那么怎樣的空(kong)(kong)(kong)(kong)氣(qi)(qi)才(cai)是健康(kang)的?根據(ju)世界(jie)衛生組(zu)織(zhi)規定,負氧(yang)離子濃度(du)(du)在(zai)1000個/cm3以(yi)上可滿足健康(kang)基本(ben)需(xu)要(yao),若低于1000/cm3個以(yi)下則可視為空(kong)(kong)(kong)(kong)氣(qi)(qi)被污染,濃度(du)(du)在(zai)1000~1500個/cm3的空(kong)(kong)(kong)(kong)氣(qi)(qi)被視為清新的空(kong)(kong)(kong)(kong)氣(qi)(qi),濃度(du)(du)高(gao)于1500個/cm3的空(kong)(kong)(kong)(kong)氣(qi)(qi)才(cai)能被稱為是健康(kang)空(kong)(kong)(kong)(kong)氣(qi)(qi)。也就是說富含高(gao)濃度(du)(du)負氧(yang)離子的空(kong)(kong)(kong)(kong)氣(qi)(qi),才(cai)是健康(kang)的空(kong)(kong)(kong)(kong)氣(qi)(qi)。
以國際著名的廣西巴(ba)馬長壽村為(wei)例,研(yan)究表(biao)明(ming),巴(ba)馬長壽老人比較多(duo)的原因(yin),與(yu)當地空氣負離(li)子含量很高有關(guan)。
巴(ba)馬(ma)(ma)(ma)當(dang)地(di)的(de)空(kong)(kong)(kong)氣負(fu)離子大多(duo)是由(you)針(zhen)葉植(zhi)物(wu)的(de)葉子在光電效應下,發(fa)生(sheng)(sheng)尖端(duan)放(fang)電而產生(sheng)(sheng)。針(zhen)葉植(zhi)物(wu)的(de)葉子作為(wei)空(kong)(kong)(kong)氣負(fu)離子的(de)發(fa)生(sheng)(sheng)尖端(duan),源源不斷向外釋放(fang)空(kong)(kong)(kong)氣負(fu)離子,而空(kong)(kong)(kong)氣負(fu)離子的(de)壽(shou)命很(hen)短,只有(you)1~2分鐘(zhong)(環境(jing)惡劣(lie)的(de)地(di)方只有(you)幾秒鐘(zhong)),無法由(you)風力來輸(shu)送(song)。由(you)此(ci)說來,當(dang)地(di)的(de)人想要(yao)長壽(shou)的(de)話,難(nan)道(dao)都需(xu)要(yao)靠近植(zhi)物(wu)1~2米(mi)來主動呼(hu)吸空(kong)(kong)(kong)氣負(fu)離子嗎?當(dang)然不是,廣西巴(ba)馬(ma)(ma)(ma)的(de)空(kong)(kong)(kong)氣負(fu)離子活性非常高,能夠快速的(de)擴散出去,在巴(ba)馬(ma)(ma)(ma)上空(kong)(kong)(kong)形成了一(yi)個龐(pang)大的(de)空(kong)(kong)(kong)氣負(fu)離子浴環境(jing),造就(jiu)了當(dang)地(di)居民的(de)長壽(shou)。
由此可(ke)以證明,只有(you)活性(xing)高(gao)、遷移距離遠(yuan)的(de)負(fu)離子,也就是生(sheng)態負(fu)氧離子,才能發揮其良好的(de)生(sheng)物活性(xing),穿透人(ren)體(ti)血腦屏障,發揮療效(xiao)。
