Rising Temperatures Prompt Global Health Warnings

Health experts across several countries warn that the recent surge in high temperatures raises the risk of heat‑related illnesses such as heat‑stroke, severe dehydration, brain haemorrhage and heart attacks. Vulnerable groups—including the elderly, people with hypertension, diabetes or cardiovascular disease, and children whose thermoregulation is less developed—are especially at risk. Authorities advise drinking at least 2–2.5 L of water daily, avoiding outdoor activity between 10:00 a.m. and 4:00 p.m., wearing light, breathable clothing and hats, staying in shade, using cool showers and ventilating indoor spaces. For children, parents should watch for sudden fever, weakness, headache, skin flushing, reduced urine output and altered consciousness; immediate cooling, fluid intake and medical attention are recommended. The US American Heart Association emphasizes that heat forces the heart to work harder, increasing the chance of arrhythmia or cardiac events. In addition, misuse of air‑conditioning can spread Legionella bacteria and trigger respiratory illnesses, prompting advice on regular filter cleaning and avoiding direct cold drafts. Following these preventive steps can reduce the health burden of the heat wave.
