Shade provides good protection from the sun and can be easy for people to use. Staying in the shade and out of the direct sun can reduce the amount of solar ultraviolet radiation (UVR) you receive by 75 per cent or more.
Types of shadeShade can either be natural, man-made or a combination of both. Natural shade provided by trees or shrubs with dense, wide spreading foliage provides effective protection from harmful UVR.
Shade materials used in man-made shade structures include: glass, polycarbonate and fibreglass sheeting, canvas or other tightly woven cloths, PVC shade cloth, timber and steel roof sheeting.
To be effective, shade must:
- fall in the right place at the right time of the day
- provide at least 94 per cent reduction in direct UV radiation
- be comfortable in all seasons and attractive so people will use it

Shade structures such as trees, umbrellas or canopies do not offer complete sun protection. UVR can scatter in the atmosphere and reflect from surfaces such as water, sand and concrete. Always use in combination with other sun protection measures: clothing, hat, sunglasses, and sunscreen.
