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.
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.
