23/06/2026Thousands of people across Ireland are being urged to take extra care as temperatures are set to soar above 30 degrees during an expected heatwave in the hottest spell of the year so far. Health experts have issued a warning to anyone taking medication for high blood pressure, heart conditions, or circulation problems, saying the coming heatwave could increase the risk of dehydration, dizziness, and other potentially serious complications. The alert comes after Met Éireann issued a nationwide Status Yellow high-temperature warning, with forecasters predicting sweltering conditions and uncomfortable nights over the coming days.

Experts are warning that soaring temperatures can place additional strain on the body, especially for those already living with cardiovascular conditions. When the weather gets hotter, your heart has to work harder to keep your body cool, and for people with high blood pressure or existing heart problems, that can increase the risk of complications.

Those taking blood pressure medication are also encouraged to monitor their symptoms and blood pressure more regularly during the warm spell. Warning signs that require urgent medical attention include confusion, severe fatigue, rapid heartbeat, nausea, excessive sweating, and swelling in the arms or legs. Experts have also warned that people with angina and heart failure may be more vulnerable during periods ofextreme heat.

Meanwhile, those with heart failure are being advised to speak to their GP if they are struggling with symptoms or have concerns about managing medication during the heatwave. Health officials are also reminding the public to watch for signs of heat-related illness. Symptoms of heat exhaustion can include headaches, dizziness, excessive thirst, nausea, muscle cramps, heavy sweating, and a temperature above 38 degrees.
