The UV Index is a useful tool to help people take steps to reduce their exposure to solar UV 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.

• The UV Index level may vary on any given day
• 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. 

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

The Bermuda Weather Service now posts a daily UV risk.

• Planning or participating in an outdoor activity or event
• Involved in recreational activities such as running, swimming, cycling or team sports
