This work analyses three uncertainty sources affecting the observation-based gridded data
sets: station density, interpolation methodology and spatial resolution. For this purpose, we …

Background Temperature change between neighboring days (TCN), an indicator to reflect
sudden temperature variation, has been identified as an independent risk factor for human …

Background Previous studies have found high temperatures increase the risk of mortality in
summer. However, little is known about whether a sharp decrease or increase in …

In this study we evaluated the association between temperature variation and mortality and
compared it with the contribution due to mean daily temperature in 6 cities with different …

Background Many studies have shown that high temperatures or heat waves were
associated with mortality and morbidity. However, few studies have examined whether …

Background Climate change, as a defining issue of the current time, is causing severe heat-
related illness in the context of extremely hot weather conditions. In Japan, the remarkable …

The health impact of climate change depends on various conditions at any given time and
place, as well as on the person. Temporal variations in the relationship between high …

(1) Background: So far, research results have confirmed the relationship between heat and
cold stress, the fluctuations in atmospheric pressure and high relative humidity, and the …

Background Although the impacts of temperature on mortality and morbidity have been
documented, few studies have investigated whether day-to-day temperature change and …

Numerous reports document advances made in our understanding of the effects of negative
air ions on physiological functions and human health. Collectively, these reports …
