时差N小时 为什么生病的时候容易脱水?(下)

Two key ingredients of metabolic¹ reactions are water and oxygen.

新陈代谢作用的两大关键因素是水和氧。

Increased metabolism² uses more water and also makes you breathe faster, to supply the extra oxygen.

新陈代谢加快会消耗更多的水分，也会导致呼吸加快以补充足够的氧气。

And guess what? As you breathe faster, you breathe out more moisture, along with more carbon dioxide.

你猜接下来怎么样？呼吸加快的同时也将呼出更多的水分和二氧化碳。

Even if you don’t have symptoms that cause obvious water loss–like a runny nose, sweating, vomiting³ or diarrhea–a cold or flu can dehydrate⁴ you in hidden ways.

即便没有出现能引起水分流失如流鼻涕、出汗、呕吐和腹泻等明显症状，感冒或流感也能通过隐蔽的方式引发脱水。

Just a slight rise in body temperature requires more water for metabolic reactions and breathing.

哪怕体温升高一点，都需要更多的水分来维持加快的新陈代谢作用和呼吸。

On top of all that, when you’re sick you just might not feel like eating or drinking as much as usual.

最重要的是，当你生病时，饮食方面可能不比平常。

That’s why Mom keeps reminding you to drink your fluids!

这也是妈妈一直提醒你喝水的原因！
