Why is blood pressure higher in winter? I see

It's cold, and many people may have the impression that oral antihypertensive drugs are good in summer, but they can't control their blood pressure in winter. Why is blood pressure higher in winter than before?

First, blood vessels contract when they are cold.

The temperature will drop significantly in winter, and blood vessels will contract when it is cold. Vascular contraction will increase the resistance of blood circulation. When the peripheral vascular resistance increases, the patient's blood pressure will also increase.

Second, the capacity increases in winter.

On the one hand, vasoconstriction increases peripheral resistance, on the other hand, vasoconstriction reduces sweating in cold weather, while slow blood flow in winter reduces renal perfusion and urination. Sweating less and urinating less will increase blood volume and blood pressure.

Third, due to the reduction of exercise.

When the temperature is cold in winter, our desire for activities decreases and outdoor activities decrease. The consequences of reduced exercise are increased obesity and increased blood pressure.

Four, caused by winter tonic

Everyone knows that it needs to be made up in winter. With the improvement of living standards, the realization of supplements has greatly increased, and supplements have also brought obesity and increased capacity load. These will also raise blood pressure.
