The Laser Watch is an innovative 3-in-1 device that uses the latest research findings in the field of low-level-laser therapy. It combines acupuncture, local pain management and external blood irradiation and will become your ideal companion-whether at home, at work or on the go.
Areas of application: Red light
Are you also suffering from:
• Stress
• Symptoms of fatigue
• Anxiety
• Tensions
• Rapid heartbeat
• High blood pressure
• Seasonal affective disorder
• Lack of motivation
• Insomnia
These symptoms are often caused by high blood pressure and a low Melatonin and Serotonin level. The red laser is well-known for its ability to enhance cell activity and microcirculation. Furthermore, it activates the immune system by stimulating different leukocyte groups.
Activate Metabolism: Lower Blood Pressure and Improve Blood Flow
Increasing age and an unhealthy lifestyle enhance the possibility that cholesterol and other blood fats build up on vessel walls and thus impair the oxygen and nutrient supply to our organs.
Vasoconstriction leads to metabolic and microcirculation disorders which in turn result in cardiovascular and cerebrovascular diseases, high blood pressure, diabetes, stroke etc.
Laser light activates different enzymes and decomposes redundant fat in the bloodstream. It increases the oxygen amount in the blood, boosts metabolism and enhances the process of lipid peroxidation to reduce cholesterol in the vessels.
Current scientific research of Univ.-Prof. DI DDr. Gerhard Litscher and Mag. pharm. Dr.scient.med. Daniela Litscher shows the effects of the Laser Watch on the cardiovascular system. Pilot studies demonstrated that in healthy test subjects the total heart rate variability (HRV) increases briefly during stimulation with the Laser Watch. Furthermore, it caused an improvement of microcirculation (increase of 15%) during a 20-minute Laser Watch stimulation.

Relieve tensions with the laser pad
Incorrect sitting postures in front of the computer and physical or emotional tensions often cause painful muscle stiffness in the neck and in some cases even lead to tendinitis. Quite often these symptoms are also accompanied by headaches and shoulder pain which radiates into the arms. Whether sport injury or chronical pain-with the laser pad you can now easily treat aching body regions and you will achieve optimal regenerative effects on cellular level. The red light of the laser unfolds its analgesic, anti-inflammatory and reparative effects deep in the tissue layer where it induces various biochemical reactions:
• Blood vessels widen and consequently allow better oxygen transport and blood flow
• Stimulation of the mitochondrial metabolism
• Increase of ATP synthesis
• Stabilization of cell membranes

(1) Atmosphere storage: Modified-atmosphere storage is abbreviated as MA storage. Currently, research and.
The most widely used is small package modified atmosphere storage technology. The MA storage utilizes the respiration of rice and the permeability of the plastic film to regulate the gas composition inside the package. Respiration of rice caused the concentration of CO2 in the bag to rise, and the concentration of O2 decreased. When the rate of CO2 emission and O2 ingestion by the rice is equal to the rate of permeation through the membrane, the partial pressures of CO2 and O2 in the bag no longer change. If the gas condition meets or is close to the gas conditions suitable for storing rice, spontaneous gas transfer will be used. MA.
The key to storage is to choose a suitable fresh-keeping film, as long as the proper fresh-keeping film is selected, the oxygen concentration in the bag can fall below 2% within 2 months, and the CO2 concentration can rise to about 15%. Because of its relatively simple technical operation and relatively low cost. MA technology is effective in suppressing the deterioration of rice quality, and its storage moisture content can be slightly higher than the conventional storage moisture content.
In response to market demand, the National Center for Preservation of Agricultural Products has carried out research on the preservation of rice in terms of moisture control, temperature selection, gas conditioning, and functional membrane compatibility for five small food packaging films. Studies have shown that: Five food films can not only achieve the purpose of storage, and simple operation, low cost [8].
(2) CO2 storage: The rice is sealed and packaged with a plastic film with good gas barrier performance (CO2 permeation < 800cm3/m2d, O2 permeation <200cm3/m2d), and vacuum is first used to recharge 30% or more of CO2 gas. Experiments have shown that the method of storing rice with CO2 at the same time can greatly delay the aging of its quality, and the preservation effect is far superior to that of “double low†and “natural oxygen deficiencyâ€. Especially high moisture content rice CO2 (above 90%) treatment effect is more obvious.
(3) Charge N2 storage: The N2 storage operation method is basically the same as the CO2 storage method except that the N2 concentration is relatively high (95% or more). Experiments have shown that anoxic nitrogen filling has positive significance for maintaining the fresh quality of rice, reducing the loss of rice nutrients, and delaying the aging of rice.
(4) Hypoxic Storage: Adding a deoxidizer in the rice sealed package will make the rice in a low-oxygen (less than 2%) environment, and it will be safe even if the heat engine has a slightly higher moisture content. In addition to the slightly higher fatty acid value of the over-summer rice, the viscosity slightly decreased, but other nutrients remained basically unchanged. In the absence of cryopreservation, anoxic and double-low method is an ideal method for the safety of heat engine rice in summer, and it has low cost and good preservation effect.
Inflatable vacuum packaging, the preservation period significantly longer, up to 6 months. The length of the preservation period is closely related to the type of packaging materials used, gas composition and storage temperature. The effect of fresh CO2 preservation is best. The effect of vacuum and N2 preservation is almost the same. This is because rice has the ability to adsorb CO2, while CO2 can effectively inhibit the respiration and prevent the decomposition and oxidation of fat. When rice absorbs CO2, it is in a hibernation state, so it can effectively delay the aging and thus extend the shelf life.
3.4 Electron Irradiation Anti-mold Storage Electron irradiation storage is performed by electron irradiation of rice produced by an electron accelerator and then stored. After the irradiation, the color of the rice has a certain degree of browning, and makes the rice a little unpleasant smell when it is freshly cooked. The degree of browning increases with the increase of irradiation dose, and there is no influence on the extension of storage time. The mechanism of browning should belong to non-enzymatic reactions. The browning degree of rice samples irradiated by 2.4105 rad doses such as Hu Yushan [9] was lighter. After one year of storage at 30°C, the quality of the rice changed little, and rice consumption was acceptable. If the irradiation dose exceeds 5.0105 rad, although its anti-mildew effect is improved, the degree of browning of rice will increase.
3.5 Chemical Storage Chemical storage is also an important storage method. Experiments have shown that even if a large amount of insects are placed in small package rice, pests can be fumigated and killed within a few days as long as DDVP is added. In addition, there was no live period for more than 3 months. Residue measurement also showed that the tested rice was completely safe. It can be seen that DDVP's slow-release fumigation is safe and effective for pest control of small packaged rice, as long as it is used properly. DDVP may become a commercial fumigant.
4 Prospects for rice storage technology Prospects for high rice storage technology, extending the safe storage period, slowing the deterioration of rice quality and reducing storage costs are the direction of rice storage. Future research on rice storage technology will develop in the following directions.
(1) With the improvement of people's living standards, the storage of rice should be developed in the direction of preservation. The requirements for rice research will be more detailed and deep, and should be based on species selection, species diversity, prenatal management, postpartum harvesting, air drying, storage, rice chemical composition (starch, sugar, lipids, fatty acids, proteins, cell tissues, flavors, etc.) Research is conducted on the relationship between quality (storage quality, cooking quality, food quality, and nutritional quality), and the quality indicators of rice are further clarified to provide a basis for uniform regulations for the national food sector.
(2) With the increase in the level of plastic technology and thin film manufacturing technologies, the production of composite membranes, microporous membranes, and grain-specific membranes will provide a broader perspective for rice storage and preservation technology. Because the respiration intensity of rice is not as strong as that of vegetables, there is a significant difference among varieties, so it is necessary to research and produce a special plastic wrap suitable for different varieties of rice.
(3) With the reduction of the family population and the change of people’s aesthetic point of view, packaging in the process of rice transportation and sales must be “substantially changed and less reformed,†and it should be developed in the direction of diversification, transparency, and aesthetics. .
(4) With the increase in the degree of specialization in science and technology and commodity services, the storage of rice should be specialized in system management, and the consumer groups should be simplistic and reliant. A variety of storage technologies are required to be comprehensively utilized, and the technology should be condensed in bags to facilitate the development of consumption.
