Resting heart rate: how pulse changes can signal hidden health issues

Resting heart rate (RHR) serves as a primary marker for assessing cardiovascular health without specialized equipment. Stable pulse readings typically indicate normal heart function, while persistent deviations from an individual's baseline may signal underlying issues, ranging from micronutrient deficiencies to thyroid dysfunction. What is resting heart rate The pulse represents the rhythmic expansion and contraction of arterial walls caused by the ejection of blood from the heart. This metric is closely linked to general metabolism; for instance, a body temperature increase of 1°C can raise the heart rate by 8–10 beats per minute. To obtain an accurate measurement, physical exertion and stress factors must be excluded. Readings taken immediately upon waking are considered the most informative.
