UVB Vs Ultraviolet

The basic component in tanning is ultraviolet light. Ultraviolet light, whether produced by a tanning unit or by the sun, contains two components; UVA and UVB. These are the two types of ultraviolet radiation that are known to negatively effect the skin. UVA has a longer wavelength that causes photoaging and can produce some melanomas. UVB has a shorter wavelength that also causes photoaging and has been implicated in skin cancers. Photoaging is the premature aging or deep wrinkling of skin. Indoor tanning units utilize both forms of light waves to tan a person with a minimized risk of sunburn. Tanning outdoors does not give you this option because the sun omits every type of UV rays, so a person is more likely to burn. A person’s skin epidermis consists of two layers: The germinative layer and the horny layer. Another name for the germinative layer is the “living layer.” And another name for the horny layer is the “dead” layer. When exposed to ultraviolet light, melanocytes in the germinative layer produce melanin that is absorbed by surrounding cells. Melanin is a dark pigment found in the pigment-bearing cells of the skin, and melanocytes are epidermal cells capable of synthesizing melanin. This creates a protective barrier from ultraviolet light reaching deeper into the layers of the skin. The pale pink melanin granules are stored in the core of keratin cells. UVA darkens the melanin,

Have you ever felt the “false sense of security that [you] may not feel under direct sunlight” from a tanning bed (Jeffrey)? Your body relaxes, you feel serene, and you get a golden glow. Some teens strive for this feeling...and the tan. Tanning is the skin's response to injury, according to Arielle Kauvar, M. D. The exposure of UV rays over time can cause skin cancer. Skin cancer is the growth of abnormal growth of skin cells that forms in the tissue of the skin (Skin Cancer). Melanoma, the most dangerous type of skin cancer, can come from UV rays. From 1998- 2008, the number of cases of Melanoma has increased by about

Sharon Miller is the author of this article and is part of FDA. In this article she discusses how each type of uv rays damage the skin and which uv ray is used in tanning beds. This is relevant to my topic because it demonstrates the risk of skin cancer. Many people think tanning gives them a ¨healthy¨ glow, but in reality a tan is a sign on skin damage. UV-B rays burn the top layer of skin resulting in a sunburn in most cases. UV-A rays burn into a deeper layer of the skin causing a rash to appear. Tanning beds emit UV-B rays and UV-A rays, which is why you tend to get a sunburn before turning dark. The UV-B rays cause your body to emit more melanin, which is a pigment that darkens the skin. This is why we get tan in the summer whether it

Applying a sunscreen with a skin protection factor of 15-30, wearing protective clothing such as thin jackets, hats, and sunglasses, and limiting time in the sun when possible are all effective options for protecting your skin against the effects of UV rays. I personally have an olive complexion and have never experienced the effects of sunburn and have often reveled in the tanning effect of time spent in the sun. It is now clear to me that no matter your skin tone, it is crucial to protect yourself from the deeper effects of exposure to UV rays and it is not as simple as using sunscreen to avoid a burn. Additionally, informing others of the significant risk associated with tanning beds is everyone’s responsibility. The risk of melanoma increases by 75% to those who use tanning beds before the age of 35; it is painfully clear that dangers of allowing the benefits of a temporarily dark complexion to outweigh the risks is both irresponsible and

Dermatologists, physicists, and scientists conducted a workshop of UVA treatment, and the workshop’s findings are presented in the New England Journal of Medicine. A previous president of the American Academy of Dermatology wrote an article titled “UVA1 is Often A1” to discuss their findings. The workshop found that medium or high-dose UVA1 works well with morphea, urticarial pigmentosa, atopic dermatitis, dyshydrotic dermatitis, subacute pruigo, and systemic lupus erythematosus. These diseases are treated by UVA rays because the wavelength is longer, which means there is less energy delivered to the skin and the greater penetration of photons (Dahl, 2012). Dermatologists even use sunbeds with higher intensity than regular tanning beds in their offices. For example, Windsor Dermatology uses four different types of light therapy to treat the skin condition psoriasis. One type of light therapy is that of UVA. The anti-inflammatory properties of ultraviolet light aid in slowing the growth of psoriasis effected skin

Great presentation! Before your presentation I did not know the difference  between UVA and UVB.  Also, another eye opener was the risk for developing melanoma increasing to 75% with tanning bed use before age 35.  Tanning is just another issue that our younger generations are encouraged to participate in without fully understanding the risk.  Your diagram of the ABCDEs for detecting melanoma was a great reminder of what we should be looking for.  I once had a dermatologist give me some very useful advise.  He stated when you see a mole, imagine a line going vertically  down the middle of the mole.  When you look at the two halves, compare them.  He stated the two halves should look like a mirror image of each other.  If in doubt, we should

“Indoor tanning under the age of 18 increases your risk of skin cancer by 75%”(Division of Cancer Prevention Ceanter). Over 10,000 people are expected to die this year from UV related causes. However, many people will disregard these facts and continue on with their harmful habits. There are many effects of artificial tanning and prolonged exposure to the sun. Many people have no idea about the risks of prolonged exposure to the sun, how dangerous artificial tanning actually is, or how radiation is not the only harmful trait of indoor tanning.

Before one can discuss harmful effects of tanning equipment and increased sun exposure, one must be familiar with the components of ultraviolet light and how affects the skin. Sunlight contains two types of ultraviolet (UV) light: UVA and UVB. UVA rays consist of longer wavelengths that penetrate deep into the dermal layer of skin. Limited exposure to UVA rays causes skin to tan; however, most experts agree that overexposure to UVA can lead to other long-term skin damage. UVB rays’ wavelengths are much shorter, affecting the outermost layers of skin. UVB rays are known as the "burning rays" and are considered more dangerous. Tanning beds and sun lamps generally emit 93% to 99% UVA

UV radiation, such as that from the sun can be very harmful. It has been shown to cause many different mutations within cells, leading to issues for the organism such as death or disease. One of the most prevalent sources of UV radiation for humans is the sun. It’s very important for us to know the extent of cellular damage that can be caused by this radiation, as to know how harmful the sun’s rays are to us as humans. One way that the damage caused by the suns radiation can be tested is through the model organism yeast. For this lab, we exposed two different strains of yeast to UV radiation to test its affects. One strain was able to self-repair, while one was genetically altered so that it could not. Observations were recorded at

Ultraviolet, or UV rays can damage skin cells which can lead to skin cancer. The SPF on sunscreen bottles stands for Sun Protection Factor, and refers to how well the sunscreen protects our skin against one type of UV radiation, called UVB. Some of the UV radiation from the sun still gets through the sunscreen and gets absorbed by our skin. Sunscreens are usually made up

Several findings are made based on the results: UV radiation can cause cell death by inducing genetic mutation, which agree with Diepegen et al. (2012)’s finding regarding UV radiation’s destructive effect at a cellular level. Photoprotective agents can effectively prevent and reduce UV radiation induced damage to cells. Similar findings were made by Quatrano and Dinulos (2013), who indicated that sunscreen contains active ingredient that absorbs UV radiation ranging between 290-400 nm. This experiment proves that photoprotective agents with higher SPF values are more effective in absorbing UV radiation. Indicated by Green et al. (2011), they suggested that regular application of high SPF sunscreen will prevent melanoma.

Individuals who get a considerable measure of presentation to bright (UV) beams are at more serious hazard for skin cancer. Sunlight is the fundamental wellspring of UV beams, yet you don't need to keep away from the sun totally. What's more, it is hasty to remain inside if it would shield you from being dynamic, in light of the fact that physical action is imperative for good wellbeing. Yet, getting excessively sun can be unsafe. There are a few stages you can take to confine your presentation to UV

Ultraviolet (UV) radiation is present in normal sunlight and sunlamps. “The sun emits energy over a broad spectrum of wavelengths: visible light that [one] can see, infrared radiation that [one] feels as heat, and ultraviolet (UV) radiation that [one] cannot see or feel. UV radiation has a shorter wavelength and higher energy than visible light. It affects human health both positively and negatively” (U.S. EPA). There are multiple types of ultraviolet radiation known to scientists and each affects human in different ways. “The longer ultraviolet rays (UVA), which penetrate deep into the skin, are responsible for tanning. Shorter rays (UVB) damage superficial skin cell layers, causing sunburn” (Harvard). Medical researchers at the Skin Cancer Foundation found that “the cumulative damage caused by UV radiation can lead to premature skin aging (wrinkles, lax skin, brown spots, and more), as well as skin cancer” (Skin Cancer Foundation).

The sun contributes to different health conditions, in its own way. Nonmelanoma and melanoma are both a result of the harmful ultraviolet radiation from the sun. Even though basking in the sun on a beach may seem fun and enjoyable, the excessive exposure to the sun can change the texture and look of the skin, resulting in skin damage. Cataracts, which are also caused by increased UV exposure, can cause an individual to lose their sight, if not treated. Increased heat can also cause dehydration. The immune system can be greatly affected by excessive sun exposure, affecting the body’s ability to fight infections.

A major function of melanin is to act as a defensive barrier of the skin against radiation damage. Ultraviolet light between the wavelengths 280-320nm (UV-B) causes sunburn and damages the skin on nonpigmented peoples. Exposure to this degree of light causes their skin to become dry, leathery, and wrinkled in appearance similar to that associated with aging. This can be seen in Whites living in Australia and South Africa, where ultraviolet light intensity is high because of the relative latitude or closeness to the equator.
