Climate variations: Risk factor of commiting suicide

Abstract

Introduction. Recently there have been more and more attempts at getting into connection the frequency of suicide with climate factors, humidity changes, atmospheric pressure. A large number of authors agree that suicide has meteorological character and that weather can be a provoking factor in suicidal persons. Suicides happen most frequently when the weather is warm, stable, and sunny; then, when it is rainy, cloudy and with high humidity, and least frequently when the atmospheric pressure and temperature are decreased accompanied with wind. Climate variations and suicide. Men who commit suicide show a significant, positive connection with indicators of temperature and exposure to sun, and a significant, negative connection with indicators of humidity and rainfall. Women who commit suicide show a less significant connection with climate variations - indicators. Violent and non-violent suicide. Regarding violent and nonviolent suicide, it has been proved that violent suicide is affected by environmental temperature, sunny intervals, raise in temperature in the previous few weeks. Higher envi?ronmental temperature and increase in air temperature in the previous few weeks are the most significant climate factors influencing the violent suicide rate. In addition, each degree exceeding 18?C increases the violent suicide rate by 3.8-5%. Conclusion. The result of many investigations of the influence of climate factors on committing suicide is that the suicide incidence reaches its peak during early summer. Also, the sun radiation the day before suicidal event is significantly connected with the increased suicidal risk. There is a difference between sexes. If the sun were a trigger, men would have to be exposed to it for a longer time than women.
