Factors that affect vital signs -ANSWER_ The human body is influenced by both emotional and physical factors. Prior to a dental appointment, for example, the patient may have had a hot or a cold beverage, either of which would alter the oral temperature. Or, a patient may be fearful of an upcoming injection; thus, his or her blood pressure and respiration may be higher than at a previous reading. When an increase in metabolism occurs (such as during strenuous exercise), vital sign measurements also typically increase.
