Cardiologist Dr. Anastasia Buskakalova stated that blood becomes more viscous in hot weather, which increases the burden on the heart and blood vessels.
The doctor explained that summer itself does not cause increased blood viscosity, but that reduced fluid intake and excessive sweating lead to a decrease in blood plasma volume, which in turn increases the concentration of red blood cells, white blood cells, and platelets. This can increase the risk of blood clots, which may cause serious complications, including stroke.
The doctor advised the elderly, patients with coronary artery disease, high blood pressure, and diabetes to pay special attention to their health during hot weather.
She said: "To prevent dehydration, it is essential to maintain fluid balance in the body, focusing on drinking clean water, and not drinking less than 1.5 liters per day during hot periods."
She added that feeling thirsty, dry mouth, infrequent urination, dark urine, weakness, dizziness, and muscle cramps are among the most prominent early signs of dehydration.
To prevent dehydration, it recommended keeping the body hydrated, eating plenty of water-rich fruits and vegetables, avoiding direct exposure to sunlight, and refraining from strenuous physical activities during peak heat hours as much as possible.
