Geophysical Variables and Behavior: LXXXXIX. The Influence of Weather on Suicide in Hong Kong

Abstract

Summer peaks in suicide for both sexes and ages groups (> or = 55 years) in Hong Kong were ascertained. Barometric pressure had a very weak negative relation with suicide rate.

Hypothetical Analysis of the Effects of Climate Change on Mental Health of Undergraduates in Alex-Ekwueme Federal University, Ebonyi State of Nigeria

“…On the other hand, a negative correlation was found by (Robbins et al, 1972;Rotton, 1986;Souetre et al, 1990;Lester, 1999). However, the positive relationship between temperature rise and suicide was reported by other studies (Yan, 2000, Page et al, 2007Yang et al, 2011;Likhvar et al, 2011;Muller et al, 2011). The results of the present study were not far-fetched as it recorded both positive and negative relationships as the case may be.…”

Weather and suicide: the present state of knowledge on the association of meteorological factors with suicidal behaviour

“…In those which did the findings were contradictory. For example, temperature which was the most frequently assessed variable in the studies reviewed was positively associated with suicidal acts in a number of studies (55, 61, 63–65, 68–70, 72, 74) but negatively in others (66, 72, 73, 75). Similar findings were reported for humidity, precipitation and sunshine duration while potentially important factors such as thunderstorms were investigated only in a small number of studies.…”

“…If any, rather an opposite trend might be suggested. At least as many studies found a higher incidence of suicidal acts on days with higher temperatures and/or more hours of sunshine or during periods or in regions with warm and sunny weather (53, 57, 58, 64, 65, 68–70, 74) as the contrary (56, 61, 66, 73, 75, 76). This finding is a further confirmation of the fact that the emergence of suicidality in a particular person is a phenomenon profoundly distinct from the so‐called normal, generally understandable reactions to environmental influences but is the consequence of an individual psychopathological process that is subject to an interaction of exogenous and endogenous factors.…”

“…Barometric pressure also correlates with impulsive behaviors [ 105 ], including suicide [ 106 , 107 ]. Although the association is statistically small, it remains significant.…”
