Although the early autumn sunshine is less sharp than that of summer, it is no less scorching. Therefore, even when the weather turns cooler, we should not relax our sun protection efforts. The Popular Health Network reminds you that if you choose the wrong sun umbrella, your efforts may be in vain. The following types of umbrellas have poor sun protection effects. Polyester umbrella cover Cheap parasols are often made of polyester and other materials, which are inherently thermally conductive. Long-term use will cause the temperature of the small space under the umbrella to rise, causing the scalp to heat up. It is recommended to choose a parasol made of natural materials such as cotton, linen, and silk. Light colored umbrella Light-colored umbrellas allow ultraviolet rays to pass through easily, and even after anti-ultraviolet treatment, the effect is not good. It is recommended to choose a dark-colored parasol such as black. Umbrella with light inner color Many people ignore the inside of the umbrella. In fact, in addition to direct sunlight ultraviolet rays, ultraviolet rays reflected from the ground can also burn the skin. Therefore, try to choose a parasol with a dark color such as black on the inside of the umbrella. Single layer umbrella From the perspective of sunshade and UV protection, it is best to choose a parasol with a double-layer cloth cover, which can use the heat insulation effect of the space between the two layers of cloth to prevent the temperature under the umbrella from rising easily, thereby protecting the skin. At the same time, double-layer cloth is better at filtering ultraviolet rays than single-layer cloth. |
