In the midst of the COVID-19 pandemic, UV sanitizers have become a hot topic. They’re marketed as a quick and easy way to kill germs and bacteria on everything such as cell phones, keys, baby toys, and even masks. In this blog post, we will explore the science behind the powers of UV and take a closer look at whether UV sanitizers actually work.
Understanding UV Light
UV stands for ultraviolet, a type of electromagnetic radiation that is invisible to the naked eye. UV light is divided into three categories: UVA (315-400 nm), UVB(280-315 nm), and UVC (100-280 nm). UVA and UVB are the types of UV light that we are most familiar with because they are responsible for tanning, sunburns, and skin cancer. UVC, on the other hand, is the most powerful type of UV light and is capable of killing bacteria and viruses.
The way UVC light works is by damaging the DNA and RNA of bacteria and viruses. This damage prevents them from replicating and ultimately kills them. The effectiveness of UVC light depends on the intensity of the light, the distance between the light source and the object being disinfected, and the duration of the exposure.
While UVC can be effective at killing germs, it can also be harmful if used incorrectly. According to research done by the FDA, shining a UV sanitizer directly on your skin, eyes, or teeth can cause damage. Additionally, some UV sanitizers may not be powerful enough to kill bacteria and viruses, so it is important to do research on the specific device before using it.
How UVC is Used in Hospitals and Airplanes
In hospitals, UVC light is often used in a process known as “terminal cleaning.” This involves using UVC light to disinfect surfaces after a patient has been discharged from a room. The UVC light is typically used in conjunction with other cleaning methods, such as wiping down surfaces with disinfectant, to ensure that the room is as clean as possible.
UVC light is also used in airplanes to disinfect the cabin between flights. This is especially important during the pandemic, as it can help reduce the spread of COVID-19. The UVC light is typically used in a handheld device that can be quickly and easily moved around the cabin to disinfect surfaces. The device is also portable, making it easy to use on multiple flights.
Is A UV Toothbrush Sanitizer Necessary?
Toothbrushes can also be a breeding ground for germs and pathogens. Our mouths are full of bacteria, some of which can be harmful to our health. When we brush our teeth, some of these bacteria can get transferred onto our toothbrushes.
Studies have found that toothbrushes can harbor a variety of bacteria even after rinsing, such as Streptococcus mutans and Porphyromonas gingivalis that cause tooth decay and gum disease as well as E. coli and Staphylococcus aureus, which can cause infections.
Factors such as how often the toothbrush is used, how it is stored, and how it is cleaned can all contribute to the growth of bacteria on the toothbrush. For example, if a toothbrush is left out in a damp environment, such as a bathroom, it can provide an ideal breeding ground for bacteria. Similarly, if a toothbrush is not cleaned properly, bacteria can continue to grow on the bristles.
That’s why dentists recommend replacing your brush head every 3 months or sooner if your bristles look worn out. While not absolutely essential, think of using a UV Sanitizer as a safe and eco-friendly way (as compared to traditional cleaning products) to keep your toothbrush clean and hygienic while removing as many harmful pathogens and bacteria as possible.
Should I Get a UV Sanitizer for my Toothbrush?
With all the benefits mentioned thus far, the answer is pretty obvious. If you’re looking for an affordable product that fulfills its primary function and more, look no further. Retailing at only $26.90, the Mola UV Toothbrush Sanitizer features a Philips UVC bulb (240nm), lasts a month on a 1-hour charge and has an auto 8-hour timer that will make sure your toothbrush is ready when you use it the next time.
