l hole ozone layer. 
The Health and environmental authorities in Chile are beginning to delve into the spring and summer season around the recommendations of the precautions to be taken by increased solar radiation, so as to prevent sunburn, burns, and other diseases that more severe as skin cancer.
cities in northern Chile are the most sensitive and take into account that the hours between 10 the morning and four in the afternoon are particularly dangerous because of the volume of radiation.
hole ozone layer
" formed at the level where lies the ozone layer the Antarctic stratosphere is characterized by a decrease in ozone concentration due to release chlorine molecules from clouds formed during the winter at low temperatures. The release of chlorine is produced to dissipate these clouds with the arrival of the first sun after the night that covers the entire Antarctic winter.
Use wide-brimmed hats.
The Health and environmental authorities in Chile are beginning to delve into the spring and summer season around the recommendations of the precautions to be taken by increased solar radiation, so as to prevent sunburn, burns, and other diseases that more severe as skin cancer. in Chile is extremely dangerous sun exposure especially in the dates environmental warning alerts which are reported by the media throughout the country on news on progress, urging the use of hats, umbrellas, light clothing and cover exposed parts, and use of sunscreens.
¨ The authorities' emphasis relates largely to the alarming expansion of the hole in the ozone layer (which filters out ultraviolet rays), and in its measurement September recorded a size of 27 million square kilometers of Antarctica, similar in size to the U.S. territory.
From more than three decades ago, every spring in the southern hemisphere shows the phenomenon known as "
" formed at the level where lies the ozone layer the Antarctic stratosphere is characterized by a decrease in ozone concentration due to release chlorine molecules from clouds formed during the winter at low temperatures. The release of chlorine is produced to dissipate these clouds with the arrival of the first sun after the night that covers the entire Antarctic winter.
Typically, the hole in the ozone layer starts to form in early August, reaching its peak in the second half of September, while from the end of this month, begins to decrease slowly and disappear by mid-December. ¨

Skin Cancer in Chile
On the other side of the world, in Chile, both the rates of incidence and the mortality from this cancer has increased dramatically. This is demonstrated by a study of the Hospital of the University of Chile, whose results show a 158% increase in the incidence of malignant melanoma in six years (from 1992 to 1998) in the metropolitan region. This means that the inhabitants of the capital are nearly three times more likely to get that in the past.
initial diagnosis
This cancer begins with a small mole that changes color and form, with little signs of redness around and, sometimes, pain. The doctor will look at the size, shape, color and texture of the area in question, and if it bleed or peel. Further consideration by the rest of the body to see if you have spots or moles that may be related.
Prevent
The population most affected by this cancer are those with skin type I (white skin, eyes and blond hair, tan little sun exposure), patients with intense sun exposure for your type of work (farmers, etc.) or training (sailing, etc.), and geographical location (tropical or with significant levels of UV rays.) Babies under six months should not be exposed to sunlight and children should be extremely careful with your skin and that between 50% and 75% of the amount of UV received by a person are captured before 18.
men compared with women are twice as likely to develop basal cell cancer and three times more to develop squamous cell cancer
Remember these tips:
Use wide-brimmed hats.
- Use sunscreens with physical and chemical screen, which will appear 20 minutes before sun exposure or the bathroom and reapplied every 2 to 6 hours but says it is against the water.
- Use sunglasses.
- Avoid the sun between 10:00 am and 4:00 pm.
- Playing in the shade.
- Do not use tanning booths. Exposure of skin to excessive ultraviolet light can increase the risk of developing
