Scientists from Monash University in Australia found that too much artificial light at night can trigger the development of depression, PTSD, bipolar disorder and increase anxiety. Most likely this happens due to disruption of human biorhythms associated with the change of day and night. In this respect reports MedicalXpess.
The research team analyzed data from 86,772 individuals from the UK Biobank. A biobank is a repository of biological samples (usually human) for use in research. Researchers evaluated the subjects’ sleep quality, day and night light exposure, activity levels and mental health.
People who were regularly exposed to bright artificial light at night were found to have a 30% higher risk of depression, bipolar disorder, psychosis, post-traumatic stress disorder and anxiety disorder. At the same time, people who got plenty of natural daylight were 20% less likely to develop these diseases.
Artificial light can come from phone and computer screens and be used to light streets. Researchers believe that the need to use constant lighting at night is increasing due to the increasing number of people living in cities and the industrialization of society. This leads to disruptions in human biorhythms, which include being awake in bright light and sleeping in the dark. Such interruptions can have a negative impact on the psyche and lead to the emergence of various diseases.
The authors recommend maximizing natural light during work hours to reduce the risk of mental health problems and increase productivity. If you have to work at night, you practically have to do it in the dark.
