“Ultraviolet (UV) radiation is a type of radiation that is produced by the sun and some artificial sources, such as solariums. The sun’s UV radiation is the major cause of sunburn, premature ageing, eye damage and skin damage leading to skin cancer . However, it is also the best natural source of vitamin D.
The sun protection times can tell you whenever UV levels are forecast to be 3 or higher. This makes it easier to know when you do and don’t need sun protection. These times are forecast each day by the Bureau of Meteorology.
You can find the sun protection times for your location on the SunSmart widget below or at the Bureau of Meteorology website .”
