Why Sun Protective Clothing Is So Special
UPF Clothing (also called Sun protective clothing) is not just for people concerned about
skin cancer. It is not just for those whose sun-worshipping days
are over. No, throwing on a sun protective shirt with a UPF 30+
value is a proactive decision wise consumers are making simply to
live healthier. Sun-protective clothing is an investment in oneself.
It is preventative, similar to dedicating a portion of one's day
to diet or exercise.
With 1.3 million Americans expected to be diagnosed with skin cancers
this year (including deadly melanoma), health professionals are
starting to drop the word "epidemic" in sun vs. skin reports. Aside
from cancers, excessive ultraviolet radiation comes with a slew
of consequences, including premature wrinkling, immune suppression,
cataracts, and the "fever blister."
Although the greatest defense against the sun is to simply avoid
it, especially during the hours when the UV index is at its highest,
this is not always possible or a popular choice. According to a
recent article in the BBC News, a team of Swiss researchers reported
that sun-protective clothing is the healthiest option aside from
simply staying out of the sun. UK scientists agreed in urging that
sunscreen should only be used as a "last line of defense."
Were these scientists sunscreen haters? Of course not. They simply
found (in the course of their 500 studies of how people protect
their skin around the world) that sunscreen was virtually ineffective.
This is due mostly to consumer misuse. People put on sunscreen only
after they notice themselves turning red or use it as an excuse
to stay in the sun all day. Also, of those who do apply it, most
neglect to use a liberal enough amount or coat the sunscreen evenly
across the skin's surface.
More foolproof and more protective are technologically advanced sun-protective clothes. Although all clothing would logically seem
to be sun-protective, the degree to which this is true varies greatly
depending on the type of fiber, fabric thickness, color, and tightness
of weave/knit. For example, an ordinary a summer weight light-colored
cotton shirt may afford a sun-protection-factor (SPF) of 6. This
number is decidedly insufficient to be spending all day outdoors.
What happens when the sun's rays strike a fabric's surface? The
ultraviolet radiation is broken down. A portion is reflected from
the fabric, another portion is absorbed, and the remaining portion
reaches the skin.
Studies performed by Gambichler et al. showed that while 70% of
wool, polyester, and fabric blends may provide an ultraviolet protection
factor (UPF) of 30 or greater, less than 30% of cotton, linen and
rayon provide up to a value of 30. Fabrics colored black, navy-blue
and green fare better than lighter colors of the same fabric. Also,
dry fabrics protect more than do moist or wet.
On the basis of this study, conducted in 2000-2001, scientists
concluded that the average consumer, even if armed with this knowledge,
would be confused as to what garments to purchase. In response,
a standard guide was developed for the labeling of ultraviolet protective
textiles called Ultraviolet Protection Factor or UPF.
The UPF method is the standard technique for measuring the protective
value of textiles. American producers are not required to follow
these standards; if they do they do so voluntarily or out of a sense
of ethics.
UPF is a measure of total ultraviolet radiation blocked, both UV-B
and UV-A. The measurement of UV-A protection in clothing offers
an improvement over the traditional SPF rating of sunscreens, which
measures only UV-B radiation. The total radiation penetration is
measured by a radiometer. If a garment has a UPF factor of 50 attached
to it, this means that just 1/50th of the sun's radiation will reach
the skin.
As studies show, aside from staying indoors, UPF clothing offers the best form of protection from the sun's harmful ultraviolet
rays. The good news is that you don't need to sacrifice fashion and comfort to keep you and your loved ones safe under the sun.
