UV Index

The UV Index is a useful tool to help people take steps to reduce their exposure to solarUV radiation.  It is reported as a prediction of the UV level at noon, although the actual UV level rises and falls as the day progresses.

UV Index Protection GuideThe UV Index represents the amount of skin damaging UV radiation reaching the earth’s surface at any instance of time.

 

  • The UV Index level may vary on any given day.
  • There are three types of UV radiation: UVA, UVB and UVC.
    • UVA is principally responsible for aging of the skin.
    • UVB and UVA are key contributors for skin cancer.
    • UVB is responsible for burning.
    • UVC is blocked by the ozone layer
  • Too much exposure to UV radiation and the number of sunburns experienced, especially during childhood, increases your risk of skin cancer.
  • Exposure to UV radiation enables the body to  produce vitamin D, an important nutrient in bone development and maintenance.  A balance is  required between UV radiation exposure for vitamin D production and protecting the skin from damage and skin cancer.
  • Most people achieve adequate vitamin D levels through UVB exposure during typical day-to-day outdoor activities.  In summer you just need to expose your face, arms and hands or the equivalent area of skin for a few minutes of sunlight each day on either side of the peak UV periods.  Naturally dark skinned individuals need longer exposure. 

The Bermuda Weather Service now posts a daily UV risk.

Check the UV Index when:       

  • Planning or participating in an outdoor activity or event
  • Involved in recreational activities such as running, swimming, cycling or team sports
  • Watching a spectator sport, such as tennis or cricket
  • Working outdoors, or have responsibility for out-door workers, or
  • Responsible for children or adolescents and their outdoor activities.

When SunSmart UV Alert times apply, you need to be SunSmart during the period indicated.
