Memory and sleep

Memory and sleep

Nowadays, our days are increasingly full. Between work and our various activities, we live a lot of new experiences every day. This means that a lot of information is stored in a single day. To be able to process all this data, sleep plays a crucial role. Au Bon Repos looks at the impact of sleep on memory.


During our sleep, all new information is analysed and stored in our memory. To be able to process this data, we must therefore respect our sleep time and the different phases of sleep. In fact, each phase strengthens a specific type of memory. To find out more about the different phases of sleep, you can read our article on this topic here.

So, although we sleep, our brain is still very active. In fact, it has been proven that during the night, the neuronal circuits that were used during the day are reactivated to process information and consolidate learning. A lack of sleep can therefore prevent the connections from being made and thus impact on memory. To compensate for this phenomenon, a nap is essential as it allows the necessary capacities to be revitalized.

Sleeping "on it”

You have probably already heard the famous saying "Sleep on it, you'll see more clearly tomorrow" and it is true. During our sleep, the brain does indeed store a lot of data. However, paradoxically, it also discards a lot of it. During the night, a real qualitative and quantitative sorting operation takes place to keep only the essential. After a good night's sleep, we generally see things more clearly, because our brain is then rid of the excess. A lack of sleep can therefore lead to the storage of junk data, which results in a reduction in the space available, or even saturation, for the 'real' information.

No memory without learning

To be able to memorize all the information accumulated during the day, the brain must first be prepared to receive such a large quantity of information, it must be prepared to learn. To learn optimally, sleep, again, has a crucial function. The quality of sleep can therefore create a virtuous circle or, on the contrary, a vicious circle since learning and memory are intrinsically linked.

Ideally, you need a good night's sleep to be able to learn well the next day, and then you need to sleep well again to be able to memorize this new knowledge. Be careful, however, not to confuse the memory and learning phases. Although the brain does indeed memorize information during the night, it is not possible to learn while sleeping because the brain is only slightly or not at all receptive to our environment when we sleep.
