万华岩空气负离子

12420

一个令人心驰神往的数字

根据央视13台《新闻直播间》的报道，国家卫健委公布了2020年我国人均预期寿命达到了77岁，从建国初期的35岁提高了43岁。这与我国经济的发展持续向好、医疗技术的不断提高、人们生活条件改善及生态环境的改善有着直接而重要的作用。这其中又以生态环境因素表现得特别突出，比如许多经济条件优越的人跑到秦岭、泰山、巴马、洱海等地建别墅，虽有些因属违建被拆除，但从另一个侧面反映出人们对良好生态环境的追求。还有许多人一年中总会想方设法挤出时间去一些知名生态山庄、或普通农庄、或租一家农房长住或小住一段时间，远离城市的繁杂与喧嚣，释放工作带来的压力，尽情欣赏大自然的青山绿水，呼吸野外清新洁净的空气，以达到康养的目的。

要达到康养目的，空气是一个十分重要的因素，而空气负离子的多少又极大地影响空气的质量，成为衡量空气质量的一个重要指标。万华岩景区就具备这样一个具备优良空气的环境，而且尤以万华岩溶洞内为盛，我们先来看一组权威的空气检测报告：

twelve thousand four hundred and twenty

A fascinating number

       According to CCTV 13's live news room, the National Health Commission announced that China's per capita life expectancy will reach 77 years in 2020, an increase of 43 years from 35 years in the early days of the founding of the people's Republic of China. This has a direct and important role in the continuous improvement of China's economic development, the continuous improvement of medical technology, the improvement of people's living conditions and the improvement of ecological environment. Among them, the ecological and environmental factors are particularly prominent. For example, many people with superior economic conditions went to Qinling, Taishan, Bama, Erhai and other places to build villas. Although some were demolished due to illegal construction, it reflects people's pursuit of a good ecological environment from another side. There are also many people who always try their best to find time to go to some well-known ecological villa, or ordinary farm, or rent a farm house for a long time or a short time, stay away from the complexity and noise of the city, release the pressure brought by work, enjoy the green mountains and waters of nature and breathe the fresh and clean air in the wild, so as to achieve the purpose of health.

       To achieve the purpose of health, air is a very important factor, and the number of air negative ions greatly affects the air quality, which has become an important index to measure the air quality. Wanhuayan scenic spot has such an excellent air environment, especially in wanhuayan karst cave. Let's take a look at a group of authoritative air detection reports:

一般而言，空气负离子对人体的保健作用和辅助疗效大小与它的浓度有关，当空气负离子浓度达到700个/cm3以上时，会有益于人体健康，达到1000个/cm3以上时，对霉素菌的生长有抑制的作用，达到10000个/cm3以上时就具备了治疗效能。很显然，表中各个点的空气负离子含量检测结果均已远远超过700个/cm3这个下限，具备极其优良的保健作用和辅助疗效作用。

Generally speaking, the health care effect and auxiliary curative effect of air negative ions on human body are related to its concentration. When the concentration of air negative ions reaches more than 700 / cm3, it will be beneficial to human health. When it reaches more than 1000 / cm3, it will inhibit the growth of Mycobacterium. When it reaches more than 10000 / cm3, it will have therapeutic effect. Obviously, the detection results of air anion content at each point in the table have far exceeded the lower limit of 700 / cm3, which has extremely excellent health care and auxiliary curative effect.

“12420”，如此高的含量，国内外都是非常罕见的！

那么，空气负离子对人类有哪些作用呢？

它的作用主要有：（1）清洁空气，改善环境——降尘、杀菌、除臭、净化空气；（2）医疗保健作用——改善肺功能，改善呼吸系统绒毛的清洁工作效率，降低血脂，增强心肌功能，镇痛、改善睡眠等作用；（3）激活肌体多种酶，中和人体的酸性或带过多正离子的细胞，促进人体的新陈代谢，具有较高的活性，有很强的氧化还原作用（杀菌、愈合伤口），增强免疫系统功能、治疗支气管哮喘以及排毒等作用。

那洞内这么高的空气负离子含量是怎么产生的呢？

空气负离子产生有三大机理：一是大气分子受紫外线、宇宙射线、放射性物质、雷电、风暴等因素影响发生电离，产生负离子；二是水的喷筒效应（也叫Lenard效应）使水分子裂解，瀑布的冲击、海浪的推卷等，水微粒互相碰撞，以及洞顶滴水使水分子裂解产生大量的负离子；三是森林的树冠、枝叶的尖端放电以及绿色植物的光合作用形成的光电效应也会促使空气电解，产生负离子。

万华岩洞内空气负离子的产生就属于第二种机理，一方面万华岩的地下河落差很大，流速湍急；另一方面洞内空气湿度很大，洞顶有大量水滴滴落；另外，洞顶岩层有许多裂缝，大量水从裂缝渗出，形成许多小瀑布。这些特定条件都为空气负离子的产生创造了极为有利的条件，洞内如此高的空气负离子含量也就不足为奇了。

同时，万华岩洞穴系统还具有医疗的作用，虽然机理在许多方面还不完全清楚，但特殊的洞穴环境至少在减少致病或过敏的环境因素、病原体及过滤污染物及气候波动等方面发挥了其它场所无法代替的作用，至少在下列几方面经临床记录而被证实有生物学上有利变化：

·气喘型的窒息性事件将变得稀少和减轻；

·感冒、粘膜炎偶发事件将变得稀少和减轻；

·易于移开积聚起的支气管分泌物；

·呼吸强度的加深；

·心理状态的改善。

对慢性呼吸道疾病的医疗有明显的效果，深受病患者和专家的青睐。

现在网上流行一句这样的话：“我好难啊！”，高强度、快节奏的工作使我们的生活变得压力山大，何不找个机会、挤出点时间放飞一下自己，抛开烦恼、远离喧嚣，去看看绿水青山，呼吸呼吸清新洁净的空气，把自己融入大自然的怀抱。来吧！朋友，万华岩正敞开胸怀欢迎您的到来！

       So, what are the effects of air negative ions on human beings?

       Its main functions are: (1) clean the air and improve the environment - dust reduction, sterilization, deodorization and air purification; (2) Medical and health care function - improve lung function, improve the cleaning efficiency of respiratory system villi, reduce blood lipid, enhance myocardial function, relieve pain, improve sleep, etc; (3) Activate a variety of enzymes in the body, neutralize acidic or cells with too many positive ions in the human body, promote human metabolism, have high activity, have strong redox effect (sterilization, wound healing), enhance the function of the immune system, treat bronchial asthma and detoxify.

       How did such a high content of air negative ions in the cave come about?

       There are three major mechanisms for the generation of air negative ions: first, atmospheric molecules are ionized and produce negative ions under the influence of ultraviolet rays, cosmic rays, radioactive substances, lightning, storms and other factors; Second, the water jet effect (also known as Lenard effect) causes the water molecules to crack, the impact of waterfalls, the rolling of waves, the collision of water particles with each other, and the dripping water from the cave top causes the water molecules to crack and produce a large number of negative ions; Third, the tip discharge of forest canopy, branches and leaves and the photoelectric effect formed by the photosynthesis of green plants will also promote air electrolysis and produce negative ions.

       The generation of air negative ions in Wanhua cave belongs to the second mechanism. On the one hand, the underground river of Wanhua cave has a large drop and rapid velocity; On the other hand, the air humidity in the cave is very high, and there are a lot of water drops on the top of the cave; In addition, there are many cracks in the rock stratum at the top of the tunnel, and a large amount of water seeps from the cracks to form many small waterfalls. These specific conditions have created extremely favorable conditions for the generation of air negative ions. It is not surprising that there is such a high content of air negative ions in the cave.

       At the same time, wanhuayan cave system also plays a medical role. Although the mechanism is not completely clear in many aspects, the special cave environment plays an irreplaceable role in reducing pathogenic or allergic environmental factors, pathogens, filtering pollutants and climate fluctuations, Biologically favorable changes have been confirmed by clinical records in at least the following aspects:

       ·Asthmatic asphyxiating events will become rare and alleviated;

       ·The incidences of cold and mucositis will become rare and alleviated;

       ·Easy to remove accumulated bronchial secretions;

       ·Deepening of respiratory intensity;

       ·Improvement of psychological state.

       It has obvious effect on the treatment of chronic respiratory diseases and is favored by patients and experts.

       Now there is a popular saying on the Internet: "it's so difficult for me!" high-intensity and fast-paced work makes our life stressful. Why not find an opportunity and squeeze out some time to fly yourself, put aside your troubles and stay away from the noise, go to see the green waters and mountains, breathe the fresh and clean air, and integrate yourself into the embrace of nature. Come on! My friend, wanhuayan is opening up to welcome you!
