What is considered normal blood pressure for an adult?

Normal blood pressure for an adult is widely recognized as 120/80 mmHg. This value is considered the standard benchmark in clinical practice and is referred to as optimal blood pressure. The systolic pressure (the first number, 120) represents the pressure in the arteries when the heart beats, while the diastolic pressure (the second number, 80) indicates the pressure in the arteries when the heart is at rest between beats. This range is associated with a lower risk of cardiovascular diseases and is generally maintained by healthy lifestyle choices.

Measurements lower than 120/80 mmHg, such as 110/70 mmHg, may still be normal for many individuals, particularly if they are generally healthy and asymptomatic. However, the optimal benchmark set by health authorities is 120/80 mmHg, making it the most recognized "normal" standard. Blood pressure readings above this target can progressively indicate increased risk for health issues, with 130/90 mmHg and 140/90 mmHg both signifying stages of hypertension. Understanding the significance of these readings is essential for maintaining heart health and preventing complications.
