Abstract:
Much evidence shows that meteorological factors are closely related to human health. By combining relevant domestic and foreign literature, this review found that there were currently many studies on the association between meteorological factors such as air temperature, sunshine duration, and relative humidity and suicide. Some studies have found that they are related to suicide, while others have not found such an association. There are relatively fewer studies on the association between other meteorological factors and suicide. The mechanisms for the association between air temperature and suicide include physiological and biochemical mechanisms, behavior and lifestyle mechanisms, brown adipose tissue theory, and psychological mechanisms. There is a lack of research on the mechanisms for the association between other meteorological factors and suicide. In the future, it is necessary to strengthen the research on the association between meteorological factors and suicide to clarify their causal relationship and mechanisms to provide a scientific basis for reducing suicides related to climate change.
