“…These findings confirm the results of previous studies, which found a positive association between ED psychiatric visits and temperature, 33,[36][37][38][39][40] while only partially overlap with studies that observed an impact of heat waves (high temperature and humidity) on ED psychiatric visits. [37][38][39] A possible explanation of this discrepancy could lie in the different study design.…”

“…Nevertheless, only a limited number of studies has focused on the relationship between seasonality and ED visits for psychiatric emergencies, [33][34][35] or has been specifically designed to explore the association with meteorological variables. [36][37][38][39][40] Therefore, the aim of this study was to investigate the association between the rate of ED visits for psychiatric emergencies and variations of air temperature or humidity assessed on a daily basis.…”

Several disorders, such as renal colics, stroke, atrial fibrillation and others, are epidemiologically associated with seasonality and microclimatic variations. Although evidence is still limited, an association between psychiatric emergencies and seasonality has also been previously described. In order to elucidate the possible association between weather and incidence of psychiatric emergencies in a country with temperate climate, we analyzed the influence of day by day climate changes on the number of visits for psychiatric emergencies in an urban emergency department (ED) of northern Italy. All ED visits for psychiatric emergencies were retrieved from the hospital database from 2002 to 2010. The total number of ED visits was 725,812 throughout the study period, 11,786 of which for emergency psychiatric problems. We found a strong seasonal distribution of emergency psychiatric visits, peaking in summer and at the beginning of spring. The linear regression analysis showed a strong positive association between number of daily emergency psychiatric visits and mean daily air temperature (R=0.82; P<0.001), and an inverse association with mean daily air humidity (R=-0.52; P<0.001). These findings suggest that psychiatric disorders follow a significant seasonal variation, so that it may be advisable to strengthen psychiatric emergency services during the hottest months.

“…Results of the multiple regression did not show any significant relationships between climate indicators and the rate of mental health service utilization (Table 3) as some of the studies earlier cited in this paper [3][4][5][6][7] suggested, but in agreement with [8]. The results derived from this study suggest that high temperatures do not necessarily correlate with an increased utilization of mental health services.…”

“…The traditional factors that account for low mental health service utilization-such as one's low perception of the need for services, lack of insurance, prohibitive cost of treatment, stigma, or even the perception that treatment would not help-may partially explain why a linear and strong correlation was not shown [16]. In addition, the regression analysis did not account for the lag time effect of high temperatures in service utilization rates, which was observed in [5]. This may have provided important insights on the gestation period when the interaction between high temperature and one's emotional and behavioral well-being leads an individual to seek treatment.…”

“…However, the impacts of temperature on behavioral health (substance abuse and mental health) have not received as much attention as those on physical health. A number of Australian and Canadian studies indicate that rising temperatures can also lead to exacerbation of behavioral health issues, causing increases in, for example, emergency room visits due to mental health [4,5]. Researchers have begun to develop a framework to understand the relationship between temperature and mental health [6].…”

Climatic variables such as temperature have been shown to correlate with demand for mental health services in other countries. An attempt by the present study to replicate this correlation using existing USA treatment data on mental health was not substantiated. Using annual state-level data from 2007 through 2015, the rate of mental health service utilization per 1000 population was correlated with average temperature and precipitation, while adjusting for Gross Domestic Product (GDP), unemployment, and urbanization. No statistically significant correlation was found.
