However, the amount of SOD contained in human body will decrease with age. Glacier water can promote the activity of enzymes in the body, reaching several times or even ten times that of ordinary water. It can enhance the immunity of the body and improve the activity of SOD enzyme in the body. Experiments show that drinking glacier water can increase SOD activity in vivo by 5 to 10 times. Effectively remove acidic waste from blood, prevent allergic diseases, effectively improve internal environment, keep skin and cells young and healthy, and delay human aging. During the period of 1965, Russian scientists fed tap water and melted ice and snow water to small animals, and the deuterium content was 25% lower than normal. After a period of time, comparing the physiological differences between the two groups of animals, it was found that the animals fed with melted ice and snow water grew faster and more energetic than the other group. These works were confirmed by scientists all over the world in the next 50 years.
Lanzhou Institute of Glacier and Frozen Soil, Chinese Academy of Sciences has also done a lot of scientific experiments. They chose glacier water, tap water and yellow river water for wheat experiments. As a result, the wheat plants with glacier water are the tallest, followed by tap water and yellow river water, and the height of each plant is only half of that of glacier water. People near the Qinghai-Tibet Plateau soaked cucumber and radish seeds in ice and snow water respectively, and finally found that the seed yield soaked in ice and snow water was much higher than that soaked in ordinary water, with cucumber increasing by 23% and radish increasing by 56%. As early as ancient times, people realized the role of glacial water. The forty-first chapter of China's classic Dream of Red Mansions records that Jia Baoyu was tasting tea in Cui 'an, and Miao Yu, the abbot of the monastery, entertained Jia Baoyu with tea made of melted ice and snow five years ago, so that he could taste it carefully. The fruit was very light and pure and appreciated it very much.
Tea must be born in water. The ancients divided the water content of tea into "plum, orchid, bamboo and chrysanthemum". Among them, "the water of plums" is a sacred product in water that real tea drinkers can meet but can't ask for; Glacier water is a rare natural ultra-light water in the world, and its main feature is that the content of deuterium (Dao) in water is lower than that of ordinary drinking water. There are three isotopes of hydrogen, deuterium and tritium. The lower the deuterium content, the smaller the weight of water, so it is also called ultra-light water.
Deuterium (Dao) in water will accumulate after entering human body, which will break, distort and mutate the genetic information of DNA double helix structure, while radiation will change the genetic information of DNA. The deuterium content in glacier water (ultra-light water) is extremely low, which can effectively protect the integrity of DNA information.
According to foreign media reports, Yuri Snyak, a professor at the Russian Institute of Medicine and Biology, announced at a meeting held to commemorate the successful development of the life support system for space flight that the research showed that "light water" with a very small amount of heavier isotopes without or containing deuterium, tritium and oxygen has a series of very beneficial biological characteristics. A series of experiments conducted by scientists in this institute have confirmed that "light water" can effectively resist radiation: those mice that have suffered too much radiation can still survive for a long time after drinking "light water".
