生氣時做劇烈運動會增加心臟病發風險

Exercise has always been seen as a major mood booster and stress reliever: It boosts endorphins and can help distract you from whatever's on your mind, which is why it feels good to walk it off when you're frustrated.

人們一直以來都認爲，運動是幫助放鬆心情、緩解壓力的主要途徑：它可以刺激提高內啡肽，並且能幫助你暫時忽略腦袋裏所想的東西，這也是爲什麼當你感到傷心難過的時候，散步能讓人好受很多。

But new research published in the Heart Association journal Circulation suggests that while hitting the gym super hard when you're pissed might do wonders for your mental health, it could do more physical harm than good.

但一項發表在《心臟協會雜誌》的最新研究表明，當你感到憤怒時，去健身房過度地運動可能會對你的精神健康產生意想不到的後果，對自己的身體健康反而是弊大於利。

When researchers polled 12,461 heart attack patients, they found that roughly one in seven people had been angry or upset, or reported physical exertion in the hour leading up to the event.

研究人員對12461名心臟病患者進行了調查，他們發現大約1/7的患者在心臟病發作的前一小時內都呈現憤怒或者傷心難過的狀態，或者是進行過強體力活動。

But people were three times more likely to have heart attacks after they'd been feeling mad and participated in some sort of strenuous activity during that same 60-minute window.

而在同樣的60分鐘時間段內，一直處於生氣狀態並且進行劇烈運動的人心臟病發作的機率比平時要大3倍。

While the study only associates angry exercise to heart attack risk without proving cause and effect, the connection makes perfect sense.

儘管這項研究沒有說明原因和影響，只是將憤怒鍛鍊與心臟病發作的風險聯繫起來，但這其中的關聯是完全有道理的。

Both physical activity and intense emotion can raise your blood pressure and heart rate, putting greater demands on the circulatory system.

身體活動和強烈的情緒波動都能引起血壓升高，心率加快，這對身體循環系統有極大的需求。

If your arteries are already littered with plaque, the combination of exercise and emotion could easily lead you to develop a blood clot that ends up triggering a heart attack, the leading cause of death in the U.S.

如果發現你的動脈血管表面已經出現了斑塊，帶情緒的運動就會輕易導致血栓，最終引發心臟病。在美國，心臟病發作是導致死亡的首要原因。
