北京人缺氧!军事医学科学院专家近日的研究成果显示:90%的北京人或多或少地缺氧,环境污浊,生活节奏加快,脑力、体力消耗增加,都使无处不在的氧气,成为愈来愈珍贵的稀缺资源。氧气是维系生命的重要物质、空气中含有20．1%(一般为20．95%——编者)的氧气,成人每天大约需500升氧,如果空气中缺乏氧气或者人体耗氧量增加,就会出现一系列缺氧症状,如头晕、耳鸣,严重时可危及生命。
Beijing people hypoxia! Military Academy of Medical Sciences experts recent research results show that: 90% of Beijing people more or less hypoxia, environmental pollution, accelerated pace of life, increased mental, physical exertion, make the ubiquitous oxygen, a Increasingly rare and scarce resources. Oxygen is an important substance that sustains life. The air contains 20.1% (usually 20.95% - editor’s) of oxygen. Adults need about 500 liters of oxygen per day. If the air lacks oxygen or the body’s oxygen consumption increases, There will be a series of symptoms of hypoxia, such as dizziness, tinnitus, serious life-threatening.
