Heatwaves increase risks of stroke and circulation issues

Medical experts warn that high summer temperatures and sudden weather changes can increase health risks, specifically regarding stroke and circulation. Neurologist Dr. Mihailo M. Mirković notes that ischemic strokes, caused by blood vessel blockages, are more frequent during hot months due to dehydration, loss of fluids and electrolytes, and heart rhythm disturbances.

While weather changes are not a direct cause of stroke, they act as a factor for sensitive individuals, particularly those with hypertension. Sudden blood pressure spikes can increase the risk of hemorrhagic strokes. Managing chronic conditions like high blood pressure, diabetes, and cholesterol remains the most effective prevention.

Additionally, high temperatures can exacerbate venous circulation issues. Heat causes blood vessels to dilate, making it harder for blood to return from the legs to the heart. This can lead to swelling, fatigue, and a heavy sensation in the limbs, especially in individuals with existing vascular problems or those who remain sedentary for long periods.
