“…These "thresholds" are about 17-18°C in Northern and Central Europe, 22-23°C in Southern Europe, 25°C on the Eastern Coast of the United States, and 26-29°C in Australia and South-East Asia. The adverse effects of increased temperatures can be prolonged for many days (so-called lagged effects) (Braga and Zanobetti 2002;Conti et al 2005;Curriero et al 2002;Davis et al 2003a;Davis et al 2003b;Dessai 2002;Donaldson et al 2001;Donaldson et al 2003;Gosling et al 2007;Gouveia et al 2003;Hajat et al 2005;Huynen et al 2001;Keatinge et al 2000;Michelozzi et al 2005;O'Neill et al 2003;Paldy et al 2005;Pattenden et al 2003;Sartor et al 1995;Vandentorren et al 2004). In addition, there is evidence suggesting that colder than normal temperatures can increase mortality (Carson et al 2001;Doyon et al 2008;Goodwin 2007;Gouveia et al 2003;Kovats et al 1998;Martens 1998;McMichael et al 2006), although these effects appear to be delayed for as many as two weeks into the future (Braga and Zanobetti 2002;Gouveia et al 2003;Huynen et al 2001;Pattenden et al 2003).…”

The association between short-term changes in ambient temperature and daily mortality has been described widely in the literature. A few recent papers support the hypothesis that diurnal variations in temperature may also have an impact on mortality, independent of the effect of daily mean temperature. The objective of the thesis was to determine whether variations in diurnal temperature increased daily non-accidental mortality among the elderly population of Montreal, Quebec, during the 1984-2007 study period. We used distributed lag non-linear models constrained over a 30 day lag period, and adjusted for temporal trends, mean daily temperature, and mean daily concentrations of nitrogen dioxide and ozone. We found over the 30 day lag period a cumulative increase of 5.12% (95% confidence interval (CI): 0.02 to 10.49) in daily mortality for an increase of the diurnal temperature range from 6 °C to 11 °C and a 11.27% (95% CI: 2.08 to 21.29) increase in mortality associated with an increase of the diurnal temperature range from 11 to 16 °C. The results were relatively robust to adjustment for mean temperature.In conclusion, we found that in Montreal daily diurnal variations in temperature are associated with a small increase in mortality among the elderly population. More studies are needed in different geographical locations to confirm these effects.ii Résumé L'association entre les variations à court terme de la température ambiante et la mortalité quotidienne a été largement décrite dans la littérature.

Studies in global warming and climate change indicate that human populations will be deleteriously affected in the future. Studies forecast that Australia will experience increasing heat waves and droughts. Heat stress caused by frequent heat waves will have a marked effect on older Australians due to physiological and pharmacological factors. In this paper we present an overview of some of the foreseeable issues which older Australians will face from a public health perspective.

“…As global warming continues, there is increasing evidence that extreme climatic events are becoming more frequent, more intense, and longer-lasting (Guo et al 2013;Gao et al 2015). Extreme heat events have increased human mortality in North America (IPCC 2014) and Europe (Conti et al 2005;Michelozzi et al 2009;Lass et al 2011;Schuster et al 2014). Cold weather also contributes to a wider range of impacts on public health, including death from respiratory and cardiovascular diseases (CVD) (Braga et al 2002;Barnett et al 2012).…”

Extreme temperature events have affected Chinese city residents more frequently and intensively since the early 2000s, but few studies have identified the impacts of extreme temperature on mortality in different city clusters of China. This study first used a distributed lag, nonlinear model to estimate the county/district-specific effects of extreme temperature on nonaccidental and cardiovascular mortality. The authors then applied a multivariate meta-analysis to pool the estimated effects in order to derive regional temperature-mortality relationship in three large city clusters-the Beijing-Tianjin-Hebei (BTH) region, the Yangtze River Delta (YRD), and the Pearl River Delta (PRD), which represent northern and southern regions. With 0-3 days' lag, the strongest heat-related mortality effect was observed in the BTH region (with relative risk (RR) of 1.29; 95% confidence interval (CI): 1.13-1.47), followed by the YRD (RR = 1.25; 95% CI: 1.13-1.35) and the PRD (RR = 1.14; 95% CI: 1.01-1.28) areas. With 0-21 days' lag, the cold effect was pronounced in all city clusters, with the highest extreme cold-related mortality risk found in the PRD area (RR = 2.27; 95% CI: 1.63-3.16), followed by the YRD area (RR = 1.85; 95% CI: 1.56-2.20) and BTH region (RR = 1.33; 95% CI: 0.96-1.83). People in the southern regions tended to be more vulnerable to cold stress, but the northern population was more sensitive to heat stress. By examining the effects of extreme temperature in city clusters of different regions, our findings underline the role of adaptation towards heat and cold, which has important implications for public health policy making and practice.
