Sunlight increases the risk of suicide?

For a long time, exposure to darkness for a long time is thought to be related to depression. However, a new study suggests that high-intensity sunlight exposure, at least in the short term, is a factor associated with higher suicide rates.

In the paper published in the JAMA Journal of Psychology, the team of scientists at the University of Vienna conducted a study on the relationship between daylight exposure time and suicide rate in Austria in the period from January 1970 to May 2010.

During a fierce sunny day, the suicide rate tends to increase markedly.

Accordingly, the time for sunlight is calculated from 86 meteorological stations. At the same time, experts also looked at more than 69,000 suicides over the 40-year period of the study.

The results show that exposure time to sunlight and the number of suicides are closely related. Especially in a fierce sunny day, suicide rate tends to increase markedly.

Scientists believe that exposure to high-intensity sunlight in the short term (less than 10 days) seems to be a suicide boosting factor. However, when exposed to sunlight lasts from 14-60, this ratio decreases.

The scientists also found a close association between women's suicide rates and the time they were exposed to sunlight. While for men, after exposure to sunlight for a long time, the rate of suicide decreased markedly.

When the cause of this condition has not been found, it is suggested that light can interact with serotonin, neurotransmitters in humans and animals that can affect mood.

This means that exposure to sunlight can alter serotonin levels, leading to inconsistent behavior and emotions in humans or animals.
