Isn t it possible to wear an umbrella with UV protection in summer to prevent tanning?

Wearing an umbrella that is not UV protection in the summer can prevent tanning. Ways to prevent tanning:

1. Apply sunscreen.

In summer, the sun becomes scorching, and sunscreen is an essential sunscreen, so you should apply sunscreen thirty minutes before going out, so as to achieve a good sun protection effect.

2. Reapply sunscreen in time.

Sunscreen can form a protective film for **, but this protective film can not maintain a day of sunscreen, the general sunscreen effect is maintained at 3-6 hours, so it is necessary to make up the sunscreen in time, so as to prevent tanning.

3. Use a parasol when you go out.

In this way, the umbrella should be a must-have for girls in their summer bags, and it can play a role in shading and ultraviolet protection outdoors to avoid direct sunlight from causing damage.

Yes. The most important way to avoid tanning is physical sun protection, and a parasol is a good way to block UV rays. The reason for tanning is that the UV radiation on it promotes the production of melanin.

So the most important thing about suntan protection is to block UV rays. However, just applying sunscreen will not block UV rays for a long time, as it cannot be applied to every corner of the sunscreen, and the sunscreen ingredients will gradually lose their sun protection over time. Therefore, choosing a parasol with a high sun protection index can effectively block ultraviolet rays and achieve the purpose of sun protection.

Sun umbrellas are one of the must-have sunscreen products for many of us in summer, but many people don't know whether sun umbrellas can put ultraviolet rays and whether they have sun protection effects. Let's take a look at the sun umbrella.

1. It has a certain effect

Sun umbrellas have a certain effect of protection against ultraviolet rays。Generally, the sun umbrella will use protective fabrics such as silver glue, pearlescent cloth, and satin, which can block part of the purple reeds. And someOrdinary sun umbrellas without UV protection coatings also have a certain defensive effect, but the sun protection effect of this umbrella will be affected by the color of the umbrella

2. Don't cover the rain too often

Many people who accompany the stall in the summer often use the sun umbrella as both a parasol and an umbrella for convenience, but in fact, this is not very advisable. Because sun umbrellas with shading effect usually use thicker and special anti-ultraviolet fabrics, and when it rains, rainwater often uses substances that corrode the surface of the umbrella and affect the sunscreen effect, so everyoneIt is best not to use a sun umbrella to cover the rain very often, it's okay to have an occasional emergency. In additionAfter using a sun umbrella to cover the rain, it is best to rinse the umbrella with water and then dry it

3. How to choose an umbrella

When buying a UV-resistant sun umbrella, it is better to choose polyester fiber as the raw material, because among the untreated fibers, polyester has the best UV resistance. In addition to that,When buying a sun umbrella, you also need to look for the UV protection labelGenerally, when the umbrella has UPF 50, it means that the performance of this umbrella to protect against ultraviolet rays is very good, and its identification level is usually UPF50.

Of course, the fabric and coating of the sun umbrella will affect the sun protection effect. When choosing a sun umbrella, it's a good idea to look at the sun protection factor on the label before buying. Will the posture of playing the umbrella affect the sunshade effect?

According to the way people are used to playing umbrellas in real life, the reporter locked the target of the shot on the face, and then simulated two postures: standing up and shouldering. Compare the two canopy positions which has better sun protection.

Through experiments, when people adopt an upright position holding an umbrella, the umbrella has a wider coverage area, and in addition to blocking direct sunlight, the surrounding environment also reflects less light to the face.

The darker the color of the umbrella, the better the UV resistance: the ultraviolet transmittance of the black umbrella is 5%; The ultraviolet transmittance of navy blue, red, dark green and purple umbrellas is 5%-10%; Red, light green and white umbrellas have UV transmittance of 15%--20%. As a result, darker canopies are more UV-resistant.

The effectiveness of UV protection is related to many aspects.

In terms of fabrics, the effect of silk, cotton and nylon is poor, and the effect of polyester reed branches is good; In terms of weaving methods, satin fabrics have the best UV resistance, such as satin fabrics, followed by twill and plain weaves; The darker the color, the better the sun protection. Under the same conditions, the darker the fabric, the better the UV resistance. In contrast, black, navy, and dark green have better UV protection than light blue, light pink, and light yellow.

The *** of the silver glue is bad. The silver glue of the sunscreen umbrella produced by the manufacturer with good technical conditions is not easy to fall off, while some cheap sunscreen umbrellas are only coated with a layer of silver on the umbrella surface, and they will fall off after a few sunbaths. Some people seem to feel cooler in silver glue fabrics, mainly because the silver rubber fabrics are thick, have low light transmittance, and do not feel heat.

Silver glue fabric is also the first generation of fabrics used as sun umbrellas. At present, the light and ultra-thin silk fabrics on the market have the characteristics of lightness, transparency and bright colors due to the thin warp and weft. The other is fat silk.

The warp and weft threads are thick and thin, creating a kind of refraction and giving people a crystal-like feeling.

Look at the logo, the label should not only have the national standard number (GB T 18830-2009), but also have UPF, UVA transmittance, as well as the manufacturer's name, address, product quality inspection certificate, production date, etc., the product quality with complete marks is more guaranteed.

Look at the tightness of the fabric: The tightness of the umbrella fabric is another important factor affecting the UV resistance of the umbrella. The tighter the fabric, the worse the light transmittance and the better the UV resistance. Observe the open umbrella cloth against the light, the weaker the light, the tighter the fabric.

If it is to be safe, polyester material can be chosen. The thicker the fabric, the better the protection provided. From the perspective of the effect of sunshade and anti-ultraviolet rays, it is recommended to choose a parasol with a double sunshade cloth on the surface, because of the thermal effect of the partition between the two layers, the temperature under the umbrella is difficult to accompany the line to rise, which can protect our **.

It has a sunscreen function, which can protect against ultraviolet rays, and most of the ultraviolet rays can be blocked, so it is not easy to be sunburned.

Willing to talk about clearing the dust, including Zen and closing yes; However, it is impossible to guarantee 100%, because its material and processing technology requirements have sunscreen function, but it cannot be completely effective.
