In mid-August, when the temperatures outside are unbearable, many of us move toward white clothes. Why? First, because they sweat me sweat more efficiently. And secondly because most of the white clothes are loose. The last thing we need in the hot summer days is a body dress. Finally, we stick to the theory that white clothes reflect the sun's rays - or heat. Or light?
Whatever the scientific or pseudo-scientific rumor is the one that circulates in the summer, we are not the only ones we have heard and applied. To shed light on this theory, Rhett Allain, professor of physics at Southeastern Louisiana University, told.
"White looks like colder color," Alla starts. "Try an experiment. Get a white paper and leave a black paper in the sunlight. Wait five minutes and then rub each sheet on the page. Believe me that the black paper is hotter than white. "
White light, Allah explains, is the combination of all colors, while black is the lack of color. "This means that the white paper reflects the whole light, while black sucks and warms."
But some other studies say black garments keep us cooler than white. For example, the Bedouins wear black clothes to survive the heat in the Sinai Desert.
In theory: "When the body heats up, it radiates energy (in the infrared spectrum)," Alla says. "If you wear white clothes, this body radiation is reflected back in your body and exudes you even more, while your black clothes do not reflect it back."
The answer to the question in the title is how simple, so complicated: it depends. Well, what if you wore a white, thick, thick blouse? In this case, the body does not transmit energy through radiation but through thermal transmission because it has contact with the fabric. It's better to wear a black, thin, loose blouse.
"How does someone feel in the heat depends on many things: the color of clothing, in the narrow or broad, how loose it is, if there is puhi, sun or shade," Alla says. "For your good, wear what makes you feel comfortable. Choose loose and soft fabrics, like cotton and linen in light colors. "
