Depression Caused By Overexposure To Light

City lights are always on and improve civilians’ visibility and security. Current study though, conducted through the Ohio State University, revealed that exposure to constant lumination disrupts circadian rhythm and can cause adverse psychological outcomes, among which despression symptoms. The human circadian system works based on a 24-hour light-dark pattern that mimics the earth’s organic light/dark rotation. When the circadian clock is disrupted, several physiological processes – including brain wave patterns and hormone levels- are impacted.

Depression Caused By Overexposure To Light

The research workers attribute the higher amounts of despression symptoms in contemporary societies to the improve of artificial light at night. It’s common for individuals who live by over-illuminated streets to complain for sleeping difficulties and bad mood. It isn’t the first time that artificial lumination is a suspect for health issues. It has been into focus for various types of cancer, seasonal affective disorder, and delayed sleep phase syndrome.

The new study, which was based on mice tests, confirmed that people who lived under lumination 24 hours a day showed more signs of depression that those who lived within the regular light dark cycle. The mice that had been given the opportunity to escape from constant light and move to some dim corner had much much less despression symptoms signs and symptoms. The research workers point out that people functioning in night shifts, kids who watch TV till late at night and patients within the hospitals, especially those within the intensive care units may be impacted from more than exposure to lumination. And they underline the need for much more studies within the field.
