The relationship between cardiovascular health and climatic conditions is a central issue of cardiological research in order to face the global warming challenge. This article analyses 15 locations in rural Spain between 1920 and 1950. The main objective is to know how temperature affected mortality due to cardiovascular causes in a historical context. Based on historical data on the cause of death, age, sex, time of death and temperature, an analysis has been carried out using descriptive statistics and MLS regressions to determine the effects of extreme temperatures on cardiovascular health. The results evidence that mortality from cardiovascular causes was concentrated on the coldest and hottest days of the year, and on subsequent days, being especially important in the case of deaths from ischemic heart disease. There is a pattern of summer-winter differentiated mortality depending on the hottest and coldest hours of the day. [ABSTRACT FROM AUTHOR]

This article analyses the evolution of the weekly distribution of weddings, over about 250 years, in the municipality of Fafe, located in the north of Portugal, based on a sample of microdata made up of 26,841 wedding dates that allow to observe the weekly pattern of weddings in the municipality of Minho, establishing a relation to the differential indicators: demographic and socioeconomic behaviours of the bride and groom, between 1650 and 1905. The results showed trends according to the characteristics of the bride and the groom. Over more than two centuries, there was a predominance of Sunday and Monday acts. However, these results do not cover all individuals since premarital conceptions and socio-professional indicators influenced the choice of the wedding day. [ABSTRACT FROM AUTHOR]
