Sweating and vasodilatation in the cutaneous circulation were investigated during passive body heating in eight borderline hypertensive subjects and in eight normotensive controls, matched for age, sex and body mass. Blood flow through the finger and forearm was examined in relation to changes in oral temperature; blood pressure, heart rate and sweating in the forehead and forearm were also measured. Systolic blood pressure decreased in borderline hypertensive subjects during the early stages of heating and then returned to baseline, but increased in normotensives. Increases in skin blood flow and decreases in cutaneous vascular resistance were similar in both groups. Thus, cutaneous vasodilatation during moderate body heating did not differ between normotensive subjects and subjects with mildly elevated blood pressure. These findings do not rule out attenuation of cutaneous vasodilatation in mildly hypertensive subjects during more intense heating.
在八名临界高血压受试者和八名年龄、性别及体重相匹配的正常血压对照者被动身体受热期间，对皮肤循环中的出汗和血管舒张情况进行了研究。检测了手指和前臂的血流与口腔温度变化的关系；还测量了血压、心率以及前额和前臂的出汗情况。在受热早期，临界高血压受试者的收缩压下降，随后恢复至基线水平，但正常血压者的收缩压升高。两组的皮肤血流增加和皮肤血管阻力降低情况相似。因此，在适度身体受热期间，正常血压受试者与血压轻度升高的受试者之间的皮肤血管舒张并无差异。这些发现并未排除在更强烈受热期间轻度高血压受试者的皮肤血管舒张减弱的情况。
