早晨的一杯咖啡會(huì)讓你心情愉悅嗎

Preparing coffee and drinking a cup in the morning can be an excellent way to start the day. Something is soothing about the routine, and it feels great when the caffeine helps wake you up and lift you out of your sleepy fog. Do you ever feel like coffee just puts you in a better mood?

早上準(zhǔn)備咖啡和喝杯咖啡是開始一天的絕佳方式。當(dāng)咖啡因幫助你清醒過來，把你從困倦的迷霧中解脫出來時(shí)，你會(huì)感覺很棒。你有沒有覺得咖啡能讓你心情好一點(diǎn)?

According to WebMD, people in the United States drink more than 600 million cups of coffee every day. There are many health benefits from coffee, including reducing your risk of cancer, stroke, Parkinson's, dementia, and Alzheimer's. Typically, four cups of coffee can be safe, but more than that can have adverse effects, from increased anxiety to insomnia. On the other hand, you can have too much of a good thing.

據(jù)WebMD統(tǒng)計(jì)，美國(guó)人每天喝6億多杯咖啡。咖啡對(duì)健康有很多好處，包括降低患癌癥、中風(fēng)、帕金森病、癡呆癥和老年癡呆癥的風(fēng)險(xiǎn)。一般來說，四杯咖啡是安全的，但超過四杯咖啡可能會(huì)產(chǎn)生從增加焦慮到失眠的一系列負(fù)面影響。另一方面，你可以擁有太多的好東西。

A typical cup of coffee contains 80 to 100 milligrams of caffeine, and don't forget decaf also contains a bit of caffeine — about two to 15 milligrams per cup. While 400 milligrams of caffeine — or four cups of coffee — is the maximum you should have a day, that can vary per person. Some people are more sensitive to caffeine and should have less. Finding how much coffee you should have in a day can be a trial and error process. If you experience symptoms of overuse of caffeine, like the jitters, cut down on the coffee (via the FDA).

一杯典型的咖啡含有80到100毫克的咖啡因，別忘了無咖啡因咖啡也含有一點(diǎn)咖啡因——大約每杯2到15毫克。雖然400毫克咖啡因——或者四杯咖啡——是你一天最多應(yīng)該攝入的量，但每個(gè)人的攝入量可能會(huì)有所不同。有些人對(duì)咖啡因更敏感，應(yīng)該少喝。找出你一天應(yīng)該喝多少咖啡可能是一個(gè)反復(fù)試驗(yàn)的過程。如果你有過度使用咖啡因的癥狀，比如神經(jīng)過敏，那么就少喝咖啡。

Does your morning cup of coffee put a smile on your face? You're not the only one, and there's science behind it.

早晨的一杯咖啡會(huì)讓你的臉上綻放笑容嗎?你不是唯一一個(gè)，這背后有科學(xué)依據(jù)。

A September 2015 review of seven studies with over 330,000 participants found that drinking coffee can significantly reduce the risk of depression. They found the best dose of caffeine between 68 and 509 milligrams a day — about one to five cups of coffee.

2015年9月，一項(xiàng)對(duì)超過33萬參與者的七項(xiàng)研究的回顧發(fā)現(xiàn)，喝咖啡可以顯著降低患抑郁癥的風(fēng)險(xiǎn)。他們發(fā)現(xiàn)咖啡因的最佳劑量為每天68到509毫克，大約一到五杯咖啡。

Coffee can significantly improve your mood, according to an October 2018 study in Nutrients. Those who drank regular coffee had an improved mood compared to those who drank a cup of decaf or a placebo.

根據(jù)2018年10月《營(yíng)養(yǎng)》雜志的一項(xiàng)研究，咖啡可以顯著改善你的情緒。與喝一杯無咖啡因咖啡或安慰劑的人相比，喝普通咖啡的人的情緒有所改善。

Adenosine is a naturally occurring chemical found in all of your cells, and it makes you feel sleepy. Coffee blocks adenosine, so you feel more alert and ready to concur the day (via StatPearls).

腺苷是一種存在于所有細(xì)胞中的自然化學(xué)物質(zhì)，它會(huì)讓你感到困倦。咖啡會(huì)阻斷腺苷，所以你會(huì)更清醒，準(zhǔn)備好迎接新的一天。

Science confirms coffee is happiness in a mug. So enjoy your morning cup of coffee for these positive benefits.

科學(xué)證實(shí)咖啡是杯中的幸福，所以享受你的早晨咖啡吧。
