冷天长时间泡热水 小心心脏健康

A long soak in the bath during the colder months could hold some unexpected dangers, a Japanese study has found.  
日本一个研究发现，冬天洗澡时长时间浸泡在热水里会引起一些意料不到的危险。

The researchers from Kyoto Prefectural University found that enjoying a hot tub could spell trouble for the heart.
京都府立大学的研究人员发现享受一个热缸浴会引起心脏问题。

They found the rate of cardiac arrests during bathing were ten times higher in winter than in summer.         
他们发现冬天洗澡时心跳停止比夏天的高出10倍。

The team, led by Chika Nishiyama, based their study on data from nearly 11,000 cardiac arrests in the western prefecture of Osaka between 2005 and 2007.  
由Chika Nishiyama带领的研究小组，根据2005年到2007年大阪西部约1.1万人心跳停止进行研究的。

Prior to the cardiac arrest, 22 percent of people had been sleeping, 9 percent had been bathing, 3 percent had been working, and 0.5 percent had been exercising. The rest had been doing "nonspecific" or unknown activities.   
心跳停止之前，有22%的人在睡觉，9%洗澡，3%工作，0.5%锻炼。其余的在做“非特殊的”或未知活动。

When looking at cardiac arrest rates, at the top of the list was 54 arrests per 10 million people per hour of bathing, followed by 10 per 10 million people per hour of exercising.
考虑到心脏骤停率，1千万人中，洗澡时每小时54人心脏骤停，是最高的，接下来是运动时每小时10人心跳停止。

For bathers, the risk was tied to outside temperatures, with more cardiac arrests on colder days.
对于洗澡的人，这些风险是受到温度的影响，寒冷的天气更多人心跳停止。

While it's still unclear how to explain the link, getting into a hot tub on a chilly day causes a rapid blood pressure drop, which stresses the heart.               
尽管如今还不知道如何解释它们之间的联系，但是在寒冷的天气里进入热的浴缸会导致血压快速下降，增加心脏的压力。

'Preventive approaches such as warming a bathroom and hallway or refraining from taking a deep, hot bath could be important for high risk people,' Dr Nishiyama wrote in the journal Resuscitation.
“如给浴室和走廊加温或避免长时间的热水澡这些预防措施对高风险人群非常重要。”Nishiyama在《复活》杂志中写道。

Hot baths are very important in Japan since traditional homes are not well-insulated as in the west and central heating is quite uncommon. Thousands flock to the country's numerous hot springs for recreation.
在日本热水澡是非常重要的，因为传统家庭保温系统没有西方国家好，而且集中采暖也很不普遍。成千上万人聚集到国家许多温泉里娱乐消遣。
