Before you read just a warning, I am going to geek out a little on the acronyms but I have kept them to a minimum and for all the visual people out there (like me) I have also included an infographic.
SPF (Sun Protective Factor) and UPF (Ultraviolet Protection Factor) are both official measurements of UV (Ultraviolet) protection. This takes into consideration UVA and UVB rays. The level (or number) is determined by lab tests and aligns with the relevant international standards. Just so you know there are 3 different international standards, Australian/New Zealand (AS/NZS), American (AATCC) and European (ASTM)
When shopping for sun protective clothing, always make sure it specifies the UPF rating. UPF (Ultraviolet Protection Factor) applies to clothing and fabrics.
There is no such thing as SPF rating on clothing or accessories. SPF (Sun Protective Factor) only applies to creams, e.g. moisturiser, sun cream, beauty products etc.
The number associated with SPF or UPF describes the level of protection of UV filtering from the sun that is provided. 50+ is the highest and offers 98% protection.
Covering your self from the sun in a regular cotton t shirt will not protect you from the UV rays.
Popular UPF rated clothes include swimwear, rash guards and hats.
Regular washing of your UPF items will not decrease the level of protection, however, some harsh, super powerful detergents will.
Because your skin absorbs sun cream, you have to apply SPF suncream every hour to have continual protection from the sun
UPF clothing protects the body all day from UV rays by both, absorbing and reflecting the rays.
Most people forget about protecting their legs and that’s where the body absorbs most of the harmful UVA and UVB rays
