Activities coffee drinkers generally done to reduce drowsiness workers who come. But you probably would never have guessed if it actively coffee can also make workers more productive. Researchers at the London School of Hygiene and Tropical Medicine found that caffeine can help improve memory and concentration and can reduce the number of workers they make mistakes. Even for those who work the night shift, coffee has the same effect powerful this by napping.The researchers also suggested that drinking coffee can help reduce workplace accidents, traffic accidents involving workers on duty the night shift and even medical mistakes made by doctors to call, or attending physicians.
This result is known after a team of researchers analyzed 13 separate studies from around the world involving shift workers aged around 20s. Some participants were given caffeine while others were given a placebo to compare the effects. Working conditions in simulated night shift in a laboratory. Then participants are given the task to test memory, concentration, use of the words and reasoning, while two of these tests measures how easily they tend to make simple mistakes.
The tests are then repeated again when the participants are exposed to other factors such as bright light or allowed to take a nap. The result, in a test of memory, reasoning and concentration of participants who were given caffeine was better than placebo. This effect can be seen regardless of whether they drank a cup of coffee, energy drinks, caffeine pill, or eating foods containing high levels of caffeine. Although there is little difference in results between the participants who are given a cup of coffee compared with those allowed to nap, but a study showed that those who were given caffeine to make fewer mistakes.
"The results showed that compared with the intervention, caffeine can reduce the number of errors and improve cognitive performance in shift workers," said lead investigator, Katharine Ker from the London School of Tropical Medicine.
These findings have been published researchers in the Cochrane Library journal.
