BACKGROUND In the past three decades, Tehran has experienced warmer summer so we need to determine heat-related mortality to establish appropriate public health activities during hot summers. The aim of the present study was to detect heat waves during the last decades and then determine excess mortality in immediate and lagged times. METHODS An ecological study based on time-series model was...

Hot weather is an important determinant of human mortality. In the United States, a major heat wave can cause literally thousands of excess deaths in a given summer. Yet, for purposes of public health, the term "heat wave" is not easily defined. "Hot" is a relative term, and periods of hot weather (heat waves) vary greatly in intensity and duration. Ambient temperatures may change rapidly, and ...

Index words: Climate change Extreme heat Chicago Heat waves Health impacts Mortality Over the coming century, climate change is projected to increase both mean and extreme temperatures as heat waves become more frequent, intense, and long-lived. The city of Chicago has already experienced a number of severe heat waves, with a 1995 event estimated to be responsible for nearly 800 deaths. Here, f...

Studies conducted to evaluate temporal trends of heat-related mortality have not considered the effects of heat waves; although it is known they can affect mortality and act as a modifying factor. After adjusting for long-term trends and seasonality, the effects of temperature on non-accidental deaths in Seoul and Busan (inland and coastal cities, respectively) were analyzed using a generalized...

Observations and Impacts. Andhra Pradesh, Telangana, and other southeastern Indian states suffered a deadly heat wave in late May and early June of 2015. Daily high temperatures exceeded 45°C in many places throughout India for several days in a row. In late June and early July, just a few weeks later, Pakistan also suffered from a deadly heat wave with similar daily high temperatures. Although...

(1) Background: To demonstrate the potential effects of missing exposure data and model choice on public health conclusions concerning the impact of heat waves on heat-related morbidity. (2) Methods: Using four different methods to impute missing exposure data, four statistical models (case-crossover, time-series, zero-inflated, and truncated models) are compared. The methods are used to relate...

Heat waves that trigger severe droughts are predicted to increase globally; however, we lack an understanding of how trees respond to the combined change of extreme temperatures and water availability. Here, we studied the impacts of two consecutive heat waves as well as post-stress recovery in young Pseudotsuga menziesii (Mirb.) Franco (Douglas-fir) and Robinia pseudoacacia L. (black locust) g...
