以前人们普遍认为:使用防晒霜会限制人体产生维生素D。
Three recent studies have debunked this, however, with their results showing that it makes very little difference in most people.
然而最近的三项研究推翻了这一观点。研究表明涂抹防晒霜对大多数人来说没有影响。
We all need vitamin D, which the body creates as a response to ultraviolet radiation. We get this radiation through exposure to the sun, but it can also be harmful and cause skin cancer.
我们都需要维生素D,人体内的维生素D一部分源于紫外线,这是我们身体对太阳照射做出的反应。我们通过暴露在阳光底下来获得紫外线辐射,但这同样可能是有害的,会导致皮肤癌的发生。
So, this is great news, as the studies seem to have debunked the idea that wearing sunscreen to protect against UV rays doesn’t impact vitamin D synthesis.
这项研究似乎推翻了一个观点,即涂抹防晒霜来抵御紫外线会影响人体合成维生素D。
One of the studies sent three groups to Tenerife, and gave each of them different sunscreen options that had differing levels of UVA and UVB protection. Another group were asked to stay where they lived in Poland, where UV levels are much lower.
其中一项实验将三组人送到了Tenerife岛,并分别给这三组人不同的防晒方案,这些选择针对不同水平的UVA和UVB保护。还有一组人被要求待在波兰,那里的紫外线照射水平要低得多。
The study actually found that those who’d used SPF15 with broad spectrum protection had the highest levels of vitamin D. Subjects’ blood was tested before, during, and after the holidays.
研究结果实际上发现,那些使用SFP15的防晒霜的人群体内维生素D含量最高。研究对象的血液在实验前后都进行了检测并对比。
Lead author of the study Professor Antony Young, of King’s College London, said of: ‘Sunscreens can prevent sunburn and skin cancer, but there has been a lot of uncertainty about the effects of sunscreens on Vitamin D. Our study, during a week of perfect weather in Tenerife, showed that sunscreens, even when used optimally to prevent sunburn, allowed excellent vitamin D synthesis’.Further studies showing similar results are due to be published by the BMJ, with findings meaning you can enjoy the sun – protected – and still get your vitamin D fix.
该研究的第一作者,伦敦国王学院的Antony Young教授表示,防晒霜可以防止晒伤和皮肤癌,但含有不同成分的防晒霜对维生素D的生成具有未知的影响。实验是在Tenerife岛天气晴朗的一周内完成的,实验表明防晒霜有利于维生素D的合成,你既可以享受防晒,也可以补充维生素D。
