Abstract
The use of a recently developed noninvasive automated blood-pressure device has revealed a striking relationship between human communication and elevations in blood pressure in both normotensive and hypertensive individuals. Individuals with higher resting baseline pressures tended to show greater increases during talking than did those with lower pressures. In some hypertensive individuals increases blood pressure greater than 25-40% occurred within 30 sec after the initiation of human speech. Links between difficulties surrounding human communication and elevations in blood pressure are discussed.
