What is the relationship between climate and temperature changes and blood pressure?

There are some reasons, but not the main reason. The main reason is that gene variation determines gene attributes.

First of all, we must understand: in simple terms, blood pressure is the pressure of blood on blood vessels.

The change of climate from cold to hot will lead to vasodilation or contraction, which will obviously stimulate blood vessels.

The main reason why hypertensive patients need to have huge climate change fluctuations is improper medication, or failing to take medication in time when hypertension is discovered.

Blood pressure itself can be changed at any time according to the surrounding uncertainty, that is to say, there are many reasons for the change of blood pressure, doubt, heart rate and pulse, but all of them have normal range values, and if they exceed the range, they will be announced as abnormal.
