Ultraviolet heaters: myth or reality

Ultraviolet heaters, according to their creators, are supposedly capable of sanitizing the premises, and heating it, and charging the human body with vitamin D. However, this is nothing more than an advertising duck, through which sellers of technology are trying to attract new buyers.

The main purpose of the ultraviolet - the destruction of pathogenic bacteria. Manufacturers of technology, having learned about the positive properties of ultraviolet, began to design devices, the purpose of which, first of all, is to disinfect, and then - to heat the surrounding objects and air. Consider the features of devices in more detail.

The advantages and disadvantages of ultraviolet radiation

Ultraviolet, depending on the wavelength, has a different effect on living beings. So, shortwave rays, also called near ultraviolet, are the most dangerous, they can have a destructive effect. But fortunately, the ozone layer of the Earth does not let them through, thereby saving us from such a destructive impact. Only medium-sized waves reach us in small quantities, and almost 90% of UV rays are long-wavelengths.

Ultraviolet harmful effect on microorganisms, bacteria, germs, fungi. These waves are able to penetrate their DNA and destroy the division responsible for reproduction.

Thus, under the action of ultraviolet radiation die entire colonies of pathogens. Fortunately, the skin of a person prevents such a quiet passage of ultraviolet radiation to DNA. Therefore, people, as well as animals (as protection serves as wool) and birds (feathers) are not so strongly susceptible to CC radiation.

It is worth noting that it is thanks to ultraviolet that our skin acquires the very desired bronze tan.Long stay under these invisible rays can provoke negative changes in the skin that can lead to serious diseases. Short-term, but strong exposure to ultraviolet radiation, for example, if you look at the light emanating from a germicidal lamp, on welding, can damage your eyes and provoke a retinal burn.

It is noteworthy that ultraviolet light can accumulate in the body in the form of free radicalsthat damage DNA, RNA, thereby provoking the occurrence of various eye diseases, such as cataracts, retinal breaks, myopia, and farsightedness.

Despite the negative effects of the influence of ultraviolet radiation, it is necessary to note its positive qualities:

1. Bacteriological disinfection of surfaces.
2. Long-wave ultraviolet contributes to the accumulation of vitamins in plants, namely vitamin C, stimulates photosynthetic processes and maintains a healthy state of pigment in the leaves.
3. Vitamin D reduces the body's resistance to insulin, maintains blood sugar levels and stabilizes mood.This very vitamin begins to be produced only when UV rays fall on our skin.
4. A good mood that rises as soon as the sun begins to shine brighter.

Scientists and manufacturers of a number of household appliances and medical devices, knowing the dangers and benefits of ultraviolet radiation, are developing new types of devices that should have a positive effect on people during their work.

Devices whose principle of operation is based on ultraviolet

Today, there are many devices called ultraviolet heaters. But they are not. Most of them are various lamps of various designs. They are used in medical institutions, beauty salons, with the help of them carry out disinfecting procedures:

• sterilizers - heaters;
• bactericidal lamp;
• dryer for shoes;
• towel heater.

Germicidal lamp

Many probably remember that at home they were treated at home with the help of blue lights. With catarrhal diseases of ENT organs, “warming up” procedures were carried out, lasting several minutes.Their work is based on disinfection, such as the nasal mucosa with a cold, with the effect of heating. With the combination of heat and ultraviolet recovery of the patient occurs many times faster.

Shoe dryer

The device is a block equipped with a heating element and a lamp with ultraviolet radiation built into the office of the device. Such devices make our life and life easier, thanks to them you can:

• dry shoes quickly;
• destroy pathogenic bacteria, fungi and microbes,
• get rid of unpleasant smell;
• keep the original shape of the shoe.

Heater Sterilizers

Such equipment is used in beauty salons, hairdressing salons to disinfect various devices: scissors, combs, files used in this area, but which cannot be subjected to other methods of cleaning, such as boiling. Such equipment combines the functions of a heater and ultraviolet sterilizer.

Towel Heater

Beauty salons, most spas that care about the health of their customers, sanitize towels using just such heaters.Allowing thereby to use wet towels, compresses, lotions in a number of cosmetological procedures completely disinfected.

Application spectrum

The range of application of ultraviolet heaters is quite wide:

1. In tanning salons where ultraviolet light is used to get a tan. In parallel, disinfection and the fight against all kinds of skin diseases are performed.
2. In hairdressing salons for the sterilization of master tools: scissors, brushes, combs and so on.
3. Ultraviolet heaters are widely used in dental clinics, for example, when installing light-curing fillings. But in this case, it is imperative to protect the eyes, otherwise you can earn a burn of the cornea.
4. In the fight against viruses, pathogenic microbes and bacteria. So, ultraviolet destroys living cells of harmful microorganisms, without affecting their habitat at all. This makes it possible to disinfect water, rooms, household items, sterilize equipment.

Conclusion

As we can see, ultraviolet heaters are not used in everyday life for space heating. They simply do not exist.there is infrared heaters, which purpose, first of all, is heating of the surfaces surrounding them and objects.

Ultraviolet in nature has other options, one of which is disinfection of premises, household items, medical and salon tools.

Under the action of ultraviolet rays, our body is saturated with vitamin D. Using this radiation, for example, in a bactericidal lamp, which has both a heating effect and disinfection, we can speed up the healing process for diseases of the ear (otitis), runny nose, or sore throat.
