Sunscreen can be troublesome and does not always protect the skin enough. There is an alternative sometimes more durable and safer: the fabric. What he promises and what he enjoys
Sunscreen is an excellent invention. Because it protects the bare skin against harmful UV steel. But it also has its drawbacks: the greasy film on the skin magically attracts grains of sand, especially on the beach. You must use regular cream to get sunscreen. Hides exiting empty hands are exposed to the sun without protection. And some of the ingredients, such as nanoparticles, that you really do not want to have on the skin. In addition, creams or sprays usually contain substances that are also problematic for the environment – and throw themselves directly into the sea while bathing – or challenge the water treatment plant after the shower.
We have come to the conclusion that there has long been a totally safe and effective alternative: textiles. After staying in the shade or at home, long-sleeved clothing and wide-brimmed headgear offer the most reliable protection. Anyone planning a long stay in the sun in the sun then has to sufficiently smooth out the remaining areas, such as the nose, ears, neck, neck or back of the hand.
Black clothes protect better from the sun than from white
In principle, all finely woven textiles protected against solar radiation. However, there are differences: the sun protection factor is high, the more the wires are intertwined. Since synthetic fibers are thinner than cotton, synthetic fiber textiles such as polyester generally have a superior protective effect. In addition, the color does not matter. White clothes do not heat up in the sun. But there is still about 40% of the harmful UV rays on the skin. Black clothes heat up, but at the same time absorb about 97% of the radiation.
UV protective clothing with UPF and UV standard 801
At the same time, some manufacturers offer clothing with special protection against UV rays, especially in children's clothing. This protection is obtained mainly with fiber type and dense weaving, and rarely with special chemical equipment. Since some manufacturers pay well for UV protection, potential buyers need to pay attention to a significant standard.
An Australian standard is the UPF (Ultraviolet Protection Factor). It is comparable to the sun protection factor of sunscreen. This means that textiles with UPF 30 allow us to stay 30 times longer in the sun than without protection. However, the figure does not say whether this sun protection factor is actually observed under practical conditions. For example, in heavy use or when it is wet. The same goes for the European standard EN-13758.
The 801 standard UV quality label is more reliable. According to this standard, the garments tested keep their promise, even if they are wet, stretched or washed several times, for example. In each case, only the lowest value of a textile obtained is certified.
