    A study published in the journal Psychological Science says that sleeping during study can make it easier to recall what you've learned and even recall things you've forgotten for six months.
    Stephanie Mazza, a psychologist at the University of Lyon, said: "Our results suggest that alternating sleep during practice can be twice as effective, reduce the amount of time spent on re-learning, and maintain longer-term memory.
    past studies have shown that sleeping after study helps with learning.
    now we find that sleeping in the middle of learning works better.
    " Although studies have shown that both repetitive exercises and sleep can help improve memory, few studies have focused on how the combination of repetition and sleep affects memory.
    Mazza and colleagues speculate that sleeping during study can make the relearning process more efficient and reduce the effort required to keep information in memory.
    the study, 40 French adults were randomly assigned to the "sleep" and "wake up" groups.
    the first stage, all subjects were presented with 16 pairs of randomly sequenced French and Swahili word pairs.
    after seven seconds of study, only the Swahili word remained, and the subjects chose French translation.
    correct result after 4 seconds.
    words that have not been correctly translated will reappear until each word is correctly translated.
    12 hours after the first phase of study, the subjects completed the task again until all 16 words were translated correctly.
    Importantly, some of the subjects completed the first phase of the task in the morning and the second phase in the evening (the "wake-up" group), while others completed the first phase of the task in the evening, then went to bed, woke up in the morning and completed the second phase of the task (the "sleep" group).
    in the first phase, the two groups learned almost the same way.
    12 hours, the results were different: participants in the Sleep group remembered an average of 10 words, while those in the "wake up" group remembered 7.5 words.
    when they repeated their studies, people in the "sleep" group needed only three times to recall 16 words, while those in the "wake up" group needed six times.
    , both groups remembered 16 words, but sleep seemed to take less time for the subjects.
    memory that you can't get at the beginning of re-learning seems to have been changed in some way by sleep, " says Mazza.
    this change allows the subject to encode information more quickly, saving time in the re-learning process.
    " subjects seemed to get a long period of memory improvement from sleep during their studies.
    the next data showed that people in the "sleep" group still performed better after a week.
    the "sleep" group forgot less, they remembered 15 words, while those in the "wake up" group remembered only 11.
    six months later, the effect is still evident.
    the benefits of sleep in this study could not be attributed to differences in the quality of sleep and their long- or short-term memory, as there was no difference in these measurements between the two groups.
    Mazza concluded: "The results of this study suggest that alternating sleep during learning can easily and effectively improve the ability to remember information over the long term.
