Blood pressure is considered one of the indicators that help doctors assess the health status of the body. More specifically, the health and functioning of the cardiovascular system. Besides healthy people with normal blood pressure, there are also people with low or high blood pressure. So what is the normal blood pressure index in humans?

1. Overview of blood pressure

blood pressure is created by the force of blood circulation in the blood vessels. Blood pressure can change over time and in different situations. Normal and stable blood pressure is the blood pressure index of healthy people who do not have cardiovascular diseases.

What is the normal blood pressure of a healthy person?

1.1. What is blood pressure?

Before learning about normal blood pressure readings, we need to understand what blood pressure is. Blood pressure is the pressure that acts on the blood vessel walls to create a driving force to push blood from the heart to other locations in the body to nourish the cells, thereby maintaining and developing life. Under the contraction of the heart and the resistance of the arterial wall, blood pressure is created.

When the heart is working, the blood pressure index for each beat will be measured from systole to diastole.

1.2. Systolic blood pressure

Systolic blood pressure is the blood pressure index measured when the heart is in a state of contraction. At this time, the pressure of the blood affecting the blood vessel walls is at its highest level, also known as maximum blood pressure. When measuring blood pressure, the systolic blood pressure index will be displayed above and higher than the index below.

Blood pressure is created by the contraction of the heart and the resistance of the blood vessel walls.

1.3. Diastolic blood pressure

Diastolic blood pressure is the blood pressure index measured when the heart is in a relaxed state and is lower than the minimum blood pressure. Diastolic blood pressure will have a lower index level than systolic blood pressure and will be shown below when measuring blood pressure.

2. Normal blood pressure index of adults

For healthy people, blood pressure is always kept at a stable level. Therefore, through measuring blood pressure, people can determine whether their health status as well as the condition of the cardiovascular system is good or not. Normal blood pressure is determined when the systolic blood pressure index does not exceed 130mmHg and the diastolic blood pressure index does not exceed 85mmHg.

Factors affecting diastolic blood pressure lower than 80 mmHg. Specifically, when the measured blood pressure index is less than 120/80 mmHg, it means that your body is reaching the most optimal blood pressure level.

However, if your blood pressure is above or below the normal blood pressure index, the chances of you having high blood pressure or low blood pressure are extremely high. Whether it is high or low blood pressure, it will cause dangerous complications for your body such as: myocardial infarction, stroke, kidney failure, etc.

Therefore, you need to regularly check and measure your blood pressure to be able to identify and detect the disease as early as possible. This will help you have the “golden” time for treatment and quickly recover your health.

The blood pressure index of adults is below 120/80 mmHg

3. Factors affecting blood pressure index

Blood pressure changes with age. The further away from the aorta, the lower the blood pressure. Blood pressure reaches its lowest level in the venous system. Blood pressure index will change depending on a number of factors such as:

• When we exercise vigorously or after exercise, the heart beats faster, causing blood pressure index to increase. In some cases, it can cause high blood pressure. On the contrary, when the heart beats slower, the heart muscle force is lighter, blood pressure can decrease.
• As people age, blood vessel walls lose elasticity or the lumen narrows, creating resistance in the blood vessels, which is also a factor that changes blood pressure index.
• When the body is injured, losing a lot of blood also causes blood pressure to decrease.
• Eating too salty foods for a long time increases blood volume. This is also the cause of high blood pressure.
• Unstable psychological conditions such as anxiety and strong agitation are also factors that can cause blood pressure to change.

Under the influence of cardiovascular diseases also causes blood pressure to change.

4. Methods to keep blood pressure normal and stable

Keeping your blood pressure at a normal level or slightly below normal is essential. Because they are the decisive factors in maintaining good health as well as helping you limit complications of high or low blood pressure. Some methods to keep blood pressure at an optimal level that you should pay attention to are:

4.1. Implement a scientific diet

The diet has a significant impact on the stability of blood pressure. A scientific, reasonable diet will help your body maintain a suitable weight, avoiding diseases such as obesity. You should not eat foods with high salt content. Replace greasy foods with foods high in fiber such as green vegetables and fruits. Minimize carbonated and alcoholic beverages such as beer, wine, and soft drinks.

Eat lots of fruit and supplement with adequate nutrients to help maintain normal, stable blood pressure.

4.2. Regular exercise

In addition to a scientific diet, creating a healthy lifestyle is also extremely necessary to keep blood pressure normal. You should exercise regularly, limit staying up late, and smoking. Applying these things will not only help you have a healthy body but also keep your spirit comfortable, happy and optimistic. These are the necessary factors to keep blood pressure at the best level.

4.3. Regular health check-ups

A regular health check-up every 6 months is something you should do. Regular check-ups not only help you detect diseases that your body may encounter early, but also help you prevent them. Regular blood pressure measurement helps you detect early abnormal changes such as low or high blood pressure. From there, you can get timely and effective treatment methods.
