What is considered a normal/optimal blood pressure reading?

A blood pressure reading of 120/80 mm/Hg is categorized as normal and optimal according to guidelines provided by organizations such as the American Heart Association. This reading indicates that the systolic pressure (the pressure in the arteries when the heart beats) is at a healthy level, and the diastolic pressure (the pressure in the arteries when the heart is resting between beats) is also within an ideal range. A reading of 120/80 mm/Hg maintains a good balance between the two pressures, minimizing the risk of cardiovascular diseases and complications related to high blood pressure.

In contrast, readings above this level, such as 130/90 mm/Hg or 140/100 mm/Hg, may indicate elevated blood pressure, and readings at or over 140/90 mm/Hg can be classified as hypertension, which poses certain health risks. Lower readings such as 110/70 mm/Hg may be within the acceptable range too, but they do not represent the typical benchmark for what is widely regarded as optimal blood pressure for most adults.
