Is blood pressure related to temperature?

Blood pressure has something to do with the weather. Weather changes will lead to the instability of blood vessels, especially the contraction or relaxation of capillaries, which will lead to the increase of blood pressure when blood vessels contract, so blood pressure is directly related to weather and temperature. For example, if the patient is in a cold area for a long time, the patient will have excessive contraction of capillaries, and at this time, the patient will have different degrees of hypertension. In addition, if the patient is in a high temperature area or a hot area for a long time, it will also lead to vasodilation and blood pressure reduction. Therefore, the level of blood pressure is related to weather and temperature, but it is not a direct factor leading to the increase or decrease of blood pressure.
