The Difference Between Uv And Uv Essay

Many people think that is it possible to achieve a “healthy tan,” but this thought has been proven wrong. Overexpose to UV-A and UV-B rays from the sun lead to premature aging of the skin, as well as the possible formation of skin cancer, know as melanoma. An appearance of a tan is actually a stage of burning and damage to the skin. Although a tan may be desirable to many, the fact remains that more people need to be educated on the dangers of the sun’s harmful rays, and the possible health complications of overexposure.

The other cause is the degree of pigmentation of the skin. Individuals with the highest risk are people who live in sunny places and people who have fair skin. The areas of the body that are the most exposed to sunlight are the areas of the face and head. Here, cancer is more likely to develop. (Bair, 1991, P. 368).

These brown coloured cancerous growths develop when unrepaired DNA has committed damage to the body’s skin cells. It is known that it is the most commonly triggered by vigorous amounts of sunshine, over excessive use of tanning bed and UV lights which result in making mutations in the skin that produces the skin cells to over multiply at a quick rate which can eventually form nasty tumours.

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,

As many as ninety percent of melanomas are estimated to be caused ultra violet (UV) exposure. This includes UV exposure from artificial sources, such as tanning beds. “Strong evidence now links tanning beds to melanoma, a deadly form of skin cancer that afflicts nearly 69,000 Americans a year.”—USA Today. The more one tans and the younger one is your risk for melanoma increases. However, melanoma is increasing faster in women 15-29 years old, than in men the same age. Furthermore, 10,000 people die from melanoma. This is mainly caused because of tanning beds. As a matter of fact, a person dies every fifty minutes from melanoma, the second most common cancer. Tanning beds triple the risk of one getting melanoma. In fact, every time one goes and tans, the risk gets higher and higher. Following this further, more people get melanoma because of tanning beds than developing lung cancer because of

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

United States. Skin cancer has been the most popular form of cancer that is growing especially since the invention of tanning beds. Sun exposure and radiation exposure increase the risk of skin cancer. The definition of cancer is abnormal cell growth or behavior. Studies have shown that sun and radiation exposure damage the cells in your body. Richard Wagman is the author of this article; he is a doctor who specializes in internal medicine.

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

UVB stands for Ultraviolet B. These rays penetrate the upper layers of the skin known as the epidermis and cause the skin to burn. UVA stands for Ultraviolet A. These rays penetrate deeper through the epidermis into the lower layers of skin known as the dermis.

C. Melanoma Skin Cancer is the most dangerous form of skin cancer, it kills one person per hour, these cancerous growths are most often caused by ultraviolet radiation from sunshine or tanning beds. These tumors originate in the pigment-producing melanocytes in the basal layer of the epidermis. Melanoma is caused mainly by intense, occasional UV exposure (frequently leading to sunburn), especially in those who are genetically predisposed to the disease. Often the first sign of melanoma is a change in the size, shape, color or feel of a mole.

Cancer is the second biggest killer in the United States. Anyone can develop cancer, and the older we are, the more likely we are to develop the disease. Out of all the different kinds of cancers skin cancer is the most common human cancer. Approximately 40 to 50 percent of 65 year olds in the United States will develop at least one form of skin cancer. People who live closer to the beach are at a high risk of developing skin cancer due to the higher ultraviolet radiation levels at this location.

There are many internal health concerns that are also caused by tanning. Ultraviolet-A and ultraviolet-B radiation not only damage the outer systems, but they also damage the inside of the body systems. Ultraviolet-A rays affect the lower sections of the skin. These rays are the ones found in regular tanning beds, ultraviolet-B

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.

Every hour at least one American will die of skin cancer caused by exposure to the sun. These statistics are alarming and most people are unaware that the sunshine that we all love so much is in fact a threat to our health and good looks. It is up to us to educate ourselves and our children on the harmful effects of sun exposure on the human body like premature aging, physical damage to the body, and cancerous diseases.
