Freeradicals is a research hotspot in life sciences. In 1956, Harman of the United States introduced the concept of free radicals in radiation chemistry into the biological field, and proposed the famous freeradicals theory, reactive oxygen species, ros is the most common free radical in the body. The free radicals of the human body are mainly oxygen free radicals. Excessive free radicals induce the body's oxidation reaction, which can damage the body's tissues and cells, leading to aging. So Harman proposed the famous freeradicals theory of aging. Oxidative stress causes oxidative damage of biological molecules, causing the production of damage-associated molecular patterns (DAMPS) and the release of cytokines. 1. Free radicals and aging Under normal circumstances, the generation and removal of free radicals in cells is in a dynamic equilibrium state. With age, this balance is gradually destroyed. As a result, the concentration of free radicals exceeds the "threshold", and chain free radical reactions make DNA, protein, especially polyunsaturated fatty acids and other macromolecular substances are denatured and cross-linked, which damages organelles, cell membranes and other structures, leading to oxidative stress damage to the organism, and eventually aging and death. Therefore, Harman proposed the theory of free radical aging, which can be summarized as the intensification of the contradiction between the excess of ROS produced by mitochondria and the weakening of ROS defense capabilities, which ultimately leads to aging. In 1994, Barja et al. pointed out that the less ROS produced per unit of oxygen consumption, the longer the life span. The use of drugs or nutrients, calorie restriction (CR), and exercise are effective measures to delay aging. They can all increase antioxidant capacity and reduce the production of ROS, and become a powerful support for the theory of free radical aging. 2. Inflammation and aging As we age, a chronic progressive increase in pro-inflammatory status appears in the body. Franceschi and others named this phenomenon inflammatory aging for the first time. The English term corresponding to inflammatory aging was first inflann-aging, and later literature appeared inflammaging, inflamm-age-ing and inflammageing. Xia Shijin and others first translated "inflamm-aging" into the Chinese term "inflammatory aging", and pioneered a series of studies on inflammatory aging mechanisms and interventions in China. Inflammatory aging is closely related to a variety of senile diseases. The pro-inflammatory factors and anti-inflammatory factors in the elderly show ups and downs, and finally manifested as excessive pro-inflammatory response and imbalance of inflammatory homeostasis leading to inflammatory aging. Salviolii and other studies have shown that: pro-inflammatory cytokines play an important role in the body's inflammatory senescence caused by chronic inflammation.

The use of hydrogen for health care has become an inevitable trend. Many people who focus on health care have benefited. Many manufacturers have seen the prospect of hydrogen and customer needs. At present, many domestic manufacturers are developing and producing hydrogen-rich products. There are many types of hydrogen-rich water cups, and consumers are confused. How to choose? The editor hereby reminds consumers and friends that you must not be greedy for cheap when buying hydrogen-rich water cups. Some sellers directly say that they are cheap. Simple electrolyzed hydrogen-rich water cups without SPE membrane electrolysis are “poisonous cups”. This is also reasonable. Drinking hydrogen-rich water requires a lot of drinking. It is common to drink it for months. The influence of a little bit of harmful substances should not be underestimated. ◆1. Why is the hydrogen-rich water cup that produces ozone and residual chlorine without a membrane is a poisonous cup?       Without the use of hydrogen-rich ion membrane cups, ozone and residual chlorine during electrolysis are very serious. Many manufacturers did not use SPE film, in order to eliminate residual chlorine, they made a white particle stick in the water cup and used chemical neutralization to eliminate residual chlorine in the water. However, this method may not be safe. Who knows the chemical and electrolysis What new toxic substances will be produced by the chemical reaction of the (hydrogen, oxygen, ozone) and other mineral substances in the effluent?. ◆2. How serious is the harm of ozone and residual chlorine?       Ozone and residual chlorine are very harmful to human health. Long-term use will cause chronic poisoning, leading to the production of large amounts of free radicals in the body and accelerating the speed of human aging. The main symptoms are rhinitis, chronic bronchitis, emphysema, liver cirrhosis, atherosclerosis, and even cancer. After the chlorine is heated, the organic humus in the water produces carcinogens such as chloroform, which increases the carcinogens in our body by 3-4 times ◆4. How to choose a safe hydrogen-rich water cup       At present, the hydrogen-rich water cups on the market are very chaotic, with a large number of poison cups, and long-term use of poison cups is harmful to health. How to choose?       ◆ Use plastic cups, food-grade ones.       ◆ The electrolysis circle must be made of high-purity titanium-platinum gold. Only the titanium-platinum electrode has no heavy metal precipitation.       ◆ Choose a water cup with a hydrogen-oxygen separation SPE membrane, because it can block ozone and residual chlorine and remove it from another hole. The hydrogen-rich water cups produced by our company use SPE technology to produce hydrogen. The materials used in the electrolysis ring are titanium alloy electrode sheets. The cup body uses food-grade PCS. It is our beli...

Ion detox foot bath is an all-round energy foot spa. This product is widely used in ordinary families in developed countries in Europe and America. Its purpose is to enjoy the spa, like hot springs, exercise, and qi training. , Its effect can make your body feel relaxed and more energetic after soaking. The natural energy of water will excrete impurities and waste from the body, just like drinking more water is beneficial to the body, a long-term brand new health care method. Humans are made of cells, and the cell membrane is a barrier to prevent extracellular substances from freely entering the cell. It ensures the relative stability of the cell's internal environment and enables various biochemical reactions to run in an orderly manner. However, cells must exchange information, materials and energy with the surrounding environment in order to perform specific physiological functions. Therefore, cells must have a set of material transport system to obtain required materials and discharge metabolic waste. It is estimated that proteins related to material transport on the cell membrane account for 15-30% of the proteins encoded by nuclear genes. Cells use energy for material transport. Up to two-thirds of the total energy consumed by cells. Efficacy 1: The cooperation of ion detoxification foot bath and cell membrane brings effect: because the diameter of heavy metals, grease and tar in toxins is smaller than the inner diameter of human pore sweat gland ducts, under the action of negative potential, toxins are successfully driven out of the body through sweat pores . Efficacy 2: Negative potential can also neutralize the positive potential of toxins in the body, protect the human body from the attack of toxins, and avoid the harm of toxins to the body. Efficacy 3: Under the action of the biological energy field, the hydrogen bond between the water molecules is opened, and the water of the original large molecular clusters becomes the water of small molecular clusters, and its solubility and penetration are significantly improved, and the water of small molecular clusters is effective After penetrating into the human body through the skin, it can effectively penetrate into cells on the one hand to dissolve the toxins deposited in the cells, on the other hand, it can dissolve fat and release the toxins wrapped in fat. And through the blood circulation, toxins are carried to the capillaries of the feet and discharged from the body through the pores to achieve the detoxification effect. Efficacy 4: Ion detox foot bath realizes the TCM purpose of "pain is not painful, and pain is unreasonable". Traditional Chinese medicine pays attention to the circulation of qi and blood, and the meridians are unobstructed. The "elimination of toxin" in traditional Chinese medicine means "soothing meridians and activating collaterals, opening up channels", and let it be excreted. The ion energy meter can restore cell potential to normal, reduce local tissue resistance...

  The average life expectancy of Japanese women is about 85 years, ranking first in the world.    The secret to its longevity is that in addition to effective control in diet, it also attaches great importance to drinking water.   In 2007, Professor Naruto Ota of the Japanese Medical University discovered that hydrogen molecules can scavenge free radicals in the human body, and have a good therapeutic effect on aging and many chronic diseases caused by free radicals. This discovery officially opened the prelude to the research on the biological effects of hydrogen molecules and the rise of hydrogen-rich related industries. Therefore, Japan became the first country to develop hydrogen water and put it on the market. Hydrogen-rich water plays a special role in medical treatment and health, and it has been widely accepted by Japan and developed countries.   Hydrogen rich water started late in other countries and only landed in China for the first time in 2013. In recent years, the prevalence of chronic diseases such as diabetes, hypertension, malignant tumors, and cardiovascular and cerebrovascular diseases has increased dramatically worldwide.    At present, there are 860 million people suffering from hypertension in the world, more than 500 million people with diabetes, and a large number of patients with cardiovascular and cerebrovascular diseases and chronic non-obstructive pulmonary diseases. The death toll from chronic diseases accounted for 86.6% of the total death toll and has become the number one killer threatening people’s health. In terms of anti-aging, according to research in beauty salons, 84.4% of people go to beauty salons to delay aging. It can be seen that there is a huge market demand for hydrogen-rich water, and it is expected that the world's hydrogen-rich water market will exceed 10 billion yuan in the future.
