放心啦，涂防曬霜不會影響維D生成的！

It was previously a common belief that using sunscreen would limit vitamin D production in our bodies.

以前人們普遍認為：使用防曬霜會限制人體產(chǎn)生維生素D。

Three recent studies have debunked this, however, with their results showing that it makes very little difference in most people.

然而最近的三項研究推翻了這一觀點。研究表明涂抹防曬霜對大多數(shù)人來說沒有影響。

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.

我們都需要維生素D，人體內(nèi)的維生素D一部分源于紫外線，這是我們身體對太陽照射做出的反應。我們通過暴露在陽光底下來獲得紫外線輻射，但這同樣可能是有害的，會導致皮膚癌的發(fā)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.

這項研究似乎推翻了一個觀點，即涂抹防曬霜來抵御紫外線會影響人體合成維生素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.

其中一項實驗將三組人送到了Tenerife島，并分別給這三組人不同的防曬方案，這些選擇針對不同水平的UVA和UVB保護。還有一組人被要求待在波蘭，那里的紫外線照射水平要低得多。

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.

研究結果實際上發(fā)現(xiàn)，那些使用SFP15的防曬霜的人群體內(nèi)維生素D含量最高。研究對象的血液在實驗前后都進行了檢測并對比。

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.

該研究的第一作者，倫敦國王學院的Antony Young教授表示，防曬霜可以防止曬傷和皮膚癌，但含有不同成分的防曬霜對維生素D的生成具有未知的影響。實驗是在Tenerife島天氣晴朗的一周內(nèi)完成的，實驗表明防曬霜有利于維生素D的合成，你既可以享受防曬，也可以補充維生素D。
