Does wearing black clothes in summer protect against the sun? Will I feel hot if I wear black clothes?

In summer, many people go out and take a lot of sun protection measures, such as applying sunscreen. However, covering with clothes is the most basic and better method, which can effectively avoid tanning. So, what clothes are the most sun-protective in summer? Does wearing black clothes protect against the sun in summer?

Does wearing black clothes protect against the sun in summer?

Sun protection. The UV transmittance of black clothing is only 4%, while light-colored clothing provides very poor protection against UV rays. Light-colored clothes, such as white, actually emit infrared rays, which is not conducive to the heat dissipation of the human body. The traditional understanding of "white reflection" refers to reflecting heat but cannot block ultraviolet rays.

Why black clothes protect against UV rays

1. Anti-ultraviolet performance > other colors. Dark clothes are more sun-proof. Purple and black absorb ultraviolet rays stronger than other colors. Light-colored clothing provides very poor protection against UV rays, especially cotton clothing containing fluorescent brighteners, which will reflect harmful light onto the unprotected face; while translucent and hollow clothing has basically no sun protection effect.

2. Black clothes can absorb light of various wavelengths, including ultraviolet rays, but black also absorbs heat.

3. The UV transmittance of black cloth is only 0.9%, and its anti-UV effect is amazing.

4. White reflects all colors, but this does not mean that it will bounce off ultraviolet rays like a protective shell. On the contrary, when ultraviolet rays are scattered around the body, due to the rebound of white, all ultraviolet rays will be radiated on the skin, inducing the production of melanin to absorb ultraviolet rays to protect the tissues within the skin.

Is it hot to wear black clothes in summer?

Dark clothes are actually very cool. Harvard University in the United States once conducted an experiment, and the results showed that wearing dark clothes in summer is cooler than wearing white clothes. Black clothes absorb more heat than white clothes. The absorbed heat can form convection power inside the clothes, taking away sweat and part of the heat on the skin surface, so the body will naturally feel cool. Of course, black clothes should be chosen to be looser, so that the "convection" can be enhanced and the coolness of the clothes can be increased.

In addition, when wearing black clothes indoors or on cloudy days, there is less sunlight at this time, and black will not exert its nature of absorbing heat quickly. Instead, it will only exert its ability to dissipate heat quickly, quickly dissipating heat from the surface of the skin, making people feel a lot cooler, which is naturally cooler than clothes of other colors.

What clothes are the most sun-protective in summer?

In contrast to light-colored dyes, dark-colored dyes absorb more UV rays. The darker the color, the higher its UV protection performance and the better its protective effect on the skin. For example, black and navy blue are the colors that are best at blocking ultraviolet rays after red. Although dark-colored clothes absorb more heat, the absorbed heat can become the driving force for air convection inside the clothes. Just like in the summer afternoons, when the heated ground easily forms local convection and even brings thunderstorms, the air convection inside the clothes can also take away sweat and some heat from the skin surface, making the body feel naturally cool. Red is the color that can best block ultraviolet rays. Sunlight is divided into visible and invisible light. Visible light refers to light that can be seen by the naked eye; invisible light refers to light that cannot be seen by the naked eye, such as ultraviolet rays, infrared rays, etc. The ultraviolet rays are the most harmful to the human body in sunlight. The red light wave is the longest, which can absorb a large amount of ultraviolet rays in the sun, protecting the skin from harm, preventing skin aging and even cancer, while the effect of other colors is weaker. So wearing red clothes in summer is the best way to protect against the sun.
