hours. Workers at 3 Mile Island were deprived of sleep and did not notice the rise in core temperature that resulted in the 1979 nuclear accident. The fact that certain managers involved in the launch had only slept two hours before arriving at work at The 1 a.m. launch morning may have contributed to the Challenger explosion in 1986.
How much is enough sleep? Sleep needs vary from person to person. They vary by age, lifestyle, and health. Work schedules and stress can affect the amount of sleep someone needs. The National Sleep Foundation recommends 7 to 9 hours of sleep per night for adults ages 26 to 64. They point out that an amount of 6 to 10 hours per night may be appropriate.
