What are the typical blood pressure norms for a healthy individual?

The typical blood pressure norms for a healthy individual are represented by the reading of 120 over 80 millimeters of mercury (mmHg), often referred to as "120 over 80." This reading is widely recognized as the standard for optimal cardiovascular health. Blood pressure consists of two measurements: the systolic pressure (the pressure in the arteries when the heart beats) and the diastolic pressure (the pressure in the arteries when the heart is at rest between beats).

A reading of 120/80 mmHg indicates that the systolic pressure is 120 and the diastolic pressure is 80, falling within the normal range established by health organizations. This norm is critical as it supports adequate blood circulation while minimizing the risk for cardiovascular diseases, which can arise from consistently high or low blood pressure readings.

In contrast, readings outside this range can indicate potential health risks or conditions that need to be addressed. High readings—such as 150/90—are indicative of hypertension, while lower readings can suggest hypotension or other health concerns. Thus, 120/80 is not just a statistical average; it represents a physiological benchmark for maintaining overall health.
