Lithuania heatwave prompts medical warnings on dehydration and heart risks

Meteorologists forecast temperatures of up to 36 °C across Lithuania. Health experts warn that extreme heat endangers not only people with chronic illnesses but also those who feel healthy but overexert themselves outdoors. Cardiologist Prof. Dr. Vilma Dženkevičiūtė says prolonged heat can cause weakness, headaches, dizziness, fainting, heart‑rate irregularities, and increase the risk of heart attacks or strokes, especially when fluid loss is severe.

Key recommendations include drinking sufficient water—potentially 2–3 L per day during heavy sweating—monitoring electrolyte balance, limiting direct sun exposure to 15–20 minutes at peak hours, wearing light, breathable clothing, and seeking medical help if symptoms appear. People taking blood‑pressure medication should consult doctors, as dehydration can cause dangerous drops or spikes in blood pressure. Electrolyte drinks may help some, but they are not suitable for everyone, particularly individuals with kidney disease or those on potassium‑affecting drugs.
