It's summer!
夏天来啦！
It's time for Squeaks and I to get out our swimsuits, our cool shades, and head outside for some fun in the sun!
是时候让我和吱吱拿出泳衣，戴上凉爽的墨镜，去外面享受阳光下的乐趣了!
But I need to make some smart choices before we go outside.
但在出门以前，我还要做几件事。
I need to wear sunscreen, because I don't want to end up getting a sunburn!
我要涂防晒霜，因为不想被晒伤！
Squeaks doesn't need to worry about sunburns, since he's a robot.
吱吱不需要担心这个问题，因为他是个机器人。
But we humans can get a sunburn when we stay out in the sun too long and don't protect our skin.
但我们人类要是在太阳底下待太久，又没有做好肌肤防护措施的话，就很可能被晒伤。
Even though the rays of the sun feel nice and warm, and are important for all kinds of life on the Earth, some of the rays from the sun's light can harm our skin.
尽管阳光让人感觉舒适温暖，而且对于地球上的所有生物都至关重要，有些光线会对我们的皮肤造成伤害。
Now, our skin does have something in it that helps to protect it from these harmful rays.
我们的皮肤中，确实有一些东西可以帮助保护它免受这些有害射线的伤害。
But sometimes, like when you're outside all day, that's not enough.
但是在一些情况下，例如你在户外待了一整天，这些保护是不够的。
If too many of these rays reach your skin, your skin can become damaged, or hurt.
如果你的皮肤暴露在了太多有害射线之中，那么它就很可能受损或受伤。
When skin gets damaged, the body does its best to fix it as soon as possible.
肌肤一旦受伤，身体就会拼尽全力修复它。
It sends more blood to the damaged area, which causes the skin there to get pink or red, and feel warm when you touch it.
体内的血液会集中到受伤的区域，这会导致了那部分的皮肤变粉或发红，还会发热。
The damaged area can feel really sore, and some of the skin can also peel off.
受损区域会感到非常疼痛，也有可能出现脱皮的情况。
These are all signs of sunburn.
这些都是晒伤的迹象。
There are lots of things that can affect whether you get a sunburn or not.
影响晒伤的因素有很多。
People with lighter skin sunburn more easily, and spending more time outside can also lead to more of a sunburn.
比如防晒霜擦得不够多，待在户外的时间太长。
But anyone can get a sunburn.
但是所有人都可能晒伤。
Luckily, there are plenty of different things we can do to keep from getting one.
幸运的是，我们有很多的预防措施。
For example, wearing clothes that cover our skin and completely block the sun's light can keep those harmful rays from getting to the skin on our bodies.
比如，穿能遮住皮肤并完全阻挡阳光的衣服可以阻止有害光线伤害肌肤。
And wearing a hat can keep those rays from causing a sunburn on our heads.
戴帽子也能防止头部晒伤。
We can also try to spend less time in the sun when its rays are brightest—that's usually between ten in the morning and four in the afternoon.
我们也可以试着在阳光最明亮的时候少出去晒太阳——通常是早上十点到下午四点之间。
But one of the easiest things we can do is to wear sunscreen.
但涂防晒霜是最简单的。
Sunscreen can be a lotion, a cream, or a spray.
它可以是乳液，面霜或者喷雾。
But no matter what kind of sunscreen you use, it keeps some of the sun's rays from getting to your skin, and can help stop a sunburn.
无论你用的是哪种，它都能阻止太阳光触及皮肤，并能帮助防止晒伤。
Most sunscreens work by either soaking up those harmful rays, kind of like a sponge, or by reflecting them, kind of like a mirror.
大多数防晒霜要么像海绵一样吸收有害射线，要么像镜子一样反射它们。
Most experts say that you should put sunscreen at least ten minutes before you go outside.
大多数科学家们都说至少要在出门十分钟前涂好防晒。
And you should put on lots of it!
一定要涂够量！
It's a good idea to get some help putting on sunscreen, especially in places that are kind of hard to reach, like all over your back.
有时候你还需要寻求一些帮助，特别是在你很难够到的地方，比如你的整个背部。
You might also want to get help putting it on other places — especially places you might not think about, like your ears, the backs of your legs, and the back of your neck!
还有一些你可能根本没想过的地方，例如耳朵，腿背还有脖子后面！
And once you get your sunscreen on, you should make sure you keep it on!
一旦你涂上了防晒，就应该坚持下去！
It's a great idea to take a break every few hours and to put on some more sunscreen, especially if you're running around and getting sweaty, or you're swimming at the pool or the beach.
最好每隔几个小时就休息一下，补涂一些防晒，尤其是在你跑步出汗，或者在泳池或者海滩游泳以后。
So, enjoy your time in sun this summer … but don't forget to wear your sunscreen!
好好享受夏日的阳光吧……但也别忘了要涂防晒！
