Simple Precautions In The Sun

  1. The UV index is a measure of the harmful Ultraviolet sunlight. It is not a measure of the “visible” sunlight or for the warmth of the Sun.
  2. The values given in our forecast are the highest UV index, that is the value around 1 p.m.
  3. The UV index values are valid for clear sky and broken cloud conditions.

    UV levels are highest under cloudless skies, and cloud cover generally reduces a person’s exposure. However, light or thin clouds have little effect and may even enhance UV levels because of scattering. Don’t be fooled by an overcast day or a cool breeze! Even a long stay in open shade, for example between buildings, may give a sensitive person a sunburn on a day with high UV levels.

  4. Be careful not to underestimate the amount of UV radiation passing through clouds

The rise in the incidence of skin cancers over the past decades is strongly related to increasingly popular outdoor activities and recreational exposure. Overexposure to sunlight is widely accepted as the underlying cause for harmful effects on the skin, eye and immune system. Experts believe that four out of five cases of skin cancer could be prevented, as UV damage is mostly avoidable.

Adopting the following simple precautions, can make all the difference. Shade, clothing and hats provide the best protection , applying sunscreen becomes necessary on those parts of the body that remain exposed like the face and hands. Sunscreen should never be used to prolong the duration of sun exposure.

Limit time in the midday sun
The sun’s UV rays are the strongest between 11 a.m. and 3 p.m. To the extent possible, limit exposure to the sun during these hours. PROTECT BABIES AND YOUNG CHILDREN: THIS IS PARTICULARLY IMPORTANT

Watch for the UV index
This important resource helps you plan your outdoor activities in ways that prevent overexposure to the sun’s rays. While you should always take precautions against overexposure, take special care to adopt sun safety practices when the UV Index predicts exposure levels of 3 or above.

The UV Index can:

  • Save your life
  • Protect good health
  • Help preserve youthful complexion

Use shade wisely
Seek shade when UV rays are the most intense, but keep in mind that shade structures such as trees, umbrellas or canopies do not offer complete sun protection.

Wear protective clothing
A hat with a wide brim offers good sun protection for your eyes, ears, face, and the back or your neck. Sunglasses that provide 99 to 100 percent UV-A and UV-B protection will greatly reduce eye damage from sun exposure. Tightly woven, loose fitting clothes will provide additional protection from the sun.

Use sunscreen

  • Apply a broad-spectrum sunscreen of SPF 20+ liberally and re-apply every two hours, or after working, swimming, playing or exercising outdoors.
  • Small amounts of UV are beneficial for people and essential in the production of vitamin D.
  • UV radiation is also used to treat several diseases, including rickets, psoriasis, eczema and jaundice. This takes place under medical supervision and the benefits of treatment tend to outweigh the risks of UV radiation exposure.
  • Overexposure to solar radiation may result in acute and chronic health effects on the skin, eye and immune system.
  • Children are in a dynamic state of growth, and are therefore more susceptible to environmental threats than adults. Many vital functions such as the immune system are not fully developed at birth, and unsafe environments may interfere with their normal development.
  • Many believe that only fair-skinned people need to be concerned about overexposure to the sun.
  • Darker skin has more protective melanin pigment, and the incidence of skin cancer is lower in dark-skinned people. Nevertheless skin cancers do occur with this group and unfortunately they are often detected at a later, more dangerous stage.
  • The risk of UV-related health effects on the eye and immune system is independent of skin type.
