The normal blood pressure reading for an adult is typically considered to be:

A normal blood pressure reading for an adult is generally accepted to be around 120/80 mm Hg. This reading is considered optimal as it reflects a balance between maintaining adequate blood flow throughout the body while minimizing the risk of heart disease and stroke.

The first number, the systolic pressure (120 mm Hg), indicates the pressure in the arteries when the heart beats, while the second number, the diastolic pressure (80 mm Hg), represents the pressure in the arteries when the heart rests between beats.

Blood pressure readings can vary based on various factors, including age, health conditions, and lifestyle, but 120/80 mm Hg is widely recognized as the benchmark for what constitutes a healthy blood pressure for adults. Readings consistently above this range may indicate elevated blood pressure, which can lead to medical concerns if not managed properly.
