What is normal blood pressure for everyone?
In attempts to define answers for "What is normal blood pressure?" scientists have conducted a great number of studies in populations across the world. What they found was that the results vary significantly from one country to another and from one region to another within a country. There is a fairly wide normal blood pressure range that came up. So they concluded that normal blood pressure is something that can be arrived at only through constant testing and observation. Currently, normal blood pressure is thought of as that level which tends to produce the longest life expectancy. At this level, the body's systems including the heart and circulatory system work at an optimum level, without excessive strain. This is the level at which the risk of heart diseases and other illnesses is at a minimum. Many factors can influence your blood pressure. Let's assume you are a healthy, normal person. If you are excited, your systolic blood pressure can rise by as much as 50%. Vigorous exercise can produce the same effect -- spiking blood pressure. The blood flow increases as a response to your physical / emotional condition. However, your pressure doesn't stay up at that level. As soon as your level of excitement goes down, or you cease the vigorous exercise, the systolic pressure starts to come down and reaches normal levels. Diastolic pressure is the key to figuring out whether it is a normal reaction or a permanent rise in pressure. If the diastolic pressure stays constant, it can be assumed that the rise in systolic is purely temporary and that your blood pressure is in the normal range. The diastolic pressure depends on the state of your arterioles. If the diastolic is high, it means the arterioles are constricted and blood can't flow as freely as it should. That's why the diastolic pressure reading is more important than the systolic. The former can indicate whether a high reading in the latter is a false positive. That said, if your reading is say, 170/110 or higher, you may end up with fatigue, headaches, dizziness, etc. If the reading goes above 230/130, the risk of heart attacks and strokes goes up very significantly. That is the reason why hypertension is an important indicator of a person's health. And it is important to control it and bring it within limits. The above is a rather lengthy reply to the question "What is normal blood pressure", but it is necessary given that no simple answer exists.
