Do you want to improve your attention and memory? Use a sleep mask
Sleep masks are familiar to us mainly from foreign films. Their heroes often pull them on with a serious look while lying in bed. This strange accessory seems ridiculous and ridiculous to many. It is used here, except in trains and airplanes, to exclude light stimuli. But scientists have found out that sleeping in a mask is of higher quality and this affects a person's cognitive abilities.
An international team of scientists has seriously taken up the issue of sleep masks and made unexpected conclusions. Psychologists and somnologists from the universities of Cardiff (UK), Northwestern (USA) and Padua (Italy) said that the habit of using a mask can positively affect a person's life.
122 people who lead a healthy lifestyle and do not have serious diseases were selected to study the issue. During the first test, 89 participants aged 18 to 35 years slept with and without masks. At first they were asked to sleep in masks for about a week. Then they spent the same amount of time sleeping without them. In this part of the experiment, participants were tested for word pair associations. This is a popular way to test a person's cognitive functions all over the world.
The second experiment involved 33 people. They slept in masks and at the same time used devices to determine the intensity of light and measure brain activity. After that, they were also waiting for a test with pairs of words. Both experiences have shown that using a sleep mask helps to better recall old information and assimilate new ones. The mask also increases the slow sleep phase, which has a positive effect on improving memory.
The study participants recorded sleep parameters in questionnaires. From them, scientists learned that masks did not affect the duration of stay in the arms of Morpheus. They just made the rest more qualitative and useful for the human brain. So urgently get a sleep mask and get used to it. Perhaps it will help you reach new heights in your career, or simply simplify the solution of everyday tasks.
Sleep disorders are a real scourge of modern society. Hypersomnia, which many of us are familiar with, brings especially many problems.
