The relationship of local skin temperature and the onset of sweating to the local cutaneous blood flow was studied in the forearm and calf. The purpose of the investigation was to appraise the possible relation of sweat gland activity to the cutaneous vasodilatation which has been attributed to bradykinin or to intracranial temperatures. The onset of sweating was not marked by any apparently related increases in the rate of cutaneous blood flow. On the contrary, the onset of sweating was followed often by a stabilization or even a decrease in the level of cutaneous blood flow. The relations of the latter to the local skin temperature were complex, particularly in the forearm. There appeared to be additional unidentified influences, possibly vasomotor, operating on the skin vessels during transitional phases in the relation of skin temperature to blood flow.

C3h Mice

C3H mice were bred at 30°C and 22°C. At 28 days of age the lengths of the sacral and caudal vertebrae were measured from radiographs and related to the local skin temperature. Growth of the sacral and proximal caudal vertebrae was slightly retarded in the hot environment, but the distal caudal vertebrae showed increased growth which could be quantitatively related to an increase in skin temperature. This suggests that in hot climates the increased growth of peripheral organs of some mammals is due to local increases in tissue temperature.

Skin Temperatures

In order to determine the effect of application pressure on the accuracy of skin temperature measurements for area contact sensors, low values of pressure (2-20 mm Hg) were applied to the mid-thigh and to the lateral aspect of the trochanter of human subjects using a thin, circular disk with a thermistor mounted in the base. From measurements of the local skin temperatures, it was determined that a pressure of 2 mm Hg is adequate to measure the skin temperature accurately. Applying larger pressure results in higher local skin temperatures with the thighs showing larger temperature increases than the trochanters. The results of a finite difference analysis indicate that the increases in skin temperature at higher pressures can be accounted for by the physical phenomena associated with the penetration of the sensor into the tissue. After the release of pressure, the local skin temperature immediately decreased for all subjects indicating little or no reactive hyperemia was occurring. A method of compensating for the changes in local skin temperature which are due to whole body transient thermal effects was also developed. Use of this method allows the effects of the local pressure application to be separated from the transient environmental effects.

A compact 4-W gas-stream heater for use with ventilated sweating capsules is described. The heating element is constructed from two modified 75-omega power resistors connected in parallel and contained in the capsule gas inlet tube. Heater power is controlled with integrated circuits which compare the output of a thermocouple, measuring either capsule skin or air temperature, with a predetermined target temperature. The unit responds fairly slowly to sudden large changes in target temperature, but once a steady state is achieved, maintains target temperature levels despite changes in evaporative heat loss. The device is well suited for studies in which local skin temperature or capsule air temperature must be elevated and clamped while the effects of other local stimuli or central thermoregulatory activity are studied, and in studies where the skin temperature effect on transepidermal water loss must be controlled.

1. The effects of locally induced alterations in skin temperature on the postural changes in skin blood flow of the foot were assessed in 38 healthy subjects in a constant-temperature environment (22 ± 0.5°C, mean ± sd). 2. Moderate local cooling and warming of the foot (26–36°C) was induced by blowing cold or hot air. Higher ranges of temperature (38–44°C) were achieved by a thermostatically controlled disc heater. 3. Skin blood flow was measured before and during each change in local skin temperature using a laser Doppler flowmeter with the foot maintained at heart level, and placed passively 50 cm below the heart. Blood flow was measured in two skin areas: (i) the dorsum of the foot, where arteriovenous anastomoses are absent, and (ii) the pulp of the big toe, where these anastomoses are relatively numerous. 4. It was found that within the physiological temperature range of 26–36°C the normal postural fall in foot skin blood flow was preserved, whereas it was markedly attenuated or totally abolished at higher temperatures (38–44°C). The pattern of response was quite similar in areas having or lacking arteriovenous anastomoses. 5. It is suggested that the failure of postural vasoconstriction observed at the higher skin temperatures might contribute to some of the problems of cardiovascular adaptations seen in a hot environment.
