Poor sleep affects the relationship between the spouses. If suddenly there is a misunderstanding in the family, the reason may lie in sleep disorders. This was stated by scientists at the University of California, Berkeley (USA). According to the study, in which more than 60 couples of the ages between 18 and 56 years participated, sleep disorders can lead to the fact that a partner in a couple ceases to be thankful for the things that seem to him for granted.

According to RIA Novosti, the study was conducted in two phases. During one of them the participants kept a diary of their sleep, noting how good or bad their sleep affects the perception of their partner. In the second phase the volunteers were recorded on video when challenging tasks. As a result, those who slept badly the night before the experiment, showed less satisfaction with their partner.

The only way out, according to scientists, is to express gratitude to each other for little things more often.
