“…Heat disorder is a preventative illness, but still common 6,11,[16][17][18] . The deleterious effects of heat stress can be improved by acclimatization, work and rest cycle, fluid intake, and altering clothing and gaining access to air conditioning [16][17][18] . However, implementing strategies targeted to groups at risk has proved to be difficult 19) .…”

In the present study, a survey on subjective symptoms and hot prevention measures in summer was conducted in 204 male traffic control workers and 115 male construction workers. Work loads of traffic control workers and construction workers were estimated at RMR 1-2 and RMR 2-4, respectively. A self-administered questionnaire was used to collect information on age, occupational career, working habit, present or past history of diseases, individual preventive measures to the heat, and subjective symptoms in the summer. Daily working hours in the sunshine of the traffic control workers were significantly longer than those of the construction workers. Prevalence rates of changing clothes frequently, avoiding direct exposure of face and neck to sunlight using towel like materials, and wearing sunglasses in the traffic control workers were significantly lower than the construction workers. Prevalence rates of symptoms in the upper extremities in the traffic control workers were significantly lower than those in the construction workers. Prevalence of work difficulty due to hot weather during work in the traffic control workers was significantly lower than the construction workers. On the basis of the results obtained, some preventive countermeasures to improve working environment are presented.

“…Además de la mortalidad debida a golpe de calor, las enfermedades cardiovasculares, la obesidad excesiva, los enfermos tratados con neurolépticos y, en menor grado, algunas enfermedades respiratorias crónicas han sido también asociadas con un mayor riesgo de mortalidad en períodos de temperaturas elevadas 10,11 . Desde las primeras décadas del siglo XX el calor excesivo se ha asociado a la mortalidad 12 .…”

“…Además de la edad y el medio ambiente urbano, el bajo nivel socioeconómico es un factor de riesgo asociado con la mortalidad durante las olas de calor 14 . Asimismo, tener acceso al aire acondicionado en el domicilio o en algún otro lugar durante el día es un importante factor de protección 11,[15][16][17] . La relación observada entre las temperaturas extremas y la mortalidad sigue una forma de U o de J, con tasas de mortalidad menores a temperaturas alrededor de 20 °C 18,19 .…”

ResumenLas altas temperaturas experimentadas en Europa durante el verano de 2003 tuvieron un efecto en la mortalidad en varios países, incluido el nuestro. En este capítulo se describe la mortalidad registrada durante el período comprendido entre el 1 de junio al 31 de agosto de 2003, y se comenta el impacto de las olas de calor sufridas.El número de defunciones se obtuvo de los registros civiles de las capitales de provincia y de una muestra aleatoria de 107 municipios rurales. Esto se comparó con la mortalidad esperada, estimada mediante un modelo de regresión de Poisson sobre series históricas de defunciones, corregido por la tendencia ascendente y la estacionalidad de la mortalidad. La información meteorológica la proporcionó el Instituto Nacional de Meteorología.España experimentó tres períodos de temperaturas elevadas. El exceso de defunciones asociado fue del 8% (43.212 observadas por 40.046 esperadas). El exceso de mortalidad afectó exclusivamente a las personas mayores de 65 años (15%). Este incremento también se observó en el medio rural.Este fenómeno es un problema de salud pública emergente por su riesgo atribuible creciente debido al envejecimiento de la población. Frente a ello, se pueden plantear sistemas de alerta y respuesta basados en el control de riesgos naturales, las demandas médicas de urgencia y las defunciones, así como en el fortalecimiento de la capacidad de respuesta de los servicios sociales y sanitarios. Palabras clave: Calor/efectos adversos. Humanos. España/epidemiología. Europa/epidemiología. Factores meteorológicos. Mortalidad. Estaciones. AbstractThe effect of the elevated temperatures experimented in Europe during the summer 2003 on mortality was observed in several countries. This study, carried out in Spain, describes the mortality between the 1 st June and the 31 st August and evaluates the effect of the heat wave on mortality.Observed deaths were obtained from official vital Registers of the capital city of the 50 provinces. Deaths from 107 randomly selected rural villages were also obtained from the same source. Observed deaths were compared with expected estimated applying a Poisson regression model to historical mortality series adjusting for the upwards trend and seasonality observed. Meteorological information was provided by the National Institute of Meteorology.Spain experienced three heat waves. Total excess deaths associated was 8% (43212 observed compared with 40046 expected). Excess deaths were only observed among 65 years old and over (15%). The increased mortality was also observed in rural villages.This phenomenon is becoming an emerging public health problem because of its increasing attributable risk because of the aging of Spanish population. Alert and response systems based on monitoring of climate related risks, emergency rooms activity and mortality and the strengthening of social and health services response capacity should be considered.

“…There is also some evidence that the presence of vegetation and shade trees in the vicinity of the home may create a cooling effect that can reduce heat-related health impacts [62,63]. Yet an Australian study on heat-related deaths in Sydney found there was no significant contribution from the proportion of vegetation [43].…”

Urban Green Infrastructure Impacts on Climate Regulation Services in Sydney, Australia

et al. 2016

Abstract:In many parts of the world, urban planning has a renewed focus on addressing the multiple challenges associated with population growth and climate change. Focused on local needs and priorities, these planning processes are raising tensions between more compact and dense urban form to reduce energy use and associated emissions and the provision of urban green infrastructure for ecosystem services and climate adaptation. In this study, we investigated the spatial distribution of green infrastructure at the neighbourhood scale in Sydney, Australia and examined how a mix of landscape types (pavement, bare soil/dry grass, green grass, and tree cover) affect temperature variation in three important locations for urban residents-around the home, in the roads and footpaths where people walk, and in parkland areas. Considering that residential and parkland areas contribute to the majority of green space in Sydney, it is important to understand how changes in landscape mix within these three neighbourhood areas will affect local temperature for urban residents. For residential houses, it was found that the percentage of tree canopy cover around the house had a significant negative relationship (p = 0.002) with surface temperatures of rooftops where greater tree cover led to lower rooftop temperatures. In streetscapes, both the percentage of tree cover (p < 0.0001) and the percentage of green grass (p < 0.0001) within the road segment had a significant negative relationship with the surface temperature of the road pavement. In the parks, the percentage of pavement (p < 0.0001) and the percentage of bare soil/dry grass (p < 0.0001) showed a significantly positive trend with land surface temperatures where greater land cover in the form of pavement and bare soil/dry grass led to higher temperatures. Collectively, these findings highlight the importance of promoting or reducing certain landscape covers depending on the land use type in order to maximise the cooling potential of green infrastructure.
