info on tanning

[southerntanr]

I need some tangeable, valid info that says that tanning is not fatal. not like skin cancer, but like actually going to the tanning can "cook" your insides. any websites will be greatly appreciated!

Tanning does not cook your insides, Total MYTH! Where do people come up with this Stuff? The original yarn-spinners confused microwaves with UV rays. UV rays don't cook your insides, but there's no doubt they do a little heating of your skin.

Here is a noted doctors speach. It may be of benefit to you. I personally along with others in our industry have answered negative statements from media and other sources. I have accumlated these throughout the years. Copies are available to you, if desired. My email address is rogerb@puretan.net. If I may help, do not hesitate to contact me.


To understand the tanning process, one first needs to realize that the skin is comprised of several types of cells. Each type of cell maintains a specific function. Realizing your skin is an organ, rather than something that may only survive light abuse, places the proper perspective on it. Your skin is a wonderfully resilient organ that for the most part can survive virtually any form of punishment. The skin is the body's boundary, tough enough to resist many environmental assaults, yet sensitive enough to feel a breeze or even sunlight.

As a versatile organ, skin creates the first line of defense against possible outside invasions by bacteria and germs. Also, the skin reacts to maintain the body's internal environment with small variations in degrees of normality, throughout our lifetimes. The skin also secretes fluids that lubricate it and barricade toxic substances, while maintaining this environment.

The skin is divided into two sections, the epidermis, being the outer layer and the dermis, or inner layer. The epidermis is divided into two separate layers, the horny layer (outer) and the germ layer (inner). At the base of the epidermis, cells denoted as melanocytes and they produce a substance called melanin (pigment). When UV light penetrates the epidermis to the melanocytes area of the skin, they become excited or activated and UVB light moves these cells into the upper region of the germ layer into the horny layer of the epidermis where a process like oxidation occurs: This process has an ingredient, tyrosine, an amino acid which reacts with the melanin. Thusly, the UVA oxidizes the skin and complete melanogenesis (the tanning process) occurs. This being denoted, every individual can produce their volume of melanin, which is determined by an individual’s traits and skin make-up. Although a person may gradually increase the amount of melanin production through tanning, the person cannot change from one skin type to another. Skin types are designated as #1 through #4 (see following chart).

One function of the skin is to protect its underlying tissues from invisible radiation such as that produced by the sun. The sun emits three kinds of ultraviolet rays, UV-A, UV-B, and UV-C. Although invisible, you can see the results of ultraviolet rays in such things as the growth of plants, warmth and tanning of human’s skin. UV-C is the shortest, most harmful wavelength of ultraviolet rays, but is virtually filtered by the earth’s ozone layer and pollution. UV-B is the medium wavelength and although overexposure can cause erythema (sunburn), a controlled amount is required to stimulate melanin that is necessary to initiate tanning of one’s skin. UV-A is the longest wavelength and is responsible for the completion or oxidation of the skins tanning process.

Tanning is the body's natural defense mechanism incorporated to protect itself from the sun’s rays. The outer surface or horny layer is the first shield against any invader. These cells develop from the living basal cells, which are constantly dividing and shedding, while activating new cellular growth (named for their location at the base of the epidermis). New cells are produced, expanding from the base by rapidly dividing basal cells. These new cells produce greater quantities of a protein cell called keratin. The fibrous keratin accumulates within the cells until it amorously replaces their living cellular structure. This journey to the surface takes approximately four to five weeks. At this time they have withered, become completely dormant and bound themselves firmly to one another. This forms a tough nearly impermeable shell to the epidermis. Perpetual shedding of this horny layer

prevents many microbes from penetrating the skin. As the epidermis goes about the business of renewing the horny layer, it sheds the dried out cells at an approximate rate of one million in every forty minutes. This horny layer will become thicker and tough, in response to UV to protect the skin from overexposure.

Ultraviolet B initiates the tanning process by stimulating the melanocytes, releasing melanin into surrounding cells. The degree of coloring achieved depends on the amount of melanin one has, the duration of the exposure and the individual's reaction to the ultraviolet rays.

The tanning process or increased pigmentation occurs in two phases. The first one is immediate pigment’ darkening (IPO). IPO is a rapid darkening of the skin, which begins during exposure to UV radiation, and its maximum effect is visible immediately. It is caused by a change in melanin already present in the skin. It occurs after exposure to the longer wavelengths of UVB, UVA or visible light. IPO may fade within minutes of small exposures or may last several days after longer exposures and blend in with delayed tanning.

Delayed tanning, induced by UVB exposure, is the result of increased epidermal melanin and first becomes visible 72 hours after exposure. Both UV A and UVB radiation start delayed tanning by creating an excited condition in the melanocytes, which in turn releases more melanin into the skin. The degree of IPD is primarily a reflection of the person's skin type. Delayed tanning demands longer doses of both UV A and UVB for any given response.







Skin
Type Sun Sensitivity Pigment Response Results


1 Very sensitive-Always burns easily Tans little or none, even with repeated
exposure


2 Very Sensitive, Always burns Tans w/difficulty after repeated exposures


3 Sensitive, Burns moderately Tans gradually w/light tones


4 Moderately Sensitive, burns minimal Tans easily w/moderate shade-tone


5 Minimally Sensitive, Rarely burns Tans exceptionally w/ darker tones


6 Insensitive, Never burns Extreme color w/deeply pigmented black

One constantly hears of reports, which describe the negative effects of the sun's rays on the human skin. Often such information is based upon the ignorance and misunderstanding of biological phenomena. The interspersed opinions originate mostly from partially biased skin doctors. They view the skin as an isolated organ, without consideration to the relationship to the total organism. The following discussion should therefore clarify the physiological foundation of light exposure and define both the “bright” and “dark” sides of the same.

Sun irradiation and, of course, artificial irradiation are electromagnetic waves and thus energy carriers. Skin damage (photodermatosis) occurs when the chemical substance of the nucleus (above all DNS) absorbs energy from the electromagnetic waves of UV light and produces a condition. A breakdown (photodimer) of individual chemical information carriers (base) can develop. In addition to this, the assumption is that the irradiation is of sufficiently strong energy packets (light quanta). The quantum energy of the UVA light is simply too weak to cause this electronic stimulation. A chemical reaction of the base and therefore an injury from the light is more than practically impossible.

On the level of higher energy, UVB light could more than likely cause damage, which is a reason why this radiation must be closely monitored. Inflammation due to light must be closely monitored.

Chronic light damage occurs after repeated acute DNA damage, the repair mechanism of the individual cells is exhausted and then these reproduce with altered hereditary information (mutation). If the body doesn't succeed in rejecting such mutants, senile skin (elastosis) or even skin cancer can result.

Special construction of irradiation units these days allows little possibility of damage from light, if the irritation time is correctly observed. These units produce mostly UVA radiation. The UVA radiation components can be ignored, as long as the skin types are not overly sensitive to light or even allergic to light. If, however, one tried to remove the sun energy from the organism, this would lead to severe damage. Deficient sunlight, according to the latest discovery, is the cause or trigger of diseases, which can be compensated by appropriate irradiation.

Thus various calcium-deficiency symptoms improve or are cured, because the vital calcium intake of Vitamin D3 is almost exclusively created through light.

Irradiation detectably raises the oxygen pressure in blood. Through UV light, the cell respiration is activated along with euros other body functions. A hemoglobin deficiency induced by light deficiency is regenerated by the effect, which results in an increased transportation of oxygen in the blood.

Through irradiation a weakened liver or gall function can be stimulated and the bilirubin level, which could lead to brain damage, can be reduced. Therefore, approximate1y 25% of all premature births in the U.S.A. are artificially irradiated, in order to prevent such injuries

One of the sad truths about our News Media is the implication that indoor tanning causes cancer and should be avoided at all costs. First of all UV light does not go any deeper than the depth of a floppy disk, for those of us who remember what they are. And those who don't, it is the depth of a piece of cardboard. And not only that but it doesn't act like for example microwaves. If you put a peice of pizza in the microwave and another exact piece in a tanning bed, set the timers to 20 minutes and just stand back and look what happens to them. I would just LOVE to see them report the WHOLE truth, not just bits and pieces and then leave the consumer to guess what happens next. I would strongly encourage anyone who isn't to sign up on line to become a Smart Tan member, and also to get Smart Tan certified. This will provide education that you can then use to educate your customers and not just be guessing about your facts. Not all of us graduated with a Science Degree. I sure didn't. But I am educated through the Smart Tan Network that also keeps up with each states regulations. Thank you for listening

UV rays! And that water!? That's why my grass is dying too!

[lioness]

I went to the Smart Tan site and it was really informative & I appreciate you posting it. I emailed it to alot of my friends that are not a believer that indoor tanning can be beneficial to your health as well as make you look wonderful! Thanks!
