How does better diet and exercise lower blood pressure?

Question

I'm looking for the physiological effects on the body

Answer 1

Hi! ok here's how it works.

eating less fat reduces the risk of developing artheriosclerosis, or hardening of the vessels, the smaller your blood vessels are the more forcefully your blood rushes through them, cuasing your BP to raise. decreasing your sodium intake will lower blood pressure. Water in your body naturally follows sodium. and the more volume of fluid in your body the higher your blood pressure is.

Exercise allows the heart to contract more forcefully and more effectively, its called Starling's Law. it decreases your HR and BP, becuase it is more effective. exercise is also a good way decrease the fatty deposits in your vessels, making the diameter of vessel wider. Also when you exercise you are sweating and your body in response to that vasodialates (or widens the veins) the wider the veins the lower your blood pressure is going to be.

think of it like a hose, the smaller the tubing the more pressure the water is coming out. the wider the tubing the slower and less forceful it will come out. exercining opens the veins and allows blood to flow less forcefully. loweing BP

hope this helps!

Answer 2

Jens and Jennifer have good answers for exercise and cholesterol / fats in the diet, but a key dietary factor is SALT. Many people have high blood pressure problems related excessive amount of salt in the diet.

Answer 3

To put it in the simplest terms, it accustoms the heart to work less to get the blood to every part of the body. This is why runners often have a pulse rate of 60 or even lower while those who are dangerously inactive have a pulse rate of over 100.

Answer 4

if your doctor hasn't actully commented on it, your blood pressure isnt that high.. i think your nurse probably just means that its on the high end of the low scale. but a bit of exercise never did anyone harm and it is ment to help lower blood pressure, just don't over do it

Answer 5

all the blood cells lower pressure

Answer 6

it forces out the gunk in the vessels and veins when working out, the constant constriction of these while working out cleanses all the bad junk in the blood allowing slower and less forceful flow of blood to the heart.
