How to dress if you want to keep warm in cold weather?

After the severe cold, the temperature in all parts of the country began to drop gradually. The biting cold forced people to add clothes and trousers to keep warm and catch a cold. However, people have some misunderstandings about the concept of adding clothes to keep warm, which leads to the colder they wear. So if they want to keep warm in cold weather, how should they dress?

In fact, it is better to wear appropriate clothes and wrap yourself up from the inside out to keep warm.

Let's talk about the principle of dressing to keep warm. Clothing can keep warm by reducing heat conduction. In other words, clothes buffer the convection of cold air and hot air on the body surface, thus saving heat.

So in order to keep warm, we must minimize heat conduction. As we all know, air has the worst thermal conductivity among available materials. From this point of view, when we wear multi-layer clothes, we should pay attention to keeping the air between the interlayers and reducing heat conduction. This also explains the phenomenon that it is obviously not warm when wrapped in many pieces-there is less air between clothes, but the heat conduction is accelerated.

So, what should I wear in the next few days? Here is a recipe for everyone-thin and soft inside, warm in the middle and windproof outside. Wear these three layers of clothes to protect the neck, head, hands, feet and knees that are particularly afraid of cold. Remember to wear a hat and scarf when you go out, and the ice and snow under the cold wave can survive.

First floor: underwear

In the choice of the first layer of clothes, some people like thick velvet underwear and think it is warmer. In fact, too thick underwear is not only uncomfortable, but also increases air convection in underwear and reduces warmth.

In addition, winter is dry and people's skin is sensitive. Underwear is close-fitting, so soft and non-irritating materials should be preferred.

Therefore, I suggest you choose light and soft cotton underwear to absorb sweat and keep warm.

Second floor: sweaters

Generally speaking, the middle layer clothes belong to the warm layer and do not directly contact the human skin. In the selection of materials, wool, cashmere and pure cotton with strong hygroscopicity are the most suitable materials.

In terms of clothing style, the mid-range clothes should be moderately loose, and the neckline and cuffs should have a convergent design. Too tight clothes are not conducive to keeping warm, but also affect the body's temperature regulation function; Too loose and fat clothes are easy to produce pneumatic drills, and cold air takes advantage of it to cause heat dissipation and affect warmth.

It is recommended that you wear moderately loose sweaters, cashmere sweaters, cotton sweaters and two-layer sweaters in winter. If the elderly are weak, you can also add a sweater vest.

The third floor: coat

The warm-keeping effect of coat is mainly influenced by fabric and filler. It is easy to understand-the density of fabric affects the wind resistance; The type and thickness of filler affect the thermal insulation performance.

Here we compare the common down jacket, thick cotton-padded jacket, leather coat and tweed coat.

Generally speaking, the fabrics of down jackets, thick cotton-padded jackets and leather jackets are relatively dense, so the wind resistance is relatively strong. However, the filling thickness of leather coat is not enough, and the thermal insulation performance is poor.

Fillers such as down and cotton in down jackets and thick cotton coats are fluffy and breathable, which can absorb a lot of air to form a protective layer to store heat, so they have better thermal insulation performance.

Dotweed coat is generally made of natural fibers such as wool and synthetic fibers such as polyester and viscose, with a thin filling thickness and relatively poor thermal insulation performance.

Therefore, when choosing a coat, it is recommended that you choose a down jacket and a thick cotton-padded jacket with strong wind and warmth.

The above is to introduce the most suitable way and principle of dressing in cold weather. Sometimes it is not a good thing to wrap too thick, so after the above guidance, I hope everyone can know what kind of clothes to wear, which is comfortable and warm, so that they will not worry about what clothes to wear because they are afraid of the cold.
