Europe faces severe health risks as heat wave strains cardiovascular systems and vulnerable groups

Record‑high temperatures across Europe are placing extraordinary strain on the cardiovascular system. Experts note that temperatures above 30 °C cause blood‑vessel dilation, lower blood pressure and increased heart‑pump workload, raising the risk of heart attacks, arrhythmias and circulatory collapse, especially for older adults, pregnant women, people with pre‑existing conditions and those on blood‑pressure medication.

German hospitals report a noticeable rise in emergency visits for heat‑related complaints, with some intensive‑care units treating patients whose body temperature reaches 41 °C, a condition that can lead to multiorgan failure. Physicians urge rapid cooling, fluid intake of 2–3 L per day and avoidance of strenuous activity during peak heat hours. The Swiss Blue Cross advises abstaining from alcohol during heat waves, citing dehydration and increased cardiovascular load. French authorities have even imposed temporary public‑space alcohol bans in the hottest regions.

Municipalities are deploying cooling strategies: Germany and other countries provide online maps of cooler public places such as parks, libraries, museums and shopping centres; some cities are testing moss‑covered façades that can lower surrounding air temperature by about six degrees Celsius. Public‑health campaigns stress regular checking on elderly neighbors, keeping indoor spaces ventilated at night, wearing light clothing and staying hydrated with water rather than sugary or alcoholic drinks. These coordinated measures aim to reduce the growing number of heat‑induced medical emergencies across the continent.
