Summary
Skin thermal diffusivity, crucial for laser therapy, was studied alongside melanin and erythema. No significant correlation was found, suggesting other factors influence skin
Area of Science:
- Dermatology
- Biophysics
- Thermal Science
Background:
- Skin thermal diffusivity is vital for applications like laser therapy and cryogenic cooling.
- Understanding skin's thermal properties is essential for cosmetic and clinical dermatology.
- Previous research indicates a role for physiological parameters in skin thermal behavior.
Purpose of the Study:
- To investigate the correlation between skin thermal diffusivity and melanin content.
- To examine the relationship between skin thermal diffusivity and erythema levels.
- To assess the influence of these parameters on skin's thermal properties in 102 participants.
Main Methods:
- Utilized an in-house device employing transient temperature measurement to determine skin thermal diffusivity.
- Assessed melanin content and erythema using a colorimeter across various body locations.
- Performed statistical analysis to identify correlations between thermal diffusivity, melanin, and erythema.
Main Results:
- Measured skin thermal diffusivity values align with existing literature.
- No statistically significant correlation was identified between skin thermal diffusivity and melanin content.
- No statistically significant correlation was identified between skin thermal diffusivity and erythema.
Conclusions:
- Melanin content and erythema do not appear to be primary determinants of skin thermal diffusivity.
- Factors such as skin hydration and epidermis thickness may exert a more significant influence.
- Findings offer insights into skin's complex thermal regulation for dermatological applications.

01:25Body Temperature
949
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

01:14Temperature Measurement Sites
1.7K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

01:43Thermosensation
30.4K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

01:20Mechanisms of Heat Transfer II
3.2K
In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

01:14Changes in Skin Color: Clinical Perspectives
2.0K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
