Moisture content
Fabrics offer less protection from UV radiation
when wet. The level
of protection will depend
on the type of fabric
and the amount of moisture
it absorbs. To reduce the effect of the moisture,
take dry clothes to change into or if dipping in
and out of the water, choose a fabric that
provides effective protection from UV and that
will dry quickly.
Caring for your clothes
Washing new clothes
can improve their sun
protection, especially
when made of natural
fibres
such as cotton, by
shrinking gaps in the
structure. However, old, threadbare or faded
clothes may offer decreased protection over
time.
UV absorbers
Some clothing is treated so it can absorb more
UV radiation. Check the clothing label to see if
your clothes have been treated and ensure you
follow the care instructions.
