减少紫外线辐射 (UV) 的暴露对于预防紫外线引起的皮肤和眼睛疾病至关重要。阴影可以提供显着的紫外线防护。需要更多的实证研究来量化建筑遮阳所提供的紫外线防护，以指导疾病预防实践和对遮阳投资的信心。这项研究量化了夏季两个城市公园内建筑遮阳下相对于无遮阳被动休闲区 (PRA) 的紫外线水平。在一项随机对照试验中，在 144 个公园的 PRA 中心和外围进行了 n = 1144 次紫外线测量，作为 2010 年至 2014 年每个城市三轮招募中公园游客使用 PRA 的前测试和后测试措施的一部分。预测试后，36 个 PRA 接受了内置遮阳，108 个没有。对 PRA 处 UV（每 30 分钟标准红斑剂量 (SED)）的前后变化进行回归分析；和环境预测因子。内置遮阳 PRA 中心的平均 UV 从测试前到测试后有所下降 ( = 3.39, = 0.93 SED)，相对于对照 PRA (p < 0.001)，调整环境 SED、（余弦）太阳高度和云量的协变量后，变化 = −3.47 SED。云层减少，太阳高度增加，阴影下的紫外线水平增加。不同颜色设计的紫外线没有发生显着差异。使用带有遮阳布设计的内置遮阳帘可以显着减少紫外线照射，为遮阳帘使用者提供相当大的保护。在晴朗的日子里，如果长时间处于阴凉处，建议补充防晒措施。
Reducing exposure to ultraviolet radiation (UV) is crucial for preventing UV-induced diseases of the skin and eyes. Shade may offer significant protection from UV. More empirical research to quantify the UV protection offered from built shade is needed to guide disease prevention practices and confidence in investment in shade. This study quantified UV levels under built-shade relative to unshaded passive recreation areas (PRAs) over summer months in parks in two cities. In a randomized controlled trial, n = 1144 UV measurements were conducted at the center and periphery of PRAs in a total sample of 144 public parks as part of pretest and posttest measures of use of the PRAs by park visitors for three recruitment waves per city during 2010 to 2014. Following pretest, 36 PRAs received built-shade and 108 did not. Regression analyses modelled pre-post change in UV (Standard Erythemal Dose (SED) per 30 min) at PRAs; and environmental predictors. Mean UV at the center of built-shade PRAs decreased from pretest to posttest ( = 3.39, = 0.93 SED), a change of = −3.47 SED relative to control PRAs (p < 0.001) adjusting for the covariates of ambient SED, (cosine) solar elevation and cloud cover. Clouds decreased and solar elevation increased UV levels under shade. No significant differences in UV by shade design occurred. A substantial reduction in exposure to UV can be achieved using built-shade with shade cloth designs, offering considerable protection for shade users. Supplementary sun protection is recommended for extended periods of shade use during clear sky days.
