Over a year since the new crown epidemic, masks have become a must-have for everyone to go out. I have worn masks for so long. Have you ever wondered why most masks are blue?
Although the masks on the market come in a variety of different colors, such as white, pink, and black, the masks for the Spring Festival Gala are still red with patterns, but the medical staff are basically all blue masks. You don't understand it, it doesn't matter if you don't understand, I understand.
There are many benefits to using a blue mask
The use of blue in modern medical surgical masks does have many benefits. In the early years, the medical masks were white, but later it was discovered that the combination of white coats and white masks reflected too much light under the lights, which easily caused visual fatigue of medical staff and patients.
This piece of whiteness is as pure as heaven...
The use of a cooler light blue for the mask can not only reduce reflections, but also make the color less monotonous, and it is not easy to make people feel impetuous, but it will help calm the mood. In addition, medical staff may have a lot of blood and secretions in the face of various patients. A blue mask stained with blood will not be as conspicuous as a white mask stained, which can reduce the tension in medical treatment.
Also, medical surgical masks are layered. Why do you want to layer? For the simplest example, you have done a urine test before, and you will get it if you are not careful.
Medical staff have to hold it for inspection, if you accidentally get it on the mask...so waterproof mask is very important! The outermost layer of the medical surgical mask is the waterproof layer, and it also has a certain anti-bacterial function (of course, it is strictly for protecting the virus, you must wear an N95 mask), the middle layer has a filtering function, and the inner layer is directly close to the mouth and nose. Since we have divided the front and back, we have to let everyone distinguish it, so the outer layer of the mask is made blue and the inner layer is made white, so that it is not easy to wear it backwards.
