Some new research from the University of York has explored why sleep is so important for our memory.

The results of the research, carried out at York's Sleep, Language and Memory Laboratory, were presented in the journal Cortex on 14th November. 

The researchers carried out an experiment with two groups of participants, testing their recall of the location of some words on a computer screen. One group slept for an hour and a half after the test, while the other group stayed awake.

The test was then repeated and the two groups showed differences in their recall. The group who had slept showed evidence that memory updating had taken place during sleep and overall, the researchers concluded that sleep has a positive effect on the strengthening of memory.
