Everything You Need To Know About Sun Protection
Sun could be our best friend or our worst enemy. It is wonderful to enjoy sun but we should always remember to protect ourselves properly from Ultraviolet sun radiation that can cause many health problems.
Ultraviolet sun radiation (UV) is divided into three zones UVA, UVB and UVC. All of these zones have different – mostly negative – effects on the skin.
UVC Sun Rays
The UVC rays are the most dangerous. In biological laboratories they are being used for disinfection and extermination of bacteria. Luckily, these rays are blocked – so far at least – from the atmospheric ozone.
UVB Sun Rays
The rays that can actually reach us, the UVB are especially dangerous for the skin, because they directly affect the DNA of our cells, they are responsible for premature aging and the onset of skin cancer. They could also cause solar erythema, burns and sunstroke.They have the ability to induce melanogenesis, i.e. melanin synthesis by melanocytes and that makes them responsible for stains on the skin.
UVA Syn Rays
The effect of UVA rays for many years was relatively unknown. The scientific research in recent years has shown that they are equally dangerous to UVB. The presence of the UVA rays are constant throughout the daytime, while the UVB are at their maximum intensity at the time between 10 a.m. – 16:00
UVA rays are responsible for photoaging because a part of them reaches the dermis, the layer that lies under the skin and destroy collagen and elastin, the fibers that maintain the firmness and elasticity of the skin. Moreover, they weaken the immune system of the body causing cell damage, photo-sensitivity, allergic reactions and skin cancer.
Sunburns, Photo-damage and Sunspots
A single sunburn on a child’s skin automatically doubles the possibility of skin cancer when he grows up. The right sun protection up to the age of 12 years is crucial and reduces the risk of skin cancer by 80%.
We should not forget that tan is a visible proof of damage caused to our skin whenever it is exposed to the sun. The skin cells in order to defend themselves produce melanin while protecting the skin by increasing the rate of self-defense so the skin’s surface becomes more rough.In parallel, the degeneration of collagen and elastin deprives the skin of its “structural skeleton” that holds firm and elastic. The photo-damaged skin is characterized by the depth of the wrinkles and the yellowish color.
In the basal layer reduction of the number of melanocytes is observed – especially after our 30 years of age -. For this reason when we grow older tanning becomes more difficult. However, the density of melanosomes increases with age resulting in unevenly distributed melanin that causes freckles or sunspots to appear on the skin’s surface.
Sunscreen filters bind the UV rays and protect the skin from direct damage which is caused by the sun, like a burn. For many years, the protection provided was limited to UVB radiation. Today, the new generation of sunscreen products contain broad spectrum filters which can protect the skin by both UVB and UVA rays. It is essential to use a sunscreen that offers good protection from both UVB and UVA sun rays. We have recently posted an article containing the best sunscreens for 2015 that offer that kind of protection. Click here to read it.
The initials SPF, FPS and IP mean the same thing: the time we can stay in the sun without being burned. For example, if no sunscreen can stay 10 minutes in the sun, when you use a product with SPF 15, we can theoretically 15X our exposure time without danger. The SPF mainly refers to the degree of protection common to each product marketed.
Melanoma is called a malignant tumor of the skin which can occur from a nevus (olive) already existed, or from healthy skin. In recent years the number of melanomas has increased significantly. Each year in Europe and the United States one million tumors are diagnosed. Malignant melanoma is 1% of such cancer. Although melanoma when diagnosed early could be cured 100%, there is a high death rate from this type of cancer, especially in young people.
How to Prevent Skin Cancer
Warts documented through video is a safe method of preventing skin cancer. With the help of a video camera, the doctor makes an accurate record of all the moles using your body’s panoramic views. This provides the ability to trace each individual nevus.
Those nevi require close monitoring photographed one to one through digital technology with Dermatoscopes (skin microscope). The dermatoscope enables recording of some moles that are not visible otherwise. The image processing then special computer program analyzing it. In seconds we have a comprehensive risk assessment of the nevus.
That device significantly increases the percentage of accuracy of melanoma diagnosis. All images are stored electronically. This facilitates an accurate comparison with previous photographic later. Even the slightest change can be detected.
Even when patients have large numbers of moles on their bodies, none of them will go unnoticed thanks to the storage of skin illustration. That way, surgical removal of harmless moles could be avoided.
PRACTICAL TIPS TO REDUCE THE RISK OF EXPOSURE TO THE SUN.
- Gradual and brief exposure to the sun – not fast tanning
- Reduce exposure time to the sun
- Diet rich in B – carotene fruits and vegetables
- Preparing the skin
- Hat, umbrella, shade.
- Sunscreen, (renewable every 2 hours) even in winter … even in the shade or cloudy weather.
- Hydration and moisturizing products.
