Scientists from the United States have conducted interesting experiments on mice and have made an important conclusion about their sleep. It turned out that rodents show a certain tendency to sleep in the company, even if this dream can be less calm than the one that happens alone. Researchers suggest that animals are ready to sacrifice the quality of their sleep in exchange for physical contact. This discovery can be similar to people.
From an evolutionary point of view, sleep is regarded as a vulnerable condition that the brain can be delayed until it is convinced of the environment. Physical contact with a partner is considered as one of the means to convince the brain in safety, and this can happen in both animals and humans.
Previous studies also indicate the effect of physical proximity on the quality of sleep. In particular, it is established that women in happy marriages sleep better due to the stimulation of oxytocin, which promotes a sense of peace and relaxation.
According to new data from Michigan University, sleep alone can be more favorable to health than joint sleep with a partner. Observations in mice have shown that, despite the craving for physical contact at bedtime (somatolonia), rodents prefer sleep together. However, this has often led to each other's sleep disorders, similar problems that may occur in a common dream of people.
It is interesting that, even in the presence of these violations, in joint sleeping mice there was a synchronization in several neurophysiological indicators. This can make a significant contribution to our understanding of human sleep and the impact of physical contact on its quality.
