东芬兰大学和于韦斯屈莱大学的科研人员进行的一项研究表明，经常蒸桑拿可以降低中老年人心血管疾病(CVD)死亡的风险。

The research, which has recently been published in the open access journal BMC Medicine, found that the mortality from CVD among people taking sauna four to seven times a week is 73 percent lower than those using sauna once a week, according to the press release issued by the University of Eastern Finland.
根据东芬兰大学发布的新闻稿，这项最新研究发表在开源期刊《BMC Medicine》上，与每周仅蒸桑拿1次的人相比，每周蒸桑拿4至7次的人因心血管病死亡的风险低73%。

The findings were based on self-reported questionnaire and death cases from cardiovascular causes recorded in documents of death. A total of 1,688 people living in eastern Finland were involved in the research.
该研究结果基于问卷调查以及医院记录的心血管疾病死亡病例，总共涉及1688名生活在芬兰东部的人。

At the beginning of the study, the average age of the participants was 63 years old.

Among them, 51.4 percent were woman and 49.5 percent were man. Data for the study were collected between 1998 and 2015.
其中女性占51.4%，男性占49.5%。研究数据收集于1998年至2015年之间。

The long-term study found the number of cases of CVD mortality decreased as the length of time spent in the sauna per week increased.
这一长期研究发现，心血管疾病死亡率随着每周蒸桑拿时间的增加而降低。

For those who spent over 45 minutes per week in a sauna, the number of cases was 5.1 per 1,000 person years, while the number was 9.6 for those who spent less than 15 minutes in the sauna per week.
对于每周蒸桑拿超过45分钟的人来说，死亡率为千分之5.1，而每周蒸桑拿不足15分钟的人，死亡率为千分之9.6。
