Abstract
Gładka et al. [1], in their careful review of the literature,
gave indications of how air pollution can influence the
suicide rate. We must remember, however, that air pollution and global warming are both consequences of climate
change and are deeply associated [2].
There is strong evidence that high ambient temperature
is associated with the suicide risk, and increased morbidity and mortality among people with known mental health
problems [3]. Many studies have highlighted the close relationships existing between heat waves and mental disorders, such as psychological exhaustion, anxiety, mood disorders, and dementia, as well as the association of extreme
heat exposures with aggressive behaviors [4].
Our understanding of the combined effects of heat and air
pollution on mental health and suicide is still limited [5].
Among other things, the increase in temperature accelerates metabolism, and this could increase the toxic effect
of environmental pollutants. At present, we cannot say
whether the association between the 2 factors is additive
or multiplicative.
Ultimately, we agree with Gładka et al. [1] that further
research is needed to explore depression morbidity and
suicide statistics. The comparison of geographical areas
with high average concentrations of pollutants to those
with low pollutants may be useful, but research should
not neglect the confounding role played by heat wave.
An epidemiological approach based on large population
surveys, and the increasing availability of environmental
and public health databases across the world [6], could be
useful in gaining a better understanding of these complex
relationships.
