Most weather reports include an update on the UV Index, but how many of us know what the UV Index actually means or how to interpret it? The UV Index is in fact an extremely important weather-related factor to consider, and can help prevent you from getting burnt.

The ultraviolet index, or UV Index as most of us know it, is, according to Verywell Health, a scale relating to the intensity of ultraviolet radiation from the sun. As IOL explains, Ultraviolet wavelengths of sunlight are comprised of UVB and UVA rays, both of which lead to the damage of skin cells and are thought to cause skin cancer. UVB is the cause of sunburn, while UVA contributes to premature skin aging.

The scale comprises several levels of intensity, going from 1 to 11+. These levels are grouped according to their intensity, and each group is represented by a specific colour.

Index Number Level of Intensity Colour Code

1 to 2 Low Green

3 to 5 Moderate Yellow

6 to 7 High Orange

8 to 10 Very High Red

11+ Extreme Violet

A lot of factors can contribute to the scale of the UV Index. These include the season (the index is at its highest during spring and summer), the time of day, ozone levels, cloud cover, altitude and earth surface characteristics such as snow, water and sand, each of which reflects a certain percentage of UV radiation.

The UV Index is a useful tool that will remind you always to protect yourself against the sun. It’s a constant necessity, which is why you should carry EezySun’s small and easy-to-use sunscreen snap sachets with you wherever you go. They’re available at leading Clicks and Spar stores nationwide.
