Sensory neurons and the sympathetic nervous system in relation to increased skin temperature of free upper limb with application of hot compresses to the back

我们对健康成年女性的背部进行了10分钟的热敷，之后我们测量了皮肤温度和皮肤血流量。热敷的应用导致背部、背部周围和手部的皮肤温度升高，以及指尖的皮肤血流量增加。即使在热敷30分钟后，手部皮肤温度也增加了约1°C，并且受试者能够感受到手部的温暖。此外，在大鼠身上证实了从星状神经节向掌垫投射的神经元。我们的研究结果表明，对背部进行热敷不仅可以温暖他们的背部，还可以温暖他们的手。

We applied hot compresses to the backs of healthy adult women’s for 10 min, after which we measured both skin temperature and skin blood flow. The application of hot compresses resulted in increased skin temperature on the back, around the back, and on the hands, as well as increased skin blood flow in the fingertips. Skin temperature on the hands increased by approximately 1°C, even at 30 min after application of hot compresses, and subjects were able to feel the warmth in their hands. In addition, neurons projecting from the stellate ganglia to the palmar pad were confirmed in rats. Our results suggest that application of a hot compress to the back, warms not only their back, but also their hands.
