Normal Blood Pressure

Blood pressure refers to the exerted force by circulating blood on the walls of one’s blood vessels. Blood pressure is generally referring to arterial pressure, meaning, the pressure in one’s larger arteries (the blood vessels which take blood away from one’s heart). Abnormal blood pressure can lead to many unwanted occurrences, this article explains how you can monitor and control your own blood pressure.

What Is Normal Blood Pressure Reading?

The blood pressure considered normal is defined as 120/80, although the actual number varies depending on age and gender, and the exact “normal” level has changed over the course of many years.

Which Number Is More Important, Top or Bottom?

Generally speaking, the top number is more important because a high systolic reading is often associated with an increased risk of developing cardiovascular disease for those over the age of 50. Most people will experience a rise in systolic pressure as they grow older due to cumulative stiffness of larger arteries, increased occasions of vascular and cardiac disease, as well as prolonged accumulation of plaque.

What Is the Normal Blood Pressure Reading According to My Age?

Research has clearly shown a correlation between age and rising blood pressure. This rise is thought to occur to accommodate the need for increased amounts of oxygen and nutrients. For many decades, the assumption that one’s systolic pressure can be calculated by adding one’s age to 100 for men and subtracting 10 for women. For example, a man aged 45 would likely have a systolic blood pressure of 145.

See the table below featuring the average normal blood pressure for different ages.

What Is Considered a High Blood Pressure?
