白富美還是黑皮豬 看你選對遮陽傘了嗎
Umbrellas aren’t just for rainy days. As everyone knows, they’re also great tools for blocking the sun。
除了能擋雨，傘還是遮陽利器。這一點地球人都知道。
But picking the right umbrella is tricky. You have to combine scientific know-how with fashion wisdom to make the right selection。
但是，挑選一把合適的傘實屬不易。需要科學與時尚相結合，才能做出正確的選擇。
To help you outshine others on the streets and effectively protect your skin, here we have some suggestions。
爲了幫助大家在防曬的同時，還能吸引衆人的眼球，以下是我們的一些建議：
1. Understand the UV protection factor
瞭解紫外線防護係數
Just like sunscreens, parasols are categorized with an ultraviolet protection factor (UPF) level indicating their ability to block ultraviolet rays (UV). UV rays are harmful radiation emitted by the sun and pose dangers to our skin ranging from minute tanning to even skin cancer and cataracts. A parasol labeled as UPF 30+ lets in less than one-thirtieth of UV rays. According to national standards, only umbrellas made of materials that have UPF 30+ and restrict the penetration of UV rays at 5 percent or less are qualified products that can be said to block UV rays. For daily use, you can choose parasols that are labeled at least UPF 30+. But if you stay outside for a longer time, settle for UV umbrellas or UV parasols that are labeled UPF 50+ or above, according to , a general information website。
和防曬霜一樣，遮陽傘也有紫外線防護係數(UPF)等級，用於表明阻擋紫外線效果的好壞。紫外線是由太陽散發的有害射線，對於皮膚有一定的危害，可能導致輕微曬傷，甚至導致皮膚癌和白內障。一把有UPF 30+標識的遮陽傘，能穿透它的紫外線不高於三十分之一。根據國家標準，只有UPF 30+和紫外線穿透率不低於5%的材料，才能算得上是防紫外線產品。日常生活中，可以選擇UPF 30+或防曬係數更高的遮陽傘。但是，根據綜合信息網站的建議，如果在戶外停留時間較長，應該選擇防曬係數至少爲UPF 50+的防紫外線傘或遮陽傘。
2. Fabrics matter
面料很重要
You might only consider the pattern of an umbrella to be worth paying attention to, but don’t ignore fabrics! Common umbrella fabrics include satin, polyester, cotton, nylon and other microfiber materials. But studies show that polyester’s ability to block UV rays is better than other materials’. It absorbs and reflects UV rays more effectively。
你可能僅僅考慮了傘的圖案，卻忽略了它的面料。一般傘的面料包括緞子、滌綸、棉布、尼龍以及其他微纖維面料。但是研究表明，滌綸阻擋紫外線的效果比其他面料都要好。滌綸可以更有效地吸收並反射紫外線。
Nowadays, it’s said umbrellas with black coatings inside block the sun better than those with silver coatings. But according to The Mirror, which once did an experiment on umbrellas, their UV-blocking abilities are almost the same. So, don’t throw more money at buying umbrellas with black coatings, as silver is just as good。
目前，有種說法認爲，比起銀色塗料，傘內的黑色塗料可以更好地阻擋太陽光。但是，據英國《鏡報》報道，根據他們做的試驗，這兩種塗料阻擋紫外線的效果幾乎是相同的。所以，不要浪費銀子去買黑色塗料的傘啦，銀色塗料同樣是不錯的。
Also, black fabric is better. The color can absorb the UV rays to the maximum. This year, black umbrellas with colorful patterns inside are particularly popular。
再者，黑色面料好一些。黑色可以最大限度地吸收紫外線。今年，傘內有五顏六色圖案的黑傘特別受歡迎。
3. Consider details
考慮細節
Some girls might prefer to choose light and small collapsible umbrellas that can be put in their handbags. But you should ensure an umbrella has a wide diameter to provide maximum protection and minimum exposure. Umbrellas with arcs between 50 and 60 inches (about 1.3 to 1.5 meters) in diameter aresufficient. To resist the wind, choose sturdy umbrellas. Look at the number of ribs in the umbrella. The more they are in number, the sturdier the umbrella will be。
有些女孩子可能會選擇輕巧的摺疊傘，以便放進包包裏。但應該確保的是，傘可以提供最大的保護直徑，將暴露在陽光下的範圍維持在最低限度。傘弧直徑在50-60英寸(1.3米-1.5米)就足夠了。爲了防風，還應該選擇比較堅固的傘。挑選時你可以看看傘骨的數量，數量越多，傘就越堅固。
4. Myths about multipurpose umbrellas
晴雨兩用傘的“神話”
Many advertisements and commercials claim that their umbrellas can block both UV rays and the rain. But expert analyzes reveal that once a parasol is used to block the rain, its UV coating erodes. Gradually, it will lose its ability to block the dangerous rays, CCTV reported. So, if you want to keep your parasol long-term, prepare another umbrella for rainy days。
很多廣告都宣稱，他們的傘既可以防紫外線，又能擋雨。但根據中央電視臺的報道，有專家分析，一旦遮陽傘在雨天用過，其紫外線塗層就會被侵蝕，會漸漸失去阻擋紫外線的功效。所以，如果想延長遮陽傘使用壽命，下雨天還是準備其他傘吧。
