What is the normal range of blood pressure and heart rate

During routine physical examinations, everyone pays close attention to their blood pressure and heart rate values. High or low blood pressure indicates that there is a problem with your blood pressure. It is best to get checked, identify the cause, and treat it symptomatically. Whether the heart rate is normal is also what everyone is most concerned about. A fast heart rate is not good, as it may indicate heart disease. Therefore, it is important for us to understand the normal range of blood pressure and heart rate. Next, I will introduce to you the normal range of blood pressure and heart rate.

1. Normal range of blood pressure

The flow of blood in the body depends on the heart and blood pressure. Blood pressure fluctuates with emotions, environment, diet, etc., so regulation is necessary. When you are nervous or exercising, your blood pressure should be raised to facilitate fighting or escape. The normal blood pressure range for most people is: systolic pressure 140--90mmHg, diastolic pressure 90--60mmHg.

To understand the factors that affect blood pressure, let us make an analogy. The heart and arteries are like a faucet and a hose. When the faucet is turned down, the water pressure will decrease and water will only drip out of the hose. When the faucet is turned up, the water pressure will increase and the water will shoot farther. If the opening of the hose is pressed down to reduce its diameter, the water column will shoot farther.

Basically, what we can see is that when the hose is twisted wider and the diameter of the hose is reduced, blood pressure will rise, and these are the two major factors that affect blood pressure. The heart can provide energy and push blood to various organs, so blood pressure is necessary to maintain life activities. The factors affecting blood pressure are mainly the heart's output and the resistance of peripheral blood vessels.

2. Normal range of heart rate

There are significant individual differences in the heart rate of normal adults at rest, with an average of around 75 beats/minute (between 60 and 100 beats/minute). Heart rate can vary depending on age, gender, and other physiological conditions. The heart rate of a newborn is very high, reaching over 130 beats per minute. Among adults, women generally have a slightly faster heart rate than men. For the same person, the heart rate slows down when quiet or sleeping, and speeds up when exercising or emotionally excited. Under the influence of certain drugs or neurohumoral factors, the heart rate can speed up or slow down. People who regularly engage in physical labor and exercise usually have a slower heart rate. In recent years, a large-sample survey of healthy people in China found that the normal range of resting heart rate for Chinese men is 50-95 beats/minute, and for women it is 55-95 beats/minute. So, heart rate varies with age, gender, and health status.

The above is an introduction to the normal range of blood pressure and heart rate. I believe that after understanding the relevant knowledge about the normal range of blood pressure and heart rate, everyone will be able to have a correct understanding of them. In this way, we can understand whether our physical condition is good, and thus realize the importance of avoiding bad living habits in daily life.
