High blood pressure, why cold hands and feet?

Cold hands and feet when blood pressure is high may be related to factors such as cold environment, hypertension and atherosclerosis.

1. A

cold environment can stimulate the sympathetic nervous system, causing vasoconstriction, causing blood pressure to rise, and after vasoconstriction, it can also reduce the amount of blood flowing to the hands and feet, resulting in cold hands and feet.

2. Hypertension and

hypertension can lead to increased blood pressure in patients, and can also cause harder blood vessel walls and enhanced vasoconstriction. After vasoconstriction, it can also cause blood flow to slow down., poor blood flow, cold hands and cold feet.

2. Atherosclerosis

Atherosclerosis can cause stenosis of the lumen, leading to increased blood pressure, and can also cause stenosis and insufficient blood supply to the blood supplying arteries of the limbs. Insufficient blood supply will affect the energy supply and oxygen supply to the limbs, resulting in reduced heat production in limbs and cold hands and feet.
