Scientists Binghamton University in the US found that a lack of daylight can exacerbate the symptoms of obsessive-compulsive disorder (OCD). In particular, in high latitudes, where during the year, more cloudy days and less sunlight, the disease is more widespread. About it reported in a press release on EurekAlert!.

Obsessive compulsive disorder is a mental illness in which patients have Intrusive, disturbing or frightening thoughts (obsessions) that they try to get rid of the repetitive ritual actions (compulsive).

The researchers analyzed data on the prevalence of OCD in the various regions and find out in what latitudes the disease is most prevalent. According to scientists, in the Northern latitudes, less sunlight leads to misalignment of circadian rhythms and the circadian cycle that exacerbates the symptoms of OCD patients and increases the risk of development of disease in healthy people.

It is known that patients with OCD have difficulty falling asleep and sleep longer to compensate for the lost hours of sleep. Such delayed circadian rhythms exacerbate the disease. According to scientists, future research will help to develop methods for the treatment of OCD through normalization of sleep.
