Many people consider a blood pressure of 120/80 to be normal. However, a person's blood pressure usually goes up and down within a certain range every day, so it's best to use more than one blood pressure reading to determine your average blood pressure. In fact, normal blood pressure can actually fall anywhere in a range from 90/60 to 120/80. Several things (such as lifestyle and family history) can affect a person's normal blood pressure range. High and low blood pressure can cause health problems, so keeping your blood pressure at a proper level is essential to good long-term health.
