A group of scientists studied data from a sleep-tracking accelerometer. As a result, they figured out exactly how mental illness is associated with insomnia.
It turned out that the connection is very direct – such diseases lead to sleep disturbances in humans, writes PLoS Medicine. At the same time, insomnia can be both a factor and a symptom of the development of mental illness.
In order to come to this conclusion, experts analyzed the data of more than 89 thousand people who wore the accelerometer daily for several years. With its help, scientists collected information about the quality, quantity and other parameters of sleep.
It is worth noting that the greatest connection was found between sleep quality and severe depressive disorders. At the same time, according to scientists, insomnia is characteristic of all known disorders.
