Next time you want to remember your lessons, just sleep it off, say scientists. A good night's sleep can do wonders especially to retrieve memory or to boost the ability to learn language, according to recent research.
Scientists say that sleep has tremendous effect on learning- it helps to recover and restore memories, according to them. Sleep rescues memories that had began to deteriorate the previous day.
In a set of experiments, some students underwent training, followed by a test. 54 per cent of students did well, in the test conducted one hour after the training. In another group, students were trained in the morning and tested 12 hours later. Only 10 percent did well. But students trained in the evening and tested the following morning, after a night's sleep, improved their performance by 19 percent. Further testing revealed that students trained in the evening performed just as well 24 hours later as people trained in the morning did. Since they went to bed shortly after training, those in the evening group didn't exhibit the temporary performance declines observed in the morning group.
Scientists explain that knowledge gained during training takes a dip immediately afterward. A good night's sleep then revives much of what was forgotten. While the benefits of sleep are well known, this research has shown that while we sleep, brain activity encourages higher types of learning.
