How to Protect Skin
Skin is probably one of the the bulk important parts of your body for it protects you from a host of diseases that may pose a threat to your existence. It is our body’s major line of defense. It guards you from all infections and insulates your body from the ever-fluctuating external environment in order to keep a relatively stable body temperature. It is the body’s major point of contact to the outside world, sending constant information to the brain about pain, heat, texture, cold, etc. With this in mind, there is no doubt that proper skin care and staying away from skin detrimental activities will do yourself and your skin particularly, a almighty favor. Skin Cancer Like the bulk part of our body, the skin is also likely to develop cancer. Cancer is a result of an uncontrolled cell growth in one part of the body. Unlike common cells which are programmed to divide, grow, and die at a certain time, cancer cells lack the internal machinery to control growth and as a result cause severe undermine to common cells that would be outnumbered along the way in a certain biological locality. Technically, the body reacts in a lot ways to cancer cells but this abnormality causes other diseases to suffer nutritional death. Cancer cells were found to cause the body to produce numerous blood vessel connections along the cancerous portion thereby depriving common cells with nutrients. Some cells even detach from their point of origin and travel to other parts of the body to beginning a new colony of cancer cells. Skin cancers are either melanoma or non-melanoma cancers. Non-melanomas are cancers which arise from skin cells other than melanocytes cells. Melanomas are cancerous melanocytes cells that produce melanin, a pigment that gives the skin its characteristic color. UV Rays The sun is one of the key enemies of the skin. Although sunlight helps the skin synthesize vitamin D (cholecalciferol), excessive and prolonged exposure to the sun causes undermine and wrinkling. How does the sun cause such damage? Sunlight that passes via earth is composed of visible light and ultraviolet light (UV). UVA and UVB Light are one of the the bulk common ultraviolet lights. UV lights falls outside the visible light spectrum, meaning, the human eye cannot observe this type of light and can only be seen using a sophisticated tool which detects dissimilar light wavelength across the light spectrum. The difference between the two UV light lies in their capability to undermine skin cells. UVB light doesn’t get via the deeper layer of the skin and accounts for visible burns and DNA undermine across the top layer of the skin. UVA light, on the other hand, penetrates via the deeper layer of the skin and activates free radicals (very reactive substances), which cause minute damages to the skin. Cumulative undermine accounts for the skin’s premature aging. SPFs, Lifestyle and Diet There are misconceptions about skin color. People believe that the fairer you are, the more you're likely to suffer burns caused by exposure to sunlight. That may be partly true, but overexposure to UV light can cause grave skin problems. If you go outdoors and cannot avoid exposing yourself to the injurious sunrays, the following recommendations will surely save you from the aftermath of excessive sun exposure: · Wear protective sunscreen – More and more people are starting to realize the importance of wearing lotions with Sun Protection Factor ingredients (SPF). SPFs sunscreen lotions are effective in blocking UV lights from penetrating via your skin. Intensive application should be made on laid bare spots of the body such as the lower arm and legs, ear lobes, nose, feet and the face. Choose sunscreens that contain a high amount of titanium dioxide, zinc oxide, benzophenone, oxybenzone, sulisobenzone and/or butyl methoxydibenzoylmethane known as avobenzone (Parsol 1979). · Wear Protective Fabric - Tightly woven clothing are effective in warding off undesirable UV rays. Today, some fabrics are labeled as how effective they are in intercepting UV rays. Hats with wide brim also consult a amazing amount of protection. · Minimize Unnecessary Exposure and Tanning – Unavoidable sun exposure such as recreation or as part of occupation is one of the hazards of every day life and enhances your risk of developing skin cancer later in life. If these cannot be avoided, make certainly to wear protective clothing and wear sunscreens apposite for a certain activity and your level of exposure. Increasing SPFs means increasing protection. Cosmetic tanning also poses the same kind of risk due to UV-induced damage. It uses UVA rays and does not cause obvious burns. The amount of undermine is comparable to UVB rays which cause visible tanning and damage. · Eat Right – Maintaining a well-balanced diet is critical to the maintenance of a healthy skin. Your grandma may have said it once to you but fruits and vegetables contain great skin rejuvenating ingredients. Fruits and Vegetables contain anti-oxidants such as vitamins C, D and E. These organic foodstuffs bind with highly reactive free radicals and neutralize them. They insulate the body against unwanted undermine caused by these extremely harmful chemicals. Whole grains, seeds, nuts, fish such as tuna and salmons are great sources of fatty acids and vital oils and keeps the skin hydrated. Fatty acids acts like a bullet vest in preventing UV rays from penetrating deeply into the skin causing too much damage. · Fluids such as water and juices also keep your skin dehydrated and minimize the effect of sun exposure. Research displays that dehydrated skin are more susceptible from burns and structural damage. Protecting the Skin from the Sun Yes, enjoying a sunny day on the beach is fun. However, when going out without proper skin protection one is risking himself of having skin diseases, one of which is the dreaded skin cancer. So to maintain the healthy, youthful glow of one's skin, it's indispensable to comprehend how the bad effects of the sun's ultraviolet or UV rays come into action. The UV-A and UV-B rays enter clouds, thick layers of glass, a meter of water, and the layers of the skin. UV-B makes the skin's top layers to release chemicals that permit the blood vessels' expansion and cause some fluid to leak, resulting to inflammation, pain and redness known as sunburn. This undermine can eventuate within an approximate of only 15 minutes and can continue to worsen for up to 72 hours after sun exposure. The damaged skin cells in the way will die and "molt off" in sheets or pictures. Peeling is the way in which the body disposes of dead skin cells. UV-A are the rays that obtain into the deeper layers of the skin. This affects the living skin cells under the surface of the skin. These rays not only bring about long-term undermine such as sagging, wrinkles and discoloration, they also give technique for the early stages of skin cancer. Here's some "geek speak" that's worth some brow-burning. The UV rays act like chain saws, shredding deep into the DNA (the genetic material, with a very precise structure, clear cut order and clear cut coding) found within the cell nuclei. Repair enzymes within the cell act by countering the undermine done on the DNA chain in shortest period possible. This undermine and repair happens simultaneously and constantly with the tempo of the repair keeping up with the extent of undermine being inflicted. But just like any other mechanism within the body, these repair enzymes have their limits and reaches the point that they can no longer work. When the undermine is too much (which springs up even before the skin turns red), the enzymes cannot cope. The result is a dismantled DNA structure which alters the coding and leads to the abnormality of skin cells or what is termed as mutation. This is the first step of the formation of cancer cells. UV-rays also add to the formation of superoxides which are extremely toxic chemicals the speeds up skin cell ageing. So who exactly are those in the threat of having skin cancer? People who have already experienced three or more bad cases of sunburn before reaching the age of twenty and regular sunbathers who always crave for an instant tan have greater dangers of picking up the dreaded skin disease known as melanoma. Cricketers, farmers, golf players and others, who have long exposure to the sun, have more tendencies to have milder forms of skin cancer. So after learning how the body reacts to sunlight here is some information on how to prevent its injurious effect. Ironically, studies on skin care express that Vitamin D, with the aid of sunlight exposure, is what can aid the body combat skin cancer. So how does one go out in the open without the paranoia of cancer haunting him? Dermatologists suggest the use of sunscreens. Researches showed that exposure to sunlight sans sunscreen should be less than 10 to 15 minutes at noon, while the sun is at its strongest. Using a sunscreen with an SPF or sun protection of 15 or higher is recommended. People with sensitive skin and the older adults should use an SPF of 30 or sturdier because their skin tends to burn more easily. People with allergies or sensitive skin should also take note of the ingredients and select those that are free of chemicals, dyes, preservatives, and alcohol. If sun exposure would be particularly high, using a sturdier sunscreen like zinc or titanium oxide is the better option, as it will completely stop sunlight from reaching the skin. Sunscreen application should be about half an hour before getting laid bare into the sun and reapplication should be done every few hours. And when going swimming, one should know that 98 percent of the sun's rays can pass via water, so without some kind of "water-resistant" sun screen and frequent applications, sunburn might be inevitable. The skin is meant to protect and shield one from the threats of the environment so unless one properly cares for it, it won't do its job that well. |
