If UV lights kill bacteria, why don’t we use them everywhere? Here’s the scientific answer to the question

During seasonal transitions stuffy nose, sore throat Does struggling with an endless cough sound familiar to you?

If your answer is yes, you are not alone! Well, it is UV lamps. to end the nightmare What kind of miracle can he create?

How do UV lamps kill bacteria and viruses?

UV light

Ultraviolet (UV) light has the ability to kill bacteria and viruses. Arthur Downes and Thomas Blunt in 1877; from sunlight, stops the growth of bacteria and found that it completely killed pathogens in high doses.

This effect is caused by UV radiation By damaging DNA and RNA It can be explained by preventing the proliferation of microorganisms.

What is Far-UV and why is it safer?

A new type of UV light, known as Far-UV, differs from older UV lamps. shorter wavelength and is less harmful to human skin/eyes.

from Columbia University. David Brenner and his team found that far-UV lamps are effective in killing viruses and bacteria is not harmful to human health He has done a lot of research that shows that

Why then is the use of UV lamps not widespread?

One of the biggest problems with UV lamps is that they break down oxygen molecules, which creates ozone. Ozone, respiratory diseases It is a harmful gas that can cause

In addition, UV lamps interact with volatile organic compounds. harmful particles can make. More research and pilot projects are needed for widespread use of Far-UV technology.

For example such as oil platforms The effects of far-UV lamps can be studied in enclosed spaces with high human traffic. Such projects are crucial for testing the effectiveness and safety of far-UV in the real world.
