A recent study has revealed that exposures to sun for short intervals of time may increase the risk of suicides. Over the span of months, it could help with suicidal tendencies.
Suicide is a complicated psychological condition and is affected by a number of external factors and does not depend on a single entity. Suicide could be provoked by any number of reasons. It could be the weather, social factors as well as biological factors. Sunshine could one such factor which can add to the suicidal tendencies.
Suicide is an attempt by the person to attract attention, a desperate attempt for help and support. The links between weather and the suicide tendencies have been studied for centuries. Researchers are aware of the effects of sunlight on suicidal tendencies but they are not sure of how it acts as a catalyst for such thoughts.
According to the study, there is a peak in suicide rates in the spring time. The suicide rates fluctuate greatly when there are temperature changes especially during holidays and festive season.
The study was based upon data from 69,462 suicides in Austria in between January 1970 and May 2010.The data was then matched with data from 86 area weather stations. The data included records of the hours of sunshine each day. The study revealed a clear link between the suicide rates and the hours of sunlight per day.
The study found that if there was 10 days or less of sunshine, people were more likely to commit suicide. If the sunshine varied between 14 and 60 days people were less liable to have suicidal thoughts. Sunlight affects the levels of serotonin in the body. Serotonin has an impact on mood, aggression, impulsivity. Light has an effect on serotonin and serotonin has an effect on mood and suicidal thoughts.
Because of these variations, researchers cannot say definitively whether sunlight causes or prevents suicide.
