Wipe out bacteria and viruses with the sun’s UV Rays

If you’ve ever used any kind of sunscreen before, you’re probably familiar with the phrase: “protects your skin from harmful UV rays.”

Indeed, UV rays have become almost synonymous with the word ‘harmful’. Many people have become so accustomed to thinking about them as something bad that they do everything they can to block them out. That’s why UV blocking window tints, anti-UV blinds or curtains, and UV resistant glass have become so popular in modern times.

However, recent studies have come to light suggesting that UV rays may actually have some good effects, contrary to popular belief.

Sunlight and UV rays

While UV rays are usually associated with sunlight, it’s not actually the only source. Ultraviolet radiation is a form of radiation that is found in sun rays as well as man-made items like tanning beds and light lamps.

For decades, scientists have known that UV light has germicidal benefits. Unfortunately, since UV rays are also considered hazardous to human health, UV light can’t be used in public spaces without sufficient studies. This doesn’t mean, however, that you’ll automatically get cancer if you go out under the sun. After all, too much over a long period of time may be harmful, but a little bit every now and then isn’t going to have any adverse effects.

In fact, studies show that letting a little UV light into your home can actually be quite beneficial for you and your family.

How can UV rays kill bacteria and viruses?

In 2018, a study from the Center for Radiological Research at Columbia University Irving Medical Center found that using overhead lamps that contain UVC light can actually kill both bacteria and viruses and even reduce the instances of influenza outbreaks.

A more recent study conducted by researchers from the University of Oregon attempted to observe the effects of sunlight and UV rays on germs and bacteria indoors. The study made use of 11 identical climate-controlled dollhouse rooms, the only variation being the amount of light that was allowed to go in. Researchers left the rooms undisturbed for 90 days; after which, they collected dust samples to analyze the bacteria that grew inside.

The results were rather astounding. Dark rooms were shown to have the highest percentage of viable bacteria at 12%. Viable bacteria can be defined as bacteria that are still able to live and reproduce. But in rooms where sunlight was allowed to stream into the area, this percentage dropped to 6.8% – an almost 50% decrease. Meanwhile, the percentage dropped further to 6.1% in rooms that had UV rays instead of filtered sunlight.

Using sunlight and UV rays for your home

Do you know what’s even better news? Sunlight doesn’t just kill bacteria and viruses– it can also help improve your mood and make you feel much better in an instant. Trust us, there’s no easier way to prevent illnesses and lift your spirits than simply pulling up your blinds.

Indeed, although UV exposure without protection over various hours can harm our skin, the truth is that UV rays aren’t always a bad thing. With all that said, perhaps it’s time to let some sunlight into your home, don’t you think?
