according to National Institute of Neurological Disorders and Stroke In the United States, getting enough rest helps you focus better the next day and be more alert because, in addition to consolidating memories, it helps the brain form new neural connections.

pink noise

You may have heard about white noise before, white noisebut you still don’t know that of all the frequencies we can hear while we sleep, a little pink noise is also needed, pink noise. These are low-frequency sounds that are more powerful than white noise, according to a study published in 2017 on Frontiers in human neuroscienceStimulate our minds. According to the same study, when listening to pink noise, deep slow-wave sleep improves with positive effects on memory and brain performance.

Most people won’t notice much difference between white noise, pink noise, and brown, brown, or red noise. The only thing to be aware of is that pink noise has a “hissing” sound, brown noise has a “deep and quiet” sound, while white noise is somewhere in between.” healthy doctor Michael Grandner, director of the Sleep and Health Research Program at the University of Arizona in Tucson. “Pink noise has the ability to induce certain patterns of brain waves that improve sleep.”


The sense of smell is very powerful, and as we’ve been taught by talented writers and psychologists, it can bring back memories and evoke important feelings and moments in our lives. Feeling the right smell while sleeping makes a big difference.

In a study published in to knowTwo groups of volunteers played a memory game while the room smelled of roses.

The benefits are evident not only shortly before we abandon ourselves to Morpheus, but also a few hours before.

Avoid the midnight snack

2015 study, published in Neurology, lets us know that nighttime snacks affect circadian rhythms and the hippocampus, the part of the brain responsible for memory. The study even went so far as to show that if you’re hungry in the middle of the night, it could be a sign that you should have gone to bed earlier.
