I bet a lot of pizza bagels that you've taken the most widely used psychoactive substance in the world, caffeine.

我敢打賭，你們都吃過最多人使用的精神活性物質：咖啡因。

Wanna guess how many cups I've had today?

Over 90% of adults living in the U.S. use caffeine regularly, consuming around 200 milligrams each day.

美國超過九成的成年人會規律攝取咖啡因，每天大約 200 毫克。

The FDA says it's safe to have up to 400 milligrams a day.

美國食品藥物管理局說，一天攝取 400 毫克以內是安全的。

Caffeine is found in a variety of foods and drinks, and even some medicines.

咖啡因存在於各種食物和飲料中，甚至有些藥物裡也有。

The amount of caffeine in each varies by product.

每種產品的咖啡因含量都不一樣。

For instance, 8 ounces of hot chocolate has about 7 milligrams.

舉例來說，八盎司的熱巧克力大約有七毫克。

While some cough medicines have 25 milligrams.

而有些止咳藥則含有二十五毫克。

For coffee, the range is generally between 10 and 20 milligrams per ounce.

咖啡的話，每盎司的含量通常在十到二十毫克之間。

So a typical 12 ounce cup of coffee could have as much as 247 milligrams of caffeine.

所以一杯標準的十二盎司咖啡，咖啡因含量可能高達兩百四十七毫克。

But there are some products with loads more.

And consuming these could be really dangerous.

Caffeine stimulates the brain, specifically the central nervous system.

咖啡因會刺激大腦，特別是中樞神經系統。

This is the part responsible for receiving, processing and responding to sensory information.

這是負責接收、處理和回應感官資訊的部分。

Caffeine makes you feel more awake and alert.

咖啡因會讓你感覺更醒著、更警覺。

It can also improve your mood, memory and physical endurance.

它也能改善你的情緒、記憶和體能。

Some exploratory research has also found that drinking a modest amount of coffee below the 400 milligram threshold can lower the risk of certain illnesses and medical conditions such as Alzheimer's, Parkinson's disease, cryosis of the liver, kidney stones, certain cancers and stroke.

一些探索性研究也發現，攝取低於 400 毫克閾值的適量咖啡，可以降低罹患某些疾病和醫療狀況的風險，例如阿茲海默症、帕金森氏症、肝硬化、腎結石、某些癌症和中風。

So caffeine clearly has a wide impact on the body, well beyond jump starting your brain.

所以咖啡因對身體的影響顯然很廣泛，遠不止是啟動你的大腦。

It also stimulates the release of the hormones noradrenaline and norepinephrine.

它也會刺激去甲腎上腺素和正腎上腺素這兩種荷爾蒙的釋放。

These cause your heart to beat faster and faster and faster and faster and increase your blood pressure.

這會讓你的心跳越來越快，血壓也會升高。

For your average healthy person, this isn't much of a problem as long as you stay below the recommended amount.

對一般健康的人來說，只要攝取量在建議範圍內，這就不是什麼大問題。

For some, like those with heart related medical conditions, even moderate amounts of caffeine could be dangerous.

對某些人來說，像是患有心臟相關疾病的人，即使是適量的咖啡因也可能很危險。

But consuming high amounts above 400 milligrams can be dangerous for anyone.

但攝取超過 400 毫克的劑量，對任何人來說都可能有害。

When you start consuming too much caffeine, you may get an upset stomach, a headache, or feel nervous or jittery.

當你開始攝取過多咖啡因時，可能會出現胃部不適、頭痛，或是感到緊張或焦躁不安。

But that's nothing compared to an overdose.

但這跟過量攝取相比，根本不算什麼。

An overdose of caffeine can cause rapid or irregular heartbeat and breathing trouble, potentially resulting in death.

咖啡因過量可能導致心跳過快或不規則，以及呼吸困難，甚至可能致命。

This rarely happens from drinking coffee.

這種情況很少會因為喝咖啡而發生。

Most people who overdose on caffeine are using caffeine pills or powders.

大多數咖啡因過量的人，都是使用咖啡因藥丸或粉末。

These products contain much higher levels of caffeine and are referred to as pure or highly concentrated caffeine products.

這些產品含有更高濃度的咖啡因，被稱為純咖啡因或高濃度咖啡因產品。

These high concentrations make the difference between a safe amount and a toxic amount incredibly small.

這些高濃度的產品，讓安全劑量和有毒劑量之間的差異變得非常小。

The FDA warns that safe quantities of these products can be difficult or nearly impossible to measure accurately with common kitchen measuring tools.

美國食品藥物管理局警告，使用常見的廚房量具，很難或幾乎不可能準確測量這些產品的安全份量。

That's because even small amounts of these products contain a lot of caffeine.

這是因為即使是這些產品的少量，也含有大量的咖啡因。

For instance, 1 teaspoon of pure powdered caffeine is equal to about 28 cups of coffee.

舉例來說，一茶匙純咖啡因粉末的咖啡因含量，大約等於 28 杯咖啡。

But the FDA estimates that less than a half a teaspoon, which equals 1200mg, is enough to cause toxic effects like seizures.

但美國食品藥物管理局估計，不到半茶匙的量，也就是 1200 毫克，就足以引起癲癇等毒性反應。

I think I'll just stick with gorging on pizza bagels.

我想我還是專心吃 pizza bagels 好了。

So how many cups of coffee do you drink a day?
