最新研究發現 睡眠不足會對心臟有所影響

In a new study, researchers find that sleep deprivation can cause noticeable changes in the heart.
在一項新的研究中，研究人員發現，睡眠不足可導致心臟發生明顯的變化。

In the new study, presented at the annual meeting of the Radiological Society of North America (RSNA), researchers from the University of Bonn in Germany looked at professionals in emergency medical care, who often work erratic hours and late-night shifts while enduring significant stress.
在北美放射學會年會上提出的這項新研究中，來自德國波恩大學的研究人員對從事緊急醫療護理的專業人員進行了研究，他們經常沒有穩定的工作時間且需要值夜班，同時承受着巨大的壓力。

About twenty healthy radiologists had their hearts imaged before and after a 24-hour shift where they got an average of three hours of sleep.
研究對大約二十位健康的放射科醫生在24小時輪班前後進行心臟成像，他們平均睡眠是時間爲三小時。

The study also had their blood pressure and heart rate measured, and they provided blood samples.
研究還測量了他們的血壓和心率，並且讓他們提供血液樣品。

Comparing the two images showed increases in heart strain, which can be a precursor for heart problems.
比較前後兩個圖像，可以看出心臟壓力的增加，這可能是心臟問題的前兆。

The doctors also showed increases in blood pressure, heart rate and thyroid hormones, which are released in response to stress.
這些醫生還出現血壓升高、心率加快和甲狀腺激素增加的情況，這些是由於壓力而表現出來的。

The study size was very small, and more research is needed to fully understand the relationship between sleep and heart health.
該研究的規模非常小，需要更多的研究來充分了解睡眠和心臟健康之間的關係。

But the researchers point out that their study is one of the first to look at the real effects of sleep deprivation on the heart, and since there are many people who do regular shift-work, continued research could provide meaningful insight into the health effects of working on little sleep.
但是研究人員指出，他們的研究是最先觀察睡眠不足對心臟的真實影響的研究之一，而且由於有很多人經常倒班工作，持續的研究可以對睡眠不足時進行工作的健康影響提供有意義的見解。
