Shade

 Exposure to UV radiation can be reduced by avoiding the midday sun between 11-3

 

The intensity of the UV light varies considerably throughout the day.

 

Seeking shade between 11-3 provides good protection from the sun and reduces the amount of UVR (Ultra Violet Radiation) you receive by 75%.

 

There are two types of shade:

  • Natural shade

  • Man made shade

 

Natural Shade

Natural shade includes trees and shrubs which have wide spreading dense foliage enabling effective protection from harmful UVR.

 

Man Made Shade structures

Man made shade structures can be made from a variety of materials such as glass, fibre glass, timber, sheeting, steel roofing etc.

For the man made structures to be effective:

  • Shade must fall in the right place at the right time of day

  • Provide at least 94% reduction in direct UVR

  • Be attractive/aesthetically pleasing

  • Be comfortable and safe in all seasons

Complete protection from UVR is not offered by structures such as umbrellas and canopies due to the rays being able to penetrate the material.

UVR can also be reflected up from surfaces such as concrete, sand, water and snow.

 

Handy hint..........

 

A way to identify when to seek shade is to use the shadow rule -

 

When you look at your shadow, if it is short – seek shade!!
