Abstract

ABSTRACT The Global Solar Ultraviolet (UV) Index provides limited information on health effects due to over-exposure. This study investigated the change in skin physiology in response to solar UV irradiation and the protective efficacy of a sunscreen. Fourteen female participants were divided into two groups, sunscreen users and non-users, and for 8 weeks they received solar irradiation and were monitored for change in the erythema-index (E-index), melanin-index, skin capillary blood flow, skin moisture, transepidermal water loss (TEWL), and skin temperature. The E-index and TEWL responded proportionally to solar radiation and could serve as indices of acute health effects from UV exposure. In the sun-radiated area, the E-index and TEWL measured on the forearm of the non-users were 111.3% and 138.4% of the levels determined for the users, respectively. Although thermal sensation and thermo-physiology were correlated, physiological monitoring was preferred over thermal sensation survey in evaluating the impact of solar UV irradiation.

太阳紫外线照射对皮肤的急性影响和防晒霜的使用效果

全球太阳紫外线(UV)指数提供了有限的关于过度暴露对健康影响的信息。本研究探讨了太阳紫外线照射下皮肤生理机能的变化和防晒霜的保护功效。14名女性参与者被分为使用防晒霜和不使用防晒霜两组，她们接受8周的太阳照射，并监测红斑指数(E-index)、黑色素指数、皮肤毛细血管血流、皮肤水分、经皮失水(TEWL)和皮肤温度的变化。e -指数和TEWL与太阳辐射成正比，可作为紫外线照射对急性健康影响的指标。在阳光照射区域，非使用者前臂的e指数和TEWL分别为使用者的111.3%和138.4%。虽然热感觉与热生理相关，但在评价太阳紫外线照射的影响时，生理监测优于热感觉调查。

期刊介绍： Environmental Pollutants & Bioavailability is a peer-reviewed open access forum for insights on the chemical aspects of pollutants in the environment and biota, and their impacts on the uptake of the substances by living organisms. Topics include the occurrence, distribution, transport, transformation, transfer, fate, and effects of environmental pollutants, as well as their impact on living organisms. Substances of interests include heavy metals, persistent organic pollutants, and emerging contaminants, such as engineered nanomaterials, as well as pharmaceuticals and personal-care products as pollutants.
