Hypertension is also a genetic disease.
Not smoking or drinking is not the root of the problem.
The root of the problem is not exercise.
My hereditary disease is hypertension, and my grandfather and father are both hypertensive.
My father discovered it after he was 50, but I still have no symptoms of hypertension. There is a simple reason. My father was an athlete when he was young, and now he often exercises (note: I am under 30, smoking and not drinking, but playing basketball and running in the morning).
However, since your boyfriend's blood pressure is not very high now, if you maintain it, follow your friend's method on the third floor. If your blood pressure rises, you should advise him to take some "Golden Nine".
My father has used 1 for many years, and the effect is good. The high pressure has dropped from 170 in the initial inspection to 135 now, which is very stable.
