Although most people think that sleeping is a loss of time, recent research shows that it is not exactly so. New scientific research proves that our memory strengthens while we sleep.
Researches tested a group of people. They showed them 50 objects on a computer, and the participants had to remember the exact location of each object.
In order to improve their memory, the showing of each object was accompanied by a sound. Later, while the participants were sleeping, the researches played half of the sounds.
The results showed that participants remembered the location of those objects which sounds they heard while they were sleeping.
But the author of the study warns that people shouldn’t expect to learn new skills or languages only by listening to sounds during sleep.
Sleep only reinforces the existing memory.
