"If you didn't have allergies as a kid,

"如果你小時候沒有過敏。

you won't get them as an adult."

你作為一個成年人不會得到它們。"

So, that's a myth.

You can actually develop allergies

at any point in your life.

在你生命中的任何時刻。

Especially now, with people moving to different locations.

特別是現在，隨著人們搬到不同的地方。

The change in climate, location,

get super intense and super severe,

變得超級激烈和超級嚴重。

then it'll be that much harder

那就更難了

to get those symptoms under control.

以使這些症狀得到控制。

So it's a good idea to start early.

Like, if you have pollen allergy in the spring,

比如，如果你在春天有花粉過敏症。

I usually say have the patient start premedicating

我通常會說讓病人開始預服藥物

with antihistamine, nasal spray, or eyedrops

使用抗組胺劑、鼻腔噴霧劑或眼藥水

before the season starts.

在賽季開始前。

I usually recommend as soon as they start seeing

Especially severe seasonal-allergy sufferers,

特別是嚴重的季節性過敏症患者。

we have them take them even two weeks in advance,

Gupta: Tree allergies are mostly a springtime allergen,

古普塔：樹木過敏大多是春季的過敏源。

grass allergies are for summer,

草過敏是夏天的事。

and weed allergies are in the fall.

和雜草過敏是在秋天。

So for people who have tree, grass, and weed,

所以對於有樹、有草、有雜草的人。

normally it would've been maybe from, like,

通常情況下，它可能已經從，如。

April until September that they might have had symptoms.

4月至9月，他們可能出現了症狀。

But now we're seeing even as early as February, actually.

That's actually not true.

Pollens from flowering plants

In order for pollen to cause allergic symptoms,

為了讓花粉引起過敏症狀。

they need to meet three criteria.

They need to be small,

他們需要的是小的。

they need to be light,

他們需要的是光。

and they need to be dry to be carried by wind.

而且它們需要乾燥才能被風帶走。

Gupta: So the pollen in flowers is actually large,

古普塔：所以花中的花粉實際上是很大的。

and it's distributed by insects.

而它是由昆蟲分佈的。

And so that pollen is not in the air,

這樣，花粉就不會在空氣中出現。

which means that it doesn't get into our eyes and nose.

這意味著它不會進入我們的眼睛和鼻子。

However, for tree pollen, weed pollen, and grass pollen,

然而，對於樹木花粉、雜草花粉和草花粉。

because it's light

and because it travels in the air more easily,

then it can get into our eyes

然後它可以進入我們的眼睛

and nose and airways more easily.

That is a myth because local honey

contains pollen collected by bees.

含有蜜蜂採集的花粉。

So those come from flowering plants.

是以，這些來自開花植物。

We mentioned before, pollen from flowering plants

我們之前提到，開花植物的花粉

are not major contributor to seasonal allergies.

不是導致季節性過敏的主要因素。

And also we don't have a lot of studies done

So we cannot know for sure how effective they are

in treating or helping to cure

your seasonal-allergy symptoms.

So I have no problem recommending using honey

所以我沒有問題，建議使用蜂蜜

as a way to soothe your throat, your symptoms.

作為舒緩你的喉嚨、你的症狀的一種方式。

But I would not say it can cure seasonal allergies.

So, that's a myth.

the microscopic flecks of skin that the pet shed.

So the same protein can be also found in their saliva.

是以，在他們的唾液中也可以發現相同的蛋白質。

So it's not the fur,

but rather the shedding of the skin, with their saliva.

而是用它們的唾液脫落皮膚。

It's important to know that even hairless dog can shed,

And so there might be certain breeds

and that's all person-dependent.

So, for example, I have a cat allergy,

是以，舉例來說，我對貓過敏。

but there's certain cats that I do totally fine around,

但有一些貓，我在它們身邊完全沒有問題。

and then there's other cats that

然後還有其他的貓咪

as soon as I walk into someone's home

一走進別人的家門

and they have that cat, I'll start reacting.

而他們有那隻貓，我就會開始有反應。

And so it is not just by touching

是以，它不僅僅是通過觸摸

or rubbing your face against the cat.

或用你的臉蹭貓。

The dander is airborne,

皮屑是通過空氣傳播的。

so that can get into your eyes and nose

這樣就可以進入你的眼睛和鼻子

and into your airways

並進入你的呼吸道

and start causing that IgE antibody to react

並開始引起IgE抗體的反應

and produce that histamine, which causes the symptoms.

Frequent vacuuming is super important.

頻繁的吸塵是超級重要的。

Also air purifiers.

還有空氣淨化器。

And so for somebody that really wants a pet,

For those patients, then we usually do attempt

對於這些病人，那麼我們通常會嘗試

So, allergy shots are immunotherapy,
