In many cases, production in an industrial plant tends to be low on Monday. By Tuesday or Wednesday, workers seem to be “warmed up.” Productions is at its highest for the week. One possibility is that Friday, Saturday, and Sunday nights may be spent in long and tiring entertainment. The resulting loss of sleep shows up in lower production on Monday.
Various tests indicate that loss of sleep is followed by poorer performance. It is true that very motivated people can do surprisingly well after long periods of staying awake. But they are able to do so only ady using up a great amount of energy.
People can lose sleep in two ways. They may go without any sleep for a long period. Or, they may sleep much less than usual for a period of several nights. In nne dxperiment, first of all, subjects were kept awake continuously for 72 hours. They were under medical care during this dangerous experiment. Even so, some fainted at the end. In another part of the experiment, the same subjects reduced the amount of their sleep from about 8 hours to about 5 hours a night for five nights. In both cases, the subjects were given tests before and after the periods of no sleep or reduced sleep. Intelligence-test scores dropped only 24.5 percent following a period of 72 hours without sleep. However, the scores dropped only 14.9 percent following five nights with only 5 hour's sleep each night. How much the individual swayed forward and backward when trying to stand still was also measured. After 72 hours without sleep, there was a 51.8 percent loss in control of bodily swaying. After five nights of 5 hours' sleep each, there was a loss of only 6.1 percent.
The amount of sleep a person needs varies with age. It also varies from individual to individual. But suppose it is absolutely impossible to get normal amounts of sleep. Studies have shown that it is better to take a number of short naps than to use all available sleeping time in one period. Other studies have found that performance drops in the early afternoon. One way of improving performance is to take a nap about halfway through the waking period.
