The skin cancer associated with sun exposure is each time more frequent, and the percentage of incidence has been increasing exponentially. That said, all the cares are few when we go out a lot of time in the sun.
It is certain and well known that you should avoid take a scald, but who has not got at least one or two scalds in life? Probably many of us. Now, will that really knows what are the consequences that one or two scalds can cause?
In fact, the scalds are something very dangerous, especially for children and adolescents because, at this stage of life, the scalds to increase in the immediate probability of that they may have skin cancer in adulthood. Speaking in numbers, and cases more specific, if you catch at least 5 scalds between 15 and 20 years of age, the risk of having melanoma (a type of skin cancer) increases by 80%. As for the other types of skin cancer the risk increases to about 68%.Although sunscreens protect against UV rays and against possible skin cancers that may arise due to exposure to the sun without protection, their use in the full year of 2015 is still neglected by a high percentage of the population.
IT IS NOT JUST THE SKIN THAT IS AT RISK
The majority of skin cancers are caused by exposure to the rays Ultra Violet, but there is also another part of the body that may be at risk: eyes.
A problem not so often (including to the Portuguese, as most of them have dark eyes) but still occurs, particularly increase risk of cancer in the eyes and the risk of developing cataracts. Thus, people with light eyes should not dismiss the sunglasses in very hot weather and Ultra Violet radiation.
THE RAYS ULTRA VIOLET
There are 3 types of uv:
- UVA are the type of radiation most common and are not absorbed by the ozone layer.
- UVB are mostly absorbed by the ozone layer, however some rays are still able to penetrate to the earth.
- UVC are very dangerous but you don’t need to worry since they are absorbed by the ozone layer.
As you know, the main source of uv is the sun, however, there are lamps and other systems, such as the use of tanning beds, that try to “mimic” the solar radiation. Use these methods to obtain a perfect tan is not only counter productive as it increases the risk of developing skin cancer.
WHY IS IT THAT THE UV RAYS ARE DANGEROUS?
UV rays are dangerous due to what is known as ionizing radiation. This type of rays can penetrate the skin and damage DNA and can cause cancer.
Does this mean that you should never can catch the sun? No, nothing like that! In fact, the sun is vital to our health and it is important to ensure a sun exposure daily (in the hours of less heat and radiation) for the proper production of vitamin D by our body. Do not be fooled by any information which may have been circulating in social networks about sunscreens not to be important sources of protection of the skin. The risk associated with the exposure to UV rays is real and protection is crucial.
