Hair dryer negative ion health effect

Negative ions have health effects. In different regions, the number of negative ions in the air is quite large. Some people have measured it. According to the number of negative ions contained in the air per cubic centimeter, there are about 1,000 in the countryside, 4,000 on the seashore, and up to fountains and waterfalls. Above 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 serious air pollution.

Some environmental departments have also conducted tests. In cities, there are hundreds of negative ions per cubic centimeter outdoors, and there are even fewer indoors, no more than 1,000! Especially there are almost no negative ions next to TVs and computers. Studying and working in this environment are often fatigued, which is not conducive to health.

Why do negative ions have health effects? Medical experts believe that there are the following three reasons through research.

First of all, in a living body, every cell is like a miniature battery, with a potential difference of 50 to 90 millivolts between the inside and outside of its membrane. It is relying on the continuous charging and discharging of these "batteries". The body's nervous system can transmit visual and auditory signals to the brain, or transmit instructions from the brain to the various organs of the body. The electrical activity of the body's tissues needs to be maintained by the continuous supplementation of negative ions. Once the organism is not supplemented with negative ions, it will affect normal physiological activities, resulting in chest tightness, dizziness, and even illness.

Secondly, because viruses that attack human cells are usually negatively charged, if human cells are also negatively charged, they will repel each other due to the same sex. The virus loses its ability to attack living cells.

Finally, negative ions can also enter the lungs through breathing, and directly stimulate various tissues of the human body, as well as the interaction of nerve reflexes and body fluids, which have a neutralizing physiological health care effect on the human body.
