Why avoid ozone sanitization

What is mainly proposed today to carry out a sanitation is the ozone method. It should be emphasized that this type of sanitization has immediate effectiveness for the air and surfaces, but that within a few hours it becomes ineffective due to the simple fact that the area in question is constantly recontaminated. The only effective sanitation is constant sanitation 24 hours a day, 7 days a week. Another contraindication is due to the fact that the environment to be sanitized must be left by the occupants for the entire duration of the treatment. Unfortunately, once they have returned to their home or company, they are subjected to the inhalation of Ozone particles that are seriously harmful to our body.

Researchers have been studying the effects of ozone for several years; to date, they have shown that ozone causes various types of effects on the respiratory tract:

Ozone can irritate the respiratory system.

When this happens you may begin to cough, feel a sense of irritation in the throat and lungs. These symptoms can continue for a few hours after exposure to high ozone levels and can even be painful.

Ozone can reduce lung function.

It means that the amount of air you can breathe decreases. Ozone can make it harder to breathe deeply, and if you are doing strenuous activity outdoors you find that you are breathing faster and less deeply than you normally would.

Ozone can aggravate asthma and other respiratory conditions.

When ozone levels are high, asthmatics become more likely to have a seizure, which requires the use of drugs or a doctor's visit. In fact, ozone makes asthmatics more sensitive to the allergens that trigger the attack. Furthermore, asthmatics are more sensitive to the reduction of lung function and to the irritation that ozone causes in the respiratory system. Ozone can aggravate chronic lung diseases such as emphysema and bronchitis.

Ozone can cause inflammation of the thin layer of cells that lines the respiratory tract.

This effect has been compared to that of a sunburn on the skin. Damage occurs on the cells and in a few days the damaged ones are replaced and there is an exfoliation as for the skin after a sunburn. If it happens frequently, there can be long-term damage, with a reduction in the quality of life.

Other health effects

Some animal studies have suggested that ozone may reduce the immune system's ability to fight infections of the respiratory tree.

Most of these effects are considered to be short-term and cease once individuals are no longer exposed to high levels of ozone. However, there is concern that damage from repeated short-term exposure can lead to permanent changes in the lung. For example, repeated exposure to ozone in the developing lungs of children can lead to decreased lung function once they are adults. Furthermore, exposure to ozone can accelerate the natural aging process of lung function.
