we are able to hear and understand words while sleeping

We still have a lot to learn about sleep. Two studies which have just been published confirm this. The first, published Thursday October 12, tells us that we are not that disconnected from the world when we sleep. Researchers from Inserm and the Brain Institute in Paris subjected around forty volunteers to a vocabulary test as they fell asleep. While they slept, a recorded voice dictated a word to them. If the word existed, participants had to smile and when the word was invented, for example Dizza, or place of Pizza,
they had to frown. The surprise is that a good number of volunteers, with or without a sleep disorder, reacted to the test and made facial expressions while sleeping, which shows that even during sleep, there is a connection with the outside world.

Scientists want to continue research to find out if these windows opening onto the outside can be exploited to better understand and improve certain sleep disorders, such as nightmares or sleepwalking. The objective is also to know if it is possible to promote certain learning, because we know that the brain consolidates knowledge at night.

Improving the quality of your sleep is good for your health

In addition, if we already knew that lack of sleep could lead to an increased risk of cardiovascular disorders, a new study from Inserm, published Friday October 20, shows that it is not just the duration of sleep that matters.
Nearly 60% of cardiovascular accidents could potentially be avoided by taking care of the five essential sleep criteria: Guarantee seven to eight hours of sleep per night, be more of a morning person, fight against insomnia, avoid dozing during the day, do not suffer from sleep apnea or treat it. Each of the boxes checked already reduces part of the risk whatever the age. So it’s never too late to improve your sleep.
