We've all had those days where we curl up in our best blanket and never step outside to greet the sun.

我們都有那些蜷縮在最舒適毯子裡，根本不出門去迎接陽光的日子。

It's fun to have lazy vampire days like this, but what would happen if you never got any sunlight at all?

像這樣度過慵懶的吸血鬼日子很有趣，但如果你從不曬太陽會發生什麼呢？

Well, while it looks like getting sunlight is not absolutely necessary to live, having the sun's rays hug your skin is pretty important to staying healthy.

看起來曬太陽並不是生存的絕對必要條件，但讓陽光的光線覆蓋你的皮膚對於保持健康相當重要。

One of the biggest benefits of getting sunlight is how it helps you get vitamin D.

曬太陽的最大好處之一就是它幫助你獲得維生素 D。

While some other essential vitamins must be obtained through food, vitamin D is able to be synthesized in your skin by a photosynthetic reaction that can be caused by exposure to the sun's radiation.

雖然其他一些必需的維生素必須通過食物獲得，但維生素 D 可以在你的皮膚中透過光合反應合成，這反應是由暴露於陽光輻射引起的。

Vitamin D is essential for supporting your bone integrity and has a protective role against chronic morbidities such as diabetes and cardiovascular diseases.

維生素 D 對支撐骨骼完整性至關重要，並在預防慢性病如糖尿病和心血管疾病方面起保護作用。

Low vitamin D levels have long been linked to poor bone health, and more recent findings seem to correlate inadequate amounts of this precious vitamin to problems ranging from multiple sclerosis to prostate cancer.

維生素 D 濃度低長期以來一直與骨骼健康狀況不佳有關，最近的研究結果似乎將這種珍貴維生素的攝取量不足與從多發性硬化症到前列腺癌等一系列問題聯繫起來。

If you never were exposed to any sunlight, you would almost definitely be lacking in this important nutrient unless you were taking vitamin D supplements.

如果你從不接觸任何陽光，除非你服用維生素 D 保健食品，否則你幾乎肯定會缺乏這種重要的營養素。

It's almost impossible to get the amount of vitamin D you need from food alone, as only a few foods naturally contain it and most of those that do only have it in small amounts.

僅從食物中獲取所需的維生素 D 幾乎是不可能的，因為只有少數食物天然含有它，而且大多數食物中的含量也很少。

Even so, some argue that vitamin D supplementation alone is not as good as vitamin D your body synthesizes in response to sunlight.

儘管如此，一些人認為單獨服用維生素 D 保健食品不如你的身體對陽光反應所合成的維生素 D 效果好。

And when this one guy is exposed to sun, he sparkles apparently, and I still don't know why.

當這個家伙被曝曬太陽時，顯然會閃閃發光，而我仍然不知道為什麼。

Getting sunlight also seems to have other pretty significant benefits.

曬太陽還有其他顯著的好處。

Sunlight and spending time outdoors is thought to help improve your mood.

最近的研究進一步表明，陽光照射到你的皮膚，而不僅僅是眼睛，可以幫助逆轉季節性情感障礙。

Recent research further suggests that light hitting your skin, not just your eyes, can help to reverse seasonal affective disorder.

最近的研究進一步表明，光線照射到你的皮膚，而不僅僅是你的眼睛，可以幫助扭轉季節性情感障礙。

Other studies have found that sunlight alters the levels of nitric oxide in your blood and skin.

其他研究發現陽光會改變血液和皮膚中一氧化氮的水平。

This can lead to lowered blood pressure and a reduced risk of heart disease.

這可以降低血壓並降低心臟病的風險。

Putting this all together makes a pretty significant case for how your life would be far less awesome if you never got any sunlight.

把這一切放在一起，就可以充分證明，如果你沒有陽光，你的生活將會很淒慘。

My animator can make the sun go away anytime you want, so I'm really ha...

我的動畫師可以讓太陽隨時消失，所以我真的很...

Okay... you can bring it back now... please. I don't like the dark.

好吧...你現在可以把它帶回來...拜託。我不喜歡黑暗。

While exposure to the hot ball of glowing gases in the sky definitely has its benefits, too much sun may also be a bad thing.

雖然暴露在天空中熾熱的發光氣體球肯定有其好處，但過多的陽光也可能是一件壞事。

Getting too much sun can cause those pesky sunburns and also suppress your skin's immune system.

接觸過多的陽光會導致討厭的曬傷，也會抑制皮膚的免疫系統。

Sunlight might also be capable of damaging skin cell membranes and put you at a greater risk for certain skin cancers.

陽光也可能損害皮膚細胞膜，使你罹患某些皮膚癌的風險更大。

The Center for Disease Control and Prevention warns that the sun's ultraviolet rays can damage your skin in as little as 15 minutes,

疾病管制與預防中心警告說，太陽的紫外線在短短 15 分鐘內就會損害你的皮膚，

and recommends certain strategies to protect yourself such as hats with brims all the way around and using sunscreen.

並建議採取某些保護自己的策略，例如戴有帽簷的帽子和使用防曬霜。

All in all, it seems like getting sunlight is mostly beneficial to you.

總而言之，曬太陽似乎對你最有好處。

Provided you don't stay out for too long, you should probably avoid a life that avoids the sun.

只要你不在外面待的時間太長，你就應該避免沒有陽光照射的生活。

So are you someone that loves going outside or are you more of a homebody?

那你是喜歡外出的人還是比較宅的人呢？

Let me know in the comments below or tell us what should we talk about next?

請在下面的評論中告訴我，或告訴我們接下來應該討論什麼？

So we've confirmed sunlight is very important, but have you ever wondered what would happen if you never left your bed?

我們已經證實陽光非常重要，但你有沒有想過如果你不離開床會發生什麼？

Check out this episode.
