Content: According to Bridges, recent research from industrialized countries (including Finland, Sweden, Australia, New Zealand, England, and Wales) has provided enough information to show a decrease in seasonal effects on suicide rates over the past few decades. In the case of Greece, seasonal variations in mortality from suicide are "more frequent during the spring and summer months…but [have] no regular annual rhythm". The Greek researchers proposed that "the seasonal variation of suicide follows more closely to the seasonal variation of sunshine, rather than the corresponding variation of temperature". Few scientific assessments have focused on seasonal suicide Epidemiology of suicide variations in the southern hemisphere. Studies in Brazil have shown that "the peak number of suicides occurred in spring (November) in men and women of Rio Grande do Sul state and in men of Paraná and Santa Catarina states, and in early summer (January) for women of Paraná state." One international study on seasonal effects on suicide rates involving 20 countries showed an early summer peak in suicides. She concluded that "seasonal variation in suicide incidence could be explained by the increase in sunshine in summer months because of a relationship between sunshine, high temperatures, and suicide rate". Australian researchers found a "spring peak in the number of suicides committed in Brisbane, Australia, but the results were not statistically significant…and that Dublin reported the incidence of suicide varied according to seasons in the northern hemisphere". French sociologist Émile Durkheim had found similar results, reporting that more suicides occurred in the spring than in the summer. Rather than emphasizing the role of nature, Durkheim interpreted the seasonal variation in sociological terms;
