Scientists from the University of Massachusetts Amherst (USA) have denied a popular misconception about the healing power of sleep.
They showed 106 participants aged 18-30 years to 30 photos with neutral content and harrowing images (for example, the horrors of war) and asked to rate their emotional distress on a nine-point scale.Next, the researchers mixed the first photos from the new 120, and showed them again, but after 12 hours, asking you to specify which of them are familiar.

For this reason, the evening is not desirable to sort things out with someone or watching horror movies.
