Extreme Heat Wave in May 2026 Endangers the Health of Elderly People in Romania

May 2026 has become the hottest month in the history of meteorological records, with temperatures exceeding the norm by up to 16 degrees Celsius across many regions of Europe. This phenomenon, known as a "heat dome", poses a serious threat to the health of elderly people.

In Romania, the previous record of 29.1°C for the month of May was shattered, with temperatures reaching 33.3°C. This extreme weather situation places enormous strain on the bodies of older adults, who are more vulnerable to heat shock and dehydration.

What is a heat dome and how does it affect older people

A heat dome forms when a powerful high-pressure system establishes itself and stagnates over a region. This "thermal cap" pushes warm air downwards, prevents cloud formation and blocks cold air from moving in. For elderly people, whose thermoregulatory systems are less efficient, these conditions can become extremely dangerous.

Extreme heat can cause rapid dehydration, hyperthermia, and can worsen chronic conditions such as cardiovascular disease, diabetes, or respiratory problems — all of which are common amongst older adults.

Documented risks for elderly people

Data from 2025 illustrates the scale of the danger: in Romania, Bulgaria, Greece and Cyprus, a single heatwave in July caused approximately 950 deaths associated with extreme temperatures, equivalent to around 11 deaths per day per million inhabitants. The vast majority of victims were elderly people.

Meteorologists warn that the European summer is not only becoming hotter, but is also extending at both ends. What was previously considered a typical July phenomenon is now occurring in mid-May, reducing the time the body has to adapt to high temperatures.

Protective measures for older adults

In the face of this new climatic reality, it is essential that elderly people and their carers take preventive measures: staying consistently hydrated, avoiding sun exposure during peak hours, using air conditioning units or ensuring adequate ventilation, and carefully monitoring their state of health.

Care homes and home care services must adapt their protocols to cope with these increasingly frequent extreme weather conditions. Investment in cooling systems and staff training to recognise the signs of heat exhaustion are becoming vital priorities in protecting older adults.
