冷天長時間泡熱水 小心心臟健康
A long soak in the bath during the colder months could hold some unexpected dangers, a Japanese study has found.
日本一個研究發現，冬天洗澡時長時間浸泡在熱水裏會引起一些意料不到的危險。
The researchers from Kyoto Prefectural University found that enjoying a hot tub could spell trouble for the heart.
京都府立大學的研究人員發現享受一個熱缸浴會引起心臟問題。
They found the rate of cardiac arrests during bathing were ten times higher in winter than in summer.
他們發現冬天洗澡時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帶領的研究小組，根據2005年到2007年大阪西部約1.1萬人心跳停止進行研究的。
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%的人在睡覺，9%洗澡，3%工作，0.5%鍛鍊。其餘的在做“非特殊的”或未知活動。
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.
考慮到心臟驟停率，1千萬人中，洗澡時每小時54人心臟驟停，是最高的，接下來是運動時每小時10人心跳停止。
For bathers, the risk was tied to outside temperatures, with more cardiac arrests on colder days.
對於洗澡的人，這些風險是受到溫度的影響，寒冷的天氣更多人心跳停止。
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.
儘管如今還不知道如何解釋它們之間的聯繫，但是在寒冷的天氣裏進入熱的浴缸會導致血壓快速下降，增加心臟的壓力。
'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.
“如給浴室和走廊加溫或避免長時間的熱水澡這些預防措施對高風險人羣非常重要。”Nishiyama在《復活》雜誌中寫道。
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.
在日本熱水澡是非常重要的，因爲傳統家庭保溫系統沒有西方國家好，而且集中採暖也很不普遍。成千上萬人聚集到國家許多溫泉裏娛樂消遣。
