Why do my feet sweat when wearing thick socks in winter?
In winter, many people will sweat their feet if they wear thick socks,They feel that the socks are cold, but they are not warm enough to wear thinner socks. Then, why do feet sweat?
1. The reason for your feet sweating is that your socks do not absorb moisture, your shoes are not breathable, and the sweat in thick shoes is not easy to evaporate, so shoes and socks feel wet in winter. Many people think that the thicker the socks, the better the warmth, but if the socks are thick but not moisture-absorbing and breathable, they are easy to get wet. A large amount of moisture will squeeze out the air in the socks fiber, because of the lack of air, which is an excellent heat insulator. When the socks are wet, they will make the soles of the feet cool.
2. In winter, the indoor temperature is high, If the shoes and socks are too thick and tight, it is easy to sweat. If the foot sweat is not released in time, it will be absorbed by the footwear, which will not only breed bacteria and cause athlete's foot. In a low temperature outdoor, when the moisture in the shoes is cold, the feet will feel colder. In addition, if the footwear is too tightly wrapped, it will also affect the blood circulation of the feet, which is also the reason why the body does not feel warm.
How thick socks to wear in winter
Wool socks with the strongest heat retention are followed by rabbit fur socks, but both socks are more prone to shed hair. You can often see words such as "80D" and "110D" on the packaging of velvet socks on the market. Experienced people say that the higher the D number, the thicker the socks. Indeed, D refers to Denier, which is the fiber's fineness unit. The higher the D number, the higher the relative weight of the fiber, and the thickness will naturally increase. Generally speaking, 60D and above are autumn and winter socks.
When wearing socks in winter, the socks should be kept dry first, because when the socks are damp, a large amount of moisture will squeeze out the air in the socks fibers, and air is an excellent heat insulator, which is more than 20% warmer than water. Therefore, once the socks get damp, they won’t keep warm.
Therefore, people who love to sweat on their feet should wear breathable and moisture-absorbing cotton or woolen socks, and should not wear nylon socks with poor moisture absorption and breathability. For people who are prone to dry skin on their feet, especially the elderly, it is very necessary to wear socks with poor moisture absorption. In comparison, wool socks have the best hygroscopicity, followed by cotton socks. Nylon socks are less hygroscopic than cotton socks, while polypropylene socks are almost non-hygroscopic.
How to distinguish the material of socks
When choosing socks, pay attention to distinguishing,Man-made fibers will feel slippery, while cotton is relatively rough. Open the socks and observe the surface. There are no brown spots or less, which is combed cotton. Generally, cotton socks will be added with acrylic in an appropriate amount to increase the elasticity of the socks. Socks with more cotton and less acrylic will have a soft hand feel, good moisture absorption, and will be more comfortable to wear.
