Whenever the temperature drops, the discussion about long johns gradually heats up. One of the more controversial issues is what the small holes on boys' long johns are used for? Many people think that this is used for going to the toilet, but it is not, because such a design structure would seem a bit unreasonable. Cooling and heat dissipation The holes in long johns are really small. The width of the holes in some men's long johns is only wide enough for a thumb to pass through. Such a small hole is not only inconvenient for going to the toilet, but may also cause excrement to spill on yourself, greatly affecting the operation. Furthermore, when wearing long johns in winter, the three inner layers and the three outer layers are clothes that tightly wrap the torso. Instead of unzipping the zippers layer by layer and then going to the toilet through the small holes in the long johns, it is better to just untie the belt. As for the real purpose of the small holes in long johns, we have to mention cooling and heat dissipation. The male body structure is very magical. In cold weather, no matter how cold the hands and feet are, the parts corresponding to the small holes in the long underwear can always feel warm. Because this part of the male body has the highest temperature and is least susceptible to external influences. If you wear too thick clothes in winter and the thermal insulation of the autumn johns is too strong, it will easily cause the temperature of this part to be too high. Sperm cells are very fragile and will die in large numbers once the temperature is not suitable. Therefore, if the temperature is too high, the skin will dissipate the heat by secreting sweat to ensure the survival of sperm cells in the male body. If clothes are wrapped around the skin at this time, it will easily cause sweat and heat to accumulate in the body, leading to symptoms. But in order to keep warm, autumn johns cannot be made of breathable materials, otherwise it would be putting the cart before the horse, and they cannot be designed in the form of shorts. So after comprehensive consideration, it would be most appropriate to make a small hole in the long johns. In addition, the small holes in men's long underwear can allow air to circulate in the covered area, reducing the probability of skin diseases such as rashes, eczema, and peeling. After all, in the cold winter, people wear thick clothes, making it difficult for the skin to come into contact with the outside air. Germs can easily accumulate in the skin, leading to the occurrence of a variety of skin diseases. Some friends may wonder why there is no opening on women's long johns? Don't women need to dissipate heat? Pay attention, women not only do not need to dissipate heat, but also need to gather heat, because the middle part of the female body is the most sensitive place and also goes through menstruation. Every time your period comes, there will be additional heat loss. Therefore, during special periods, some women will buy warming patches to keep warm and relieve discomfort during menstruation. This is also the reason why many men ask their girlfriends to drink more hot water to make them suffer from menstrual cramps. This is not a straight male behavior! Keeping the middle part of a woman's body warm has many benefits and no harm. Distinguish between positive and negative and gender In the early designs of long johns, the design structures of men's and women's long johns were the same, and men and women could wear them interchangeably. Later, designers discovered that there are considerable differences in the structure of male and female buttocks. If a similar structural design is used, the experience provided to both men and women will not be very good. Therefore, in order to differentiate between men's and women's long johns, designers made subtle changes to the hip structure. But the problem also arises: when consumers buy long johns in shopping malls, how can they distinguish between men's and women's styles? Such subtle changes make it difficult for consumers to distinguish a style that suits them. Even if there are labels in the mall, it is easy to confuse them with other people's autumn johns after wearing them at home for a while. After all, as underwear, long johns are relatively monotonous in color, and even today they can easily be confused with other people's long johns, let alone in the past. Similarly, there is no obvious difference between the front and back of long johns. Some people take them home and wear them for a long time before realizing that they put them on backwards. In order to solve this problem, the designer opened a slit in the men's long johns so that consumers can distinguish between men's and women's styles and identify the front and back when purchasing. Why didn’t the designers use some other way to distinguish the two features, instead of using small holes? Because there are many benefits of small holes. In addition to the three points mentioned above, small holes also have other wonderful uses. Lifestyle When drying long johns, have you ever encountered this problem? Some men's long johns have too large waists, and they can easily fall off the clothesline when hung out to dry. As a result, a pair of long johns has to be washed several times during the drying process, causing unnecessary trouble to people. In fact, everyone’s way of drying clothes is wrong. You can just make use of the small holes in the autumn johns and put the clothes drying rack through the small holes to dry clothes. It will not only look beautiful but also be difficult to fall off. When drying, this small hole can also provide good air circulation, allowing the autumn johns to dry faster. Women's long johns are mostly tight-fitting clothing. Considering that women's waists are smaller than men's and their skin is more sensitive and aesthetically pleasing, the materials used for women's long johns are different and are less likely to fall off during the drying process. It can be seen that the small holes in men's long johns are very useful in life. Although it is not known whether this was taken into consideration in the original design, at least its practicality is beyond doubt. Increase space The last function of the holes on long johns is to increase space. This is determined by the special physiological structure of men. Because many long johns are tight-fitting, they will inevitably squeeze certain parts, which is not good for health. If there are no small holes to expand the space on the long johns, men will feel quite uncomfortable when putting on the long johns. If the steps are too small, it will look a bit "feminine", and if the steps are too big, it will easily be pulled, which will damage the delicate image. When long johns were first invented, designers did not take this factor into consideration. For the sake of their image, men sometimes had to hunch over and move slowly. Until 1914, men's long johns had no holes. At that time, long johns were a kind of one-piece suit that tightly wrapped the male body, even the wrists were tightly wrapped, making it very difficult to wear and very uncomfortable. So although this structure is indeed conducive to keeping warm, it has also been complained by many consumers. So the designer opened a small hole in the middle of the long johns. It was not until 1918 that people gradually came to believe that autumn trousers and autumn clothes should be made separately, and then they distinguished between autumn trousers and autumn clothes. After several years of improvement, the trend of long johns has finally emerged in the world, and in some developed countries, it has a huge market. Because in the early 20th century, human heating technology was not as advanced as it is today, people usually relied on stoves for heating, and at this time long johns became an important tool for keeping warm. Later, with the advancement of technology, Europeans and Americans noticed that long johns were not so beautiful and fashionable. Coupled with the improvement of housing conditions, Europeans and Americans gradually abandoned long johns. For example, Canadians no longer have the habit of wearing long johns. In the winter, they usually wear a pair of plush pants. If they go out, they will add another pair. This is both convenient and beautiful. Long johns are very popular in our country, but this has also caused controversy. Because long johns are no longer that important in Europe and the United States, should we be like Europe and the United States? There is actually nothing controversial about it. Just wear it if you really can’t stand the cold. The body is the most important thing. What do you think about this? Welcome to leave a message in the comment area.
