What is the normal diastolic blood pressure for adults?

The normal diastolic blood pressure for adults typically ranges between 60 mmHg and 80 mmHg. A diastolic reading of 79 mmHg or under is considered within the normal range, indicating that the heart is resting between beats and that the blood pressure is not elevated at that phase of the cardiac cycle. Maintaining blood pressure within this range is important for overall cardiovascular health, as elevated diastolic pressures can increase the risk of heart disease and other complications.

Choosing 79 mmHg or under aligns with established guidelines for healthy blood pressure, thereby confirming it as the correct answer. Understanding normal blood pressure ranges helps healthcare providers assess a patient's cardiovascular health and determine if any intervention is necessary.
