Is it cool to wear dark clothes or light clothes in summer?

But the color of the sunscreen effect is almost the opposite: an ordinary T-shirt is better than any sunscreen, and the SPF value is about 15 ~ 30, which can isolate 95% of ultraviolet rays, but remember that clothes lose their sunscreen effect when they are wet.

As far as color is concerned, the darker the color, the higher its anti-ultraviolet performance, such as black. As far as texture is concerned, among chemical fibers, polyester > nylon > artificial cotton and silk; Among natural fibers, flax > hemp > cotton silk. In addition, the place where the T-shirt can't stop should be protected from the sun.

According to the latest research results in Britain, dark red or navy chemical fiber clothing is the most ideal sun protection clothing.

People usually like to wear light-colored clothes in hot summer, but they don't know that light-colored clothes are refreshing, but long-term exposure to sunlight and ultraviolet rays can lead to skin cancer, especially dazzling white cotton clothes, which often contain fluorescent whitening agents and reflect harmful light to people's unprotected faces. On the contrary, dark clothes such as red or navy are much safer.

A research report of the British Radiation Protection Committee pointed out that the worst sunscreen effect is light yellow cotton fabric, with an SPF of only 7, and the sunscreen effect drops to 4 after soaking. In addition, the SPF of beige cotton fabric is 9, and that of white cotton fabric can reach 33-57, but clothes made of this material may still make people with sensitive skin get sunburned.

In view of this, scientists suggest that people should change their previous habit of wearing light-colored clothes and wear more dark-colored chemical fiber fabrics when they go out in summer with relatively strong ultraviolet radiation.
