Many friends' daily life is inseparable from the hair dryer. Traditional hair dryers can easily damage the structure of the hair, making hair crepe, and negative ion hair dryers use negative ion conversion technology to avoid the shortcomings of ordinary hair dryers. What is the role of the negative ion hair dryer ? Xiaobian takes everyone to see.
The role of negative ion hair dryer :
The negative ion hair dryer mainly contains a negative ion generator and a semiconductor refrigeration device, so that when the hair dryer is working, negatively charged ion particles (generated by a negative ion generator) and water vapor particles (generated by a semiconductor refrigeration device) can be generated. Neutralizes the positive charge that is often found in hair, smoothing out messy hair, making it smooth, and eliminating static electricity. Make hair smoother and easier to comb, and the shape is more ideal.
Negative ions have a health effect. In different regions, the number of negative ions present in the air is quite large. It has been measured. According to the number of negative ions contained in the cubic centimeter of air, there are about 1,000 in the countryside and 4,000 in the seashore. More than 5000. Because of the high content of negative ions in the air in these places, people feel energetic. However, in some densely populated cities, the concentration of negative ions is relatively low due to the serious air pollution.
There are also environmental departments that have tested. In the city, there are hundreds of negative ions per cubic centimeter, and there are fewer indoors, no more than 1000! Especially in the TV and computer, there is almost no negative ion, long-term Learning and working in this kind of environment are often fatigued and not conducive to health.
Why do negative ions have a health effect? Medical experts have considered the following three reasons through research.
First, in a living body, each cell is like a miniature battery with a potential difference of 50 to 90 millivolts inside and outside the membrane. It is the constant charge and discharge effect of these "batteries". The body's nervous system can send signals such as sight and hearing to the brain, or transmit instructions from the brain to various organs of the body. The electrical activity of the body tissue needs to be supplemented by the constant supplementation of negative ions. Once the organism is not supplemented by negative ions, it will affect normal physiological activities, resulting in chest tightness, dizziness, and even illness.
Secondly, since the virus that attacks human cells usually has a negative charge, if the human cells also carry a negative charge, they will be repelled by the same sex. The virus loses its ability to attack live cells.
Finally, the negative ions can also enter the lungs through breathing, and directly stimulate the tissues of the human body, as well as the interaction between nerve reflexes and body fluids, and produce a neutralizing physiological health effect on the human body.
In general, the role of the negative ion hair dryer is to make the hair texture good, no static electricity, and not easy to deform. Negative ion hair dryers are relatively high-end, and I hope that when you blow your hair, you should give priority to ways that are more beneficial to your health.
