Dark clothes and hats, such as black, absorb more sunlight and have the worst sun protection effect. However, the light-colored clothes and hats have a high sunlight reflectivity of about 85%, which absorbs less sunlight radiation and has a better sunscreen effect. Therefore, the sun hat bought for children should be light-colored, and boys can choose sky blue and light green; Girls can choose pink and goose yellow.

Sunshade material

Generally, the materials of sun hats are nylon, cotton, cotton and linen blended yarn hats and straw hats. The key to the sunscreen effect of hats lies in the density of materials, which can be distinguished by naked eyes.

Comparatively speaking, mesh gauze hats and straw hats have the highest material density. Although they are cool, they have the worst shielding effect, and the effect of sun protection can be imagined. The sun protection coefficient of cotton hats is as high as 1000 or above, but the material is thick, so it is particularly easy to sweat in summer. The nylon cap is light and thin, which is very suitable for summer use and has a good anti-ultraviolet effect.

In addition to the material, you should choose the sun hat according to your actual situation. If you use it frequently, such as people working outdoors or traveling, you should choose a hat with a wide edge; For people with short necks, the sun hat with half and narrow sides is the best; Women with long hair can get the effect of hair care by wearing a sun hat with wide edges all around.
