Cardiovascular disease (CVD) follows a seasonal pattern in many populations. Broadly
defined winter peaks and clusters of all subtypes of CVD after'cold snaps' are consistently …

Objective To assess the seasonality of cardiovascular risk factors (CVRF) in a large set of
population-based studies. Methods Cross-sectional data from 24 population-based studies …

Coronary heart disease exhibits a winter peak and summer trough in incidence and
mortality, in countries both north and south of the equator. In England and Wales, the winter …

Classical risk factors only partially account for variations in cardiovascular disease
incidence; therefore, also other so far unknown features, among which meteorological …

The circadian system, that is ubiquitous across species, generates∼ 24 h rhythms in
virtually all biological processes, and allows them to anticipate and adapt to the 24 h …

Essentially all biological processes fluctuate over the course of the day, observed at cellular
(eg, transcription, translation, and signaling), organ (eg, contractility and metabolism), and …

A growing number of extreme climate events are occurring in the setting of ongoing climate
change, with an increase in both the intensity and frequency. It has been shown that ambient …

Seasonality in disease was first recognised by Hippocrates (460–370 BC) who said,“All
diseases occur at all seasons of the year, but certain of them are more apt to occur and be …

Objective To examine possible seasonal changes in heart rate variability (HRV).
Background Greater than normal mortality from cardiovascular disease (CVD) in the winter …

All species organize behaviors to optimally match daily changes in the environment, leading
to pronounced activity/rest cycles that track the light/dark cycle. Endogenous, approximately …
