What is UV light and why is it bad for You?
When people mention UV light, they often only talk about its damaging qualities – but we benefit from UV radiation as well. UV light impacts numerous metabolic processes in people, plants and animals. But our digital way of life means we’re spending more time indoors and thus don’t see the daylight as much.
What are the benefits of placing UV lighting in a coil system?
Placing UV lighting within the coil system has the added benefit of destroying the mold and fungi that grow on coils and restrict airflow, and this upgrade can restore coils to installation levels of efficiency and significantly increase airflow.
What are the long-term effects of UV radiation?
They can trigger acute medium- and long-term damage: Enjoyed in moderation, UV-A and UV-B rays tan the skin, but high doses can cause redness, rashes, allergies or sunburn, for instance on the eyelids. UV-B radiation can cause acute photokeratitis (AKA UV keratitis), a type of damage to the cornea.

What color of light emitting diode is used to improve acne?
Blue LED light is most often used to treat acne. It may do this by reducing activity in the sebaceous glands, so they produce less of the oil that can plug the hair follicles, leading to acne. Blue light may also kill acne-causing bacteria known as Cutibacterium acnes.
What is a beneficial effect of a direct high frequency treatment?
What is High Frequency good for? High frequency increases oxygen to the skin, improving the overall texture, tone, and glow and helps to treat acne problems. All of this promotes collagen stimulation and elastin production, providing a firmer and more youthful appearance.
Which of the following ultraviolet rays are the longest and most frequently used in tanning booths?
UVAUVA (315-400 nm): These are the longest wavelengths and account for approximately 90 percent of the radiation that reaches the Earth's surface. UVA rays can cause sunburns and skin aging among other health risks. Most tanning equipment emits UVA rays because they are less likely to cause sunburn than UVB rays.
What are the benefits from using Tesla high frequency current?
The safe, gentle of the high frequency current infuses the skin with oxygen and has been shown to enhance blood circulation, increase collagen and elastin production, eliminate toxins and acne-causing bacteria, encourage lymphatic drainage, exfoliate dead skin cells and improve skin care product absorption.

Why is UVC used in disinfectant?
UVC radiation also destroys cells, which is why it is used in artificial disinfectant. Yet even if UV-C radiation were to cause damage, you don’t need to take any special precautions because the ozone layer absorbs it completely – even in those areas where the ozone layer has been damaged.
How sensitive are eyes to UV light?
When people think of sun protection, the first thing that springs to mind is their skin. But our eyes are also sensitive to UV radiation – not only when the sun is shining but in the shade, too. Not only at noon, but all day, every day. Even on a cloudy day, UV radiation can be as high as 70 to 75 percent on the ground due to reflection and dispersion. 2 Water, for instance, reflects up to 20 percent of UV radiation, fresh snow roughly 88 percent, sand up to 25 percent and a concrete road around 12 percent. 3
Why does sunscreen cause acne?
While the exact cause is unknown, we do know that the effect of UV radiation on greasy sunscreen can cause the skin’s oil glands to become inflamed. This reaction will lead to the aforementioned symptoms.
Why is summer important?
Summer means fun in the sun! For many people, this is the best time of year. They head out to enjoy the great weather, spending time at sidewalk cafés, parks and pools. When people mention UV light, they often only talk about its damaging qualities – but we benefit from UV radiation in different ways. UV light impacts numerous metabolic processes in people, plants and animals. But our digital way of life means we’re spending more time indoors and thus don’t see the daylight all that much. So it’s even more important to step outside more often and take part in outdoor activities to make ourselves feel good and stay healthy. All the same, we should ensure that we are sufficiently protected from the sun – that applies to our skin as much as it does to our eyes. To ensure you’re fully protected, we recommend wearing either a high-quality pair of sunglasses or clear lenses with an integrated UV filter up to 400 nm. 1 That’s because UV radiation can damage our eyes in a number of ways – but there are great ways to protect ourselves, too.
What is the term for damage to the cornea caused by UV radiation?
These include conjunctivitis and photokeratitis (a.k.a. ultraviolet keratitis). These terms refer to damage to the cornea caused by strong UV radiation that you find up in the mountains. In continuous intense light, we run the risk of the eye’s lens becoming cloudy, which can lead to premature cataract.
How much UV radiation is on the ground?
Not only at noon, but all day, every day. Even on a cloudy day, UV radiation can be as high as 70 to 75 percent on the ground due to reflection and dispersion. 2 Water, for instance, reflects up to 20 percent of UV radiation, fresh snow roughly 88 percent, sand up to 25 percent and a concrete road around 12 percent. 3.

In fact, 5–10 percent of all skin cancer cases involve the eyes. 5 To ensure that this sensitive area is protected from UV radiation, we recommend wearing both sunglasses and normal glasses with full UV protection up to 400 nm.
Why is UV C used in disinfectant?
UV-C radiation also destroys cells, which is why it is used in artificial disinfectant. But you don’t need to take any special precautions against UV-C radiation, because the ozone layer absorbs it completely – even in those areas where the ozone layer has been damaged.

What are the long term effects of tanning?
Common long-term effects of excessive tanning are expanded pores and blood vessels, damage to the connective tissue, blackheads and dry skin. In addition to sunburn and redness, UV light can cause a variety of symptoms that are often collectively referred to as a “sun allergy.”.
Why is UV light important?
Ultraviolet light is a misunderstood and under-utilized tool for improving indoor air quality. There are various reasons to take advantage of the possibilities that UV lighting provides. It is used in hospitals and research labs to sterilize equipment and rooms, and scientists have yet to find even a superbug that is resistant to UV-C rays.
Why is UV light used in hospitals?
Ultraviolet light has been used to sterilize equipment in hospitals and research labs since the 1930s. In the 1990s there was a push to use UV-C to improve indoor air quality by reducing the microbial build-up within HVAC coils. In 2013, the Centers for Disease Control and Prevention (CDC) participated in a study on eliminating some “super bugs” common in hospital rooms using a disinfection system featuring germicidal UV-C light.
Why do HVAC units need UV lights?
Placing UV lighting within the coil system has the added benefit of destroying the mold and fungi that grow on coils and restrict airflow, and this upgrade can restore coils to installation levels of efficiency and significantly increase airflow. An HVAC/R unit augmented with UV-C will last longer and require less maintenance, because it does not have to work as hard to move air through the coils.
What can UV light do to a HVAC system?
UV-C light at appropriate dosages can eliminate many types of fungi, molds, bacteria, viruses as well as other microorganisms. With proper light placement, all pathogens can be eliminated from air passing through an HVAC/R unit.
Does UV light remove fungal contamination?
Studies have been done by Duke University Medical Center and the National Center for Biotechnology Information to determine whether UV light actually helps to remove fungal contamination and other harmful airborne particles from the air. The results were quite positive. In both studies, UV-C rays led to significant reductions in contamination.
How far away from the client's face should infrared light be placed?
An infrared light must be placed at least 30 inches from the client's face during a facial.
Which electrode will create more and smaller bubbles than the positive electrode?
The negative electrode will create more and smaller bubbles than will the positive electrode.
What is the purpose of an electrode?
A current conductor called an electrode is used to bring the current from the appliance to the client's skin.
