Did you know?

Average normal blood pressure differs based on sex and changes according to your age!

An average person’s blood pressure tends to remain constant throughout the day. But there are minor fluctuations in the blood pressure readings, for example when you are relaxed your blood pressure decreases. And when you are stressed your blood pressure increases.

Persistently high or chronically low blood pressure is associated with health risks, which is why it is important to monitor your blood pressure.

In this article, we will look at the different average blood pressure chart readings you should have according to your age, health risks associated with “abnormal” blood pressure, and what you can do to monitor your blood pressure.

What Do The BP Numbers Mean?

The blood pressure readings comprise of two numbers the systolic blood pressure and diastolic blood pressure. 

The first number, the systolic pressure measures the highest blood pressure in your heart when your heart beats or contracts. The second number in the reading, the diastolic blood pressure refers to the lowest blood pressure in your heart in between the heart beats or when it dilates or expands.

So now whenever you look at the reading of blood pressure that states 120/80 mm Hg you will know which one is the systolic reading and which one is diastolic.

The abbreviation mm Hg is the standard unit of measure for Blood pressure which stands for “millimeters of mercury.”
