In Madeira the state of the ozone layer is not significantly different from other regions around the same latitude belt, observing a negative trend of about 3% per decade during the last 30 years. The concerns about UV-B increase due to a global ozone layer depletion leads to an increase of the UV-B radiation which causes sunburns on skin, skin cancer, cataracts and other effects on human health. Recommendation measures for UV protection for highly sensitive skin:

  • UVI Extreme(greater than 9.0): Avoid as much as possible sun exposure. Rest at home.
  • UVI High(from 7.0 to 8.9): Use sun glasses with UV filters, hat, T-shirt, umbrella, sunscreen and avoid children's exposure to sun.
  • UVI Moderate(from 4.0 to 6.9): Use sun glasses with UV filters, hat, T-shirt , and sunscreen.
  • UVI Low(less than 4.0): Use sun glasses and sunscreen.
  • Avoid going outdoors between 11am to 3pm when the sun is highest.
  • Always choose shaded areas when outdoors.
  • Wear a hat which shades the face, ears and back of the neck.
  • Wear clothing that covers the arms, legs and the body.
  • Apply at least a SPF 15 sunscreen to all areas of the body that are not covered by clothing.
  • Apply sunscreen every two hours after swimming or activities causing heavy perspiration.
  • Children should be protected with shade, suitable clothing, hats, sunglasses and sunscreen.
