Skin temperature during sunbathing—relevance for skin cancer
Photochemical & Photobiological Sciences, 2014It has been found that exposure to heat and infrared radiation (IR) can be carcinogenic, and that a combination of ultraviolet radiation (UVR) and IR possibly amplifies carcinogenesis. To investigate how the skin temperature is affected by sunbathing, we measured the skin temperature on 20 healthy volunteers over 6 days' sun holiday in Egypt ...

Freezing temperature of finger skin
Journal of Applied Physiology, 1976In 45 subjects, 154 frostnips of the finger were induced by cooling in air at -15 degrees C with various wind speeds. The mean supercooled skin temperature at which frostnip appeared was -9.4 degrees C. The mean skin temperature rise due to heat of fusion at ice crystallization was 5.3 degrees C.The skin temperature rose to what was termed the ...

Tactile discrimination and skin temperature
Journal of Applied Physiology, 1960Ten subjects immersed an index finger in water at 0.75°C for 40 minutes. Two-edge threshold discrimination was tested during cooling of the finger and subsequent spontaneous rewarming due to cold vasodilatation. There was a marked deterioration of tactile discrimination at finger skin temperatures below about 8°C, although the curve showing the mean ...

Skin temperature and phototest evaluation
Photodermatology, Photoimmunology & Photomedicine, 1996The degree of erythema following UV irradiation is known to depend upon skin temperature at the time of UV exposure. We investigated whether changes in skin temperature at the time of erythema assessment influenced the level of erythema. Twenty‐two healthy people (mean age 26 years) were irradiated with solar simulated radiation on previously UV un ...

Skin Temperature Biofeedback and Migraine
Headache: The Journal of Head and Face Pain, 1978SYNOPSIS Skin temperature biofeedback was used in treating two groups of patients with migraine. The experimental group received true auditory feedback controlled by increases in skin temperature of their fingers, while the control group received a similar “positive” signal independent of skin temperature changes and controlled by the

Measurement of facial skin temperature
Journal of Dentistry, 1990It is essential to know the pattern of facial skin temperatures in normal subjects to be able to objectively assess differences in cases of nerve injury. Thirty healthy adults were selected at random to investigate the pattern of facial temperature using liquid crystal thermography and an electronic thermocouple system.

Digital Skin Temperature and Biofeedback
Perceptual and Motor Skills, 1994The present study simultaneously compared the skin temperature of the index and the little fingers during hand warming using biofeedback. There was a 5-min. baseline recording followed by a 10-min. session during which subjects attempted to increase skin temperature using the index finger with biofeedback in the form of lights and sound.

Skin temperature response to cryotherapy
Archives of Physical Medicine and Rehabilitation, 2002To compare the localized skin-cooling effects of 2 cryotherapy modalities and to review the clinical relevance of the results.Randomized controlled trial with repeated measures.Laboratory experiment.Convenience sample of 20 volunteers (13 women, 7 men), ages 21.3 to 44 years (mean, 31.3 +/- 6.8 y).A flexible frozen gel pack, a 454 g packet of frozen ...

Low Skin Temperatures Produced by New Skin Refrigerants
The Journal of Dermatologic Surgery and Oncology, 1985Abstract. Temperatures produced by Cryosthesia – 30°C, Cryosthesia – 60°C, and Frigiderm were measured in mini pigs. Cryosthesia – 60°C and Cryosthesia – 30°C were both found to rapidly lower skin temperatures to levels that have been shown to cause cell injury, necrosis, and loss of melanocytes.

Temperature Discrimination in the Skin
Nature, 1964THERMORECEPTORS reported in the skin of the cat, rat and dog1–3 had properties similar to the thermoreceptors found in the tongue4. The afferent fibres, however, had low conduction velocities characteristic of non-myelinated axons. The receptors fell into two categories: those excited by a rise and those excited by a fall in cutaneous temperature ...
