Sharjah 24 – WAM: Portugal’s health authorities have reported 1,331 excess deaths between 27 July and 15 August, attributed to extreme heat, particularly affecting the elderly, according to Euronews.

Prolonged heat alerts and rising mortality

The months of July and August saw several heat warnings across the country. According to data from the Death Certificates Information System (SICO), there were 20 consecutive days of excess mortality, representing a 25% increase in deaths during this period.

Older adults hit hardest by the heat

The 75+ age group was most impacted due to increased vulnerability. Of the 34 days with excess mortality in July and August, 29 days showed a spike in deaths among those over 70.

Regional impact across the country

The Directorate-General for Health (DGS) stated that while excess deaths occurred nationwide, northern, central, and Alentejo regions were especially affected.

Health risks worsened by heat

Authorities cited dehydration and exacerbation of chronic conditions, especially cardiovascular and respiratory diseases, as key factors in the spike in deaths among vulnerable populations.

July's heatwaves were critical

The month of July was especially severe, with two significant heat spells from 1–9 July and 25–31 July, contributing substantially to the overall excess mortality.
