正确使用空调对身体有好处

2011-03-18 17:27

  北京的夏天正在向酷热的顶峰冲击。为了抵抗炎热,无论商场、办公场所还是家里,空调成为主角。而随着空调的普及,长时间呆在空调房中所带来的不适和疾病也越来越普及,空调病成为现代都市人一年一度的季节性疾病。

  所谓“空调病”其实是一种长时间呆在空调环境下,因空气不流通、环境得不到改善而引起的一系列病症,表现为头晕、发热、盗汗、身子发虚、记忆力减退以及皮肤发紧发干、易过敏、皮肤变差等症状。

  一般来说,引起空调病的原因主要有两个,一是室内的密封环境和空调本身的内部环境容易滋生各种细菌、霉菌;据统计,在开着空调五六个小时的密封的室内,氧气下降13.2%,大肠杆菌升高1.2%,红霉色菌升高1.11%,白喉菌升高0.5%,其他对呼吸道有害的细菌也有不同程度的增加,细菌的增加会让人更加容易染上疾病;另一个原因是夏季空调室内的温度大大低于外面的温度,长时间呆在空调环境里,会使得人体表面的毛孔收缩,不能正常排汗,一旦遭遇到周围的环境温度发生突然的变化,就会引起内分泌的紊乱。

  医生表示,“如果不注意,无论身体素质如何,有空调的地方就有染上空调病的可能!”,因此,在夏季预防“空调病”和预防中暑同样重要。

  Less use of air conditioners would be better for us all

  A strict no-air-conditioning ban was enforced for 87,000 Taiwanese students taking the college entrance examinations this month despite temperatures in many areas reaching 34 to 36 degrees Celsius.

  Although this long-term practice is being promoted as a pragmatic means to ensure fairness, since air conditioning is not available at all exam locations, rather than for environmental reasons, it nevertheless offers a good opportunity for the country to reconsider its addiction to air conditioning.

  If students can manage without A/C in the heat of examinations, could not the rest of the population go cold turkey once in a while?  If not 'Off,' then 'Down,' since air conditioners consume energy and contribute to climate change in proportion to each degree they are set below ambient temperature.【外语*教育网编辑整理 www.for68.com

  Vehicle A/C systems can be a cause of sinusitis in some people, while poorly maintained air conditioning may lead to the proliferation of micro-organisms such as Legionella pneumophila, the cause of Legionnaires' disease.

  The problem with new high-tech machines is that they present a sizable contribution to man-made climate change. Cooling agents such as CFCs and their modern replacements are greenhouse gases with far more global-warming potential than carbon dioxide should they leak into the atmosphere.

  It is everyone's responsibility to minimize his or her own contribution to the problem.
