双语健康:多喝水对老人身体好吗

  Is it good for the old man to drink more water

  多喝水对老人身体好吗

  Increasing fluid intake by about a liter per day appears to have no negative effects in healthy older men,Dutch researchers report.

  荷兰的研究人员在一份研究报告中表示,对于那些健康的老年人来说,每天多喝约1升的水,对身体不会产生任何负影响。

  Dr.Mark G.Spigt of Maastricht University and colleagues note in the Journal of the American Geriatric Society that older people are often dehydrated,partly because their sensation of thirst may be blunted.On the other hand,the elderly can easily become overly hydrated,because their kidneys tend to work less efficiently.Retaining excess water can dilute the level of sodium in the body,which can have serious consequences.

  荷兰马斯特里赫特大学的马克·斯皮格特博士和他的同事在《美国老年病学协会杂志》上指出,老年人经常会发生身体脱水的现象,其中部分原因在于他们对于口渴的感觉已变得非常迟饨了。然而,另一方面,由于老年人肾脏的工作效率已经每况愈下,因此,他们也很容易处于体内含水量超标的状态。体内含有的水分过多会导致身体里铀的含量被冲淡,这可能会引发非常严重的后果。

  "We did this analysis,"Spigt told Reuters Health,"because it was unknown whether it could do harm to hydrate elderly people.Despite the lack of evidence on this topic many people assume all kinds of effects;some claim positive effects,others warn against overhydration." 纽约时报中英文网 http://www.qqenglish.com

  斯皮格特博士在接受路透社健康部的采访时说:"我们之所以进行这种分析,是因为目前还不清楚老年人补充摄取水分是否会对身体造成伤害。尽管关于这个问题还缺乏明显的证据,但许多人已经假设出各种可能的影响;有些人说老年人多喝水会对身体产生积极作用,而另一些人则警告说要避免身体含水量超标的现象发生。"

  To investigate the general effects of increased fluid intake,the researchers examined data from a study involving 141 healthy men aged 55 to 75 years.In random order they were either advised to increase their water intake by a liter and a half per day,or were given a spoonful of a placebo syrup per day.

  为了证实补充饮水量会对老年人产生怎样的影响,研究人员对141名年龄在55岁至75岁之间的身体健康的老人进行了一项研究。这些老人被随机分成了两组,其中一组被建议每天比平时多喝1.5升水,而另一组则每天都会喝一匙不含药性的糖浆。<-->纽约时报中英文网 http://www.qqenglish.com<-->

  After 6 months,the men urged to drink more water had managed to boost their daily fluid intake by an average of about a liter per day.There were no significant differences between the two group in blood pressure,sodium level or the filtration rate of the their kidneys.

  6个月之后,那些被鼓励多喝水的老年人已经能够将每天的水分摄入量平均增加1升左右。在对这两组老年人进行了血压、体内铀含量及肾脏过滤速度方面测试之后,发现他们之间并没有明显的差异。

  The researchers thus conclude that the advice to increase fluid intake had no negative effects.

  研究人员因此得出最终结论——建议老年人每天增加水分的摄入量,这不会对他们的身体产生任何负面影响。

  Summing up,Spigt added,"It seems unreasonable to worry about the harmful effects of drinking extra water."However,he warned,"This does not mean that one cannot drink too much.Excessive intakes of water-more than 10 liters-can be harmful."

  作为总结,斯皮格特补充说那些担心多喝水会对身体健康造成不良影响的想法,看上去是毫无道理的。"然而,他也提出了警告这个研究结果并不意味着一个人可以随心所欲、毫无节制地喝水。过量饮水,例如每天喝10多升水,一定会给身体带来害处。"
