Sun Exposure Uv Rays The Basic Facts
The human body benefits from sun exposure. And a little bit of tan protects you from the sun. Right? Wrong!
The body does indeed benefit from sun exposure. But a little bit of tan does not necessarily protect you from the sun. Let's see why.
The sun's rays are a major source of vitamin D and help the body's systems acquire much needed calcium for building healthy bones. However, most people don't need to spend large amounts of time exposed to the sun in order to get their required amount of vitamin D.
In fact, the body's health can actually suffer negative effects when it's exposed too long to the sun's rays, especially if it's unprotected. Results can vary from skin and eye damage to immune system suppression and ultimately cancer, even for the young.
So let's look at the basic facts about sun exposure.
There are three kinds of invisible ultraviolet (UV) rays in the sun that reaches earth: UVA, UVB, and UVC. When these rays come in contact with our skin, affects of UVA and UVB can be - tans, burns and other reactions (e.g. like acne and cancer).
It's also notable that the effects of all UV rays are not the same. Depending upon the season, time of day and place on the planet in relation to the sun - (i.e. your altitude and latitude), the rays' intensities vary. For example, during summertime, UV rays are at their strongest. Between 10 a.m. and 4 p.m., the rays are strongest. And close to the equator and at high altitudes (where air and cloud cover are less, resulting in increased harmful penetration of UV rays into the environment), the rays are also strongest.
In order to protect ourselves from the harmful UV rays, let's look at the skin's first defense - melanin.
Melanin is a chemical present in a variety of colors and concentrations in most people's skin that helps with defense from the sun. Melanin reacts with UV rays and absorbs them. Or rather, to be more specific, the rays act upon melanin, causing the melanin to spread out or grow, increasing its presence in response to the sun's exposure. The result? A 'sun tan'. The darker the skin color, the more melanin the skin has for protection. And 'tanning' for darker color is included here; 'color' does not have to refer to just the original skin color.
A word of caution...
Tanning may look great on the surface, - but the amount and length of time a person is exposed to the sun, determines the amount of possible damage. It also determines the future risk of damage that's likely.
For example, people who are exposed to the sun in huge doses like ship crews, field workers and beach surfers, are at higher risks for skin damage than indoor workers. What happens is that when the amount of UV exposure is greater than what the skin's melanin can handle, sunburn can result. And those with lighter, fairer skin, who have less melanin, absorb less UV, suffering less protection.
Since research has shown that UV damage from the sun is the main cause of skin cancer, (with as high as 20% of some populations developing skin cancer during their lifetime), we need to take a proactive approach in relation to sun exposure to avoid harmful skin damage.
As we say colloquially here in Australia - "Slip, Slop, Slap". (I.e. 'Slip' on a shirt, 'Slop' on a hat, 'Slap' on a sunscreen). Look after the skin you've got, because you're the one who will be living with it!
Cure Skin Cancer Natural Treatment

Did you know the majority of your sun exposure occurs before the age of 18, but can take years to surface as skin cancer? Get the information you need to participate in your care and recovery.
Beauty is only skin deep. But skin cancer goes much deeper. Teens quest for beauty not worth the cancer risk.
We think that this occurs only to the people of the mother's age but it occurs to the teenagers also. Skin cancer can be cured at its initial stage with the treatment and the precautions that are to be followed when suggested by the physician. But it goes deeper if it is abandoned for some period after its appearance. So we should be careful enough and take care of our skin.
Skin Cancer occurs mainly in people with fair skin, light eyes, and those who tend to freckle or burn easily during and after exposure to the sunlight. A history of 3 or more
sunburns, particularly blistering sunburns (before age 20) greatly increases risk. A history of severe sunburns in childhood and adolescence may actually double the risk of melanoma in adulthood.
Ultraviolet (UV) radiation from the sun is the main cause of skin cancer. Energy from the sun actually is a form of radiation. It consists of visible light and other rays that people can't see. Invisible infrared radiation, for instance, makes sunlight feel hot. UV also is invisible, and causes sunburn and sun tan. UV rays damage DNA, the genetic material that makes up genes. Genes control the growth and overall health of skin cells. If the genetic damage is severe, a normal skin cell may begin to grow in the uncontrolled, disorderly way of cancer cells. UV also can cause sunburn, and other damage that makes the skin look prematurely old and wrinkled.
Two kinds of rays exist in ultraviolet radiation invisible rays in sunlight that cause suntan, sunburn, premature skin aging, and most cases of skin cancer.:
* Ultraviolet A (UVA)
* Ultraviolet B (UVB)
Some cases of skin cancer, however, may be hereditary and run in families. In those cases, skin cancer is caused by abnormal genes that children inherit from their parents.
Genes make parents and children look somewhat alike. They also make them likely to get some of the same diseases.
Anyone can get skin cancer. Although most cases occur in people over age 50 with fair skin, it can develop in younger people, and those with dark skin. In general, an individual's lifetime exposure to UV light determines his risk. Certain individuals have a risk that is higher than the rest of the population. Included are people who:
Anti Aging Skin Care Products Myths
Anti aging skin care products
Are you looking for anti aging skin care products? Have you thought of buying one?
Anti aging skin care products remind me of the song '18 till I die'. Indeed, anti aging skin care products are very popular today; and why not, who doesn't want to look young for ever?
Talking of anti aging skin care products, the first thing that comes to mind is vitamin C based anti aging skin care products. These products work by enabling the synthesis of collagen (a structural protein that is found in skin). This category of anti aging skin care products is related to anti-oxidants. Anti aging skin care products that are based on vitamin C are, however, posed with the danger of getting oxidised themselves (as they come into contact with air during their usage). So some anti aging skin care products are based on the derivatives of vitamin C, which are more stable and less expensive. However, the effectiveness of such anti aging skin care is not as much as it is for vitamin C based ant aging skin care products.
Besides vitamin C, vitamin E and lipoic acid are anti-oxidants too. Vitamin E is a fat-soluble anti-oxidant that is found in human blood and helps in building resistance against infection. Vitamin E is also known to inhibit cancer. Liponic acid is known to combat the signs of aging very effectively by reversing the skin damage caused by the aging process.
Phytochemicals form the other category of anti aging skin care products. Phytochemical are special chemicals that are extracted from plants. There are a variety of phytochemicals that are in use today. Phytochemicals prevent occurrence of cancer of certain types; these include prostate cancer, breast cancer and colon cancer. That is why they find their place in anti aging skin care products.
Some B-vitamins like B5, B6 and B12 are also in use for anti aging skin care products.
The field of anti aging skin care products is vast and needs a lot of research. Though the currently available products are effective, they still have challenges to combat. Hopefully, these challenges will get resolved in due course and help get better and cheaper anti aging skin care products.
However, anti aging skin care products should be used only as a supplement to the natural ways of skin and body care. So, drinking a lot of water, getting a good night sleep, exercising regularly, maintaining healthy eating habits and keeping stress at bay are essential means of delaying the aging process. No anti aging skin care product can replace them really.
Now that you know everything about skin care products, it would be easier to choose which one is the best for you.
The Lifesaving Road Trip Screening Tour Raises Awareness About Skin Cancer
The statistics are staggering-and growing. More than 1.5 million people will be diagnosed with skin cancer this year. There are more new cases of skin cancer in the U.S. than breast, prostate, lung and colon cancer combined. The key to keeping skin healthy? Detect and treat skin cancer as early as possible. Caught in the early stages, skin cancer is treatable.
"Many people are at risk, but skin cancer is also one of the most preventable and treatable forms of cancer," says Dr. Mark Lebwohl, Professor and Chairman, Department of Dermatology, Mount Sinai School of Medicine, New York.
To raise awareness of skin cancer and early detection and treatment, The Skin Cancer Foundation and Doak Dermatologics, a division of Bradley Pharmaceuticals, Inc., have joined forces on an innovative public service campaign. Throughout 2006, The Skin Cancer Screening Tour is heading to major cities across the U.S. to perform this important service.
Doak Dermatologics has built a custom-designed Mobile Diagnosis Vehicle (MDv) that will be staffed by local, board-certified dermatologists in each city, ready to offer free skin cancer screenings. The physicians will be looking for four primary forms of skin cancer or precancerous skin conditions:
1. Actinic Keratosis (AK), which affects 1.3 million people annually. AK is the most common type of precancerous skin lesion. If left untreated, AK can lead to squamous cell carcinoma.
2. Squamous Cell Carcinoma (SCC) is a form of skin cancer that affects 200,000 Americans each year. SCC can metastasize (spread) quickly. SCCs that metastasize most often arise on mucous membranes or lips.
3. Basal Cell Carcinoma (BCC) is a common form of skin cancer, affecting more than 800,000 Americans annually. Chronic exposure to sunlight is most often the cause of BCC, which occurs most frequently on exposed parts of the body.
4. Melanoma is the most serious form of skin cancer and has increased more rapidly than any other form of skin cancer during the past 10 years. By 2010, melanoma is projected to rise in one in 50 Americans. If diagnosed and removed early, melanoma is almost 100% curable.
Get Screened Today!
When The Skin Cancer Screening Tour comes to town, be sure to pay it a visit. Of course, you don't have to wait for the MDv to get screened. Make an appointment with your local dermatologist for a screening as soon as you can.
Whether it's on the MDv or with your dermatologist, the important thing is to get screened early and, if required, treated. It could save your life.
A cross-country tour is helping drive many people toward better health.
Avoid Skin Cancer While You Enjoy The Outdoors
Here's a bright idea: There's a beautiful way you can protect yourself from an increased risk of skin cancer.
Through the work of nonprofit organizations, such as The Skin Cancer Foundation, the connection between sun exposure and elevated risks of skin cancer has become clearly established.
"Twenty-five years ago, few people knew about the dangers of excessive, cumulative sun exposure," says Perry Robins, M.D., president and founder of The Skin Cancer Foundation. "While the connection between sun exposure and skin cancer is widely known today, statistics show that the incidence of skin cancer is continuing to increase rapidly. More than 90 percent of skin cancers are caused by the sun. Nationally, there are more new cases of skin cancer each year than the combined incidence of breast, prostate, lung and colon cancer."
To help combat this growing health risk, The Skin Cancer Foundation conducts extensive educational programs and regularly reviews products that can help consumers reduce their health risks from sun exposure. More than 300 products in the U.S. and more than 70 products overseas have been awarded the Foundation's Seal of Recommendation.
Myths About Skin Cancer Are You Safe
Sara spends much of her summer near the beach. She lives in a mild climate and is very athletic. She loves to swim, bike, and play games outdoors. Sara knows the dangers of the sun and so she opts for tanning salons to get her 'golden glow' while being sure to apply sunscreen every day before heading out.
Joseph lives in a cooler, northern climate. The summers can be very humid, but most of the year is mild or even below freezing during the harshest winter months. The beach has never been much of a draw for him and he spends most of his time doing indoor activities or at his job. Joseph doesn't worry about sunscreen and only had one sunburn that he can remember and that was when he was a child.
Which of these examples do you most associate yourself with? Did you know that Sara and Joseph are both at risk of developing skin cancer? We have all heard the warnings about the dangers of sun exposure. We know all about the importance of wearing sunscreen and hats. But are YOU protected from skin cancer? Consider these myths and facts:
- Myth: Tanning Beds are Safer than the Sun
20 minutes of exposure in a tanning bed is roughly equivalent to four hours in the sun. Although sun beds use UVA rather than UVB rays, 'The Skin Cancer Answer' states that "UVA penetrates more deeply into the skin than UVB, can cause skin cancer, and may suppress the immune system."
- Myth: Wearing Sunscreen at the Beach is Protection
85 percent of UV rays can even make it through on cloudy days. That means you are equally at risk in the car, walking the dog or letting your children out to play at any time of year - even when you're not at the beach. Of course, you are usually less attired at the beach and so covering up is recommended even when wearing sunscreen. Sunscreen also wears off with sweat and water and should always be applied every two hours or after getting wet.
- Myth: Taking Care Of Your Skin Now Will Protect You
Sadly, skin cancer can take 20 or more years to develop. The Skin Cancer Foundation states that most people receive about 80 percent of their lifetime sun exposure before the age of 18. Just one blistering sunburn in childhood is estimated to double the risk of melanoma later in life. Taking better care now will reduce the risk, but not eliminate the damage already done.
- Myth: Having a Tan Means You're More Protected
Dark skinned individuals are less likely to develop cancer, but tanned skin is actually damaged skin. Repeated tanning injures the skin and increases the risk of skin cancer.
So how do you plan to protect your family this year? Some suggestions are to limit exposure to the sun - especially for infants. Examine your skin for early signs of damage. Use a sunscreen of SPF 15 or higher and apply it at least 30 minutes before exposure and every two hours after that. Teach your children good safety habits and be sure you and they are covered up when outdoors.
Have fun and be safe.
Diagnosing Skin Cancer
There are several different types of cancer, all of which are very dangerous and must be detected early in order to have the best possible prognosis. Skin cancer, which is an increasingly common form, is often associated with over exposure to sun or other ultraviolet radiation, including tanning beds. Because individuals with fair skin are more susceptible to a sunburn, they are also more susceptible to skin cancer. In order to protect themselves from the sun's strength, individuals should wear sunscreen with a high SPF, hats and long sleeve shirts. In addition, taking special care to not fall asleep in the sun or spend hours every day in it's presence may help to lessen it's harmful effects and possibly may even prevent skin cancer.
Symptoms of skin cancer are various, but the most common is a lesion that will not heal. This may also include discoloration and overall changes in the appearance of moles. The majority of skin cancer patients can be treated with a surgical procedure that involves removing the affected layers of the skin. If skin cancer is left untreated, however, it may begin to involve the deeper layers of the skin and possibly even the lymphatic system. In addition, it may spread to other parts of the body and become resistant to treatment if not detected early.
Of all the various forms of cancer, Skin cancer has one of the highest survival rates because, unlike the others, skin cancer is usually visible and leads to earlier detection. If a skin lesion does not heal within 7 to 10 days, or if a mole begins to change in shape, color or otherwise vary in appearance, a physician should be consulted in order to determine whether or not the lesion is cancerous. During testing, a piece of the skin will be removed by the physician and sent to a medical laboratory for further testing. If the test results are positive for the presence of cancer, the physician will invite the patient to return to his/her office for a conversation regarding possible treatment options.
The information in this article is intended for informational purposes only. It should not be considered as, or used in place of, medical advice or professional recommendations for the cause, diagnosis or treatment of skin cancer. If necessary, individuals should consult a medical doctor or dermatologist for information regarding the likelihood of skin cancer, a proper diagnosis and recommended form of treatment.
Sunburn Uv Overexposure Skin Cancer Prevention Or Cure
Overexposure to the sun and UV rays is rarely obvious at the time, - and on many occasions, probably quite unintentional. However repeated exposure has rather more adverse long-term implications for our bodies and our health.
We're all well aware of the more obvious and painful symptoms of sunburn including hot, red, tender skin - which in the case of a more heavy burn can also include blistering, peeling and dehydration.
The damage that occurs beneath the skin as a result of sunburn is considerably 'less obvious' at the time of exposure, and may in fact take years to produce symptoms visible to the naked eye.
The fact that damage caused to skin cells during sunburn can not only accelerate the aging process, but also increase the risk of cataracts and skin cancer, should certainly demand our attention.
When faced with the potential risk of having to treat more than just the temporary symptoms and pain of sunburn, doesn't it make more sense to avoid the risk in the first place?
Seek prevention rather than cure!
So before you venture out into the sun again, remember these important tips to protect yourself from overexposure of UV rays and sunburn, and its associated risks:
1. Wear protective clothing, including a long-sleeve shirt and a hat. Consider the 'additional' protection of an umbrella or shade where appropriate.
2. Avoid sun exposure between 10 am and 3 pm if at all possible.
3. Remember that UV rays are present even on cloudy days.
4. Remember that sunlight is strongly reflected from sand, snow, ice, water and concrete, which can intensify your direct sunlight exposure.
5. Apply sunscreen containing a sun protection factor (SPF) of at least 15, at least 15 minutes before going out into the sun.
6. Reapply sunscreen at regular intervals while out in the sun, especially if you are perspiring heavily or swimming.
7. Remember that UV overexposure is not limited to 'sun exposure'. Sunburn can also occur as a result of UV exposure from other sources including tanning beds/lamps, welding arcs etc.
Prevention is a far better treatment than cure. In the event however, that you discover any unusual moles or growths on your skin - (particularly if they're irregular in shape, bleed, itch, or appear to be changing) - consult your healthcare provider as soon as possible.
When it comes to overexposure of UV rays and sunburn that result in skin cancer, early detection will certainly assist in providing you with more effective treatment. But considering your options beforehand - what will provide the best outcome for your health? Prevention or Cure? I know which one I'd choose...!
