Which sun umbrella is good at protecting against UV rays?

Ultraviolet rays are particularly strong in the hot summer, so in order to avoid ultraviolet damage to the skin, many people choose to use parasols to block the sun, but faced with so many varieties of parasols, they don’t know how to choose. The more expensive the parasol is, the better the sun protection effect is. Generally speaking, the price can only be linked to the quality of the parasol, and has no correlation with the intensity of ultraviolet resistance. There is also a kind of umbrella that can be used for both rainy and sunny days. This kind of umbrella will not have any sun protection effect after being washed by rain. It is recommended to look at the protection label on the umbrella.

First, look at the label. It mainly depends on the protection index, that is, the UPF and UVA values. Only when the UPF is greater than 40 and the UVA transmittance is less than 5%, can it be called an anti-UV product. The larger the UPF value, the better its anti-UV performance. Generally, most products on the market are marked as "UPF50+", which is sufficient for protection.

Second, look at the color. When the fabric is the same, dark-colored umbrellas have better UV protection effects. The biggest difference between parasols and other umbrellas is that they have an anti-UV coating to prevent the penetration of ultraviolet rays.

Third, look at the fabric. The thicker the umbrella surface, the tighter the fabric, the better the UV resistance. Compared with cotton, silk, nylon and other fabrics, polyester is more sun-proof. If you want to know how effective a parasol is in protecting you from the sun, try it out in the sun. Umbrellas with darker shadows and lower light transmittance have the best sun protection effect.

Generally speaking, the darker the color of a parasol, the better its UV protection effect. The coating on some parasols will fall off after a long time of use. Therefore, it is not recommended to choose an umbrella with coating on the surface. It is recommended to choose an umbrella with coating inside, which can not only keep the coating for a long time without affecting the appearance of the umbrella. In addition, you can take sun protection measures and apply sunscreen or isolation cream. The double-layer sun protection effect is better.
