What is the normal systolic blood pressure for an adult?

The normal systolic blood pressure for an adult is generally considered to be less than 120 mmHg. A reading of 119 mmHg or under falls within the normal range and indicates healthy blood pressure levels, which are crucial for overall cardiovascular health.

In assessing blood pressure, the systolic number is the first reading and represents the pressure in the arteries when the heart beats. Maintaining a systolic blood pressure under 120 mmHg is associated with a lower risk of heart disease and stroke. Readings above this threshold may indicate a gradual increase in blood pressure which can lead to hypertension. Therefore, the choice indicating 119 mmHg or under is particularly significant, highlighting the importance of monitoring and maintaining healthy blood pressure levels in adults.
