Beijing has been sunny in recent days, but the cold air is still coming. What?! Are you still wrapping yourself up in three layers of clothes in winter? Take them off quickly. This article will tell you how down jackets keep you warm and the best way to keep warm in winter!

Wear a thin down jacket to keep warm

In daily life, we can feel that the down jackets we wear are thick but light, which is thanks to the fluffy down layer.

Down jackets do not generate heat themselves, they keep warm mainly by preventing the body from losing heat. The warmth retention of down jackets mainly comes from their filling material - down. They can capture air and form a static "air wall" to slow down the loss of body heat. It can be said that the warmth retention effect of down jackets depends largely on the thickness of the air layer inside them.

Due to the unique spherical structure of down and the thousands of down branches on each down, these branches combine with the air to form a body, which increases the thermal conductivity, can effectively prevent heat conduction, and has a better warming effect.

But there is a common misunderstanding : the more and thicker the clothes you wear, the warmer you will be .

In fact, it is not true. Wearing thinner clothes inside a down jacket will make you warmer . This is because wearing too thick clothes inside a down jacket will compress the down layer and reduce the amount of air inside . When the number of layers of clothing exceeds a certain value, the amount of air between the layers will decrease as the number of layers of clothing increases, reducing the insulation effect.

Therefore, in winter we can choose not to wear too many layers, nor too tight, but a slightly looser layer, creating an extra air layer in the inner layer to achieve better warmth!

Learn the "sandwich" dressing method! In winter, the more you wear, the warmer you will be. Learn the sandwich dressing method and wear only three pieces to keep warm. Even if the temperature is 10 or 20 degrees, you won't feel cold. This is the magic of the "sandwich" dressing method!

When putting on clothes we can divide them into three layers , like a sandwich:

The innermost layer is closest to our body and is mainly responsible for ventilation ;

Then there is the middle layer, which is mainly used for warmth and beauty;

Finally, the outer layer is responsible for windproof and warmth . Down jacket is used as the outer layer, and the inner layer is thinner to better adapt to this dressing method.

1. Inner layer (close to the body)

Function: Moisture wicking, keeping the body dry.

Recommendation: Choose pure cotton or moisture-wicking sports fabrics to prevent moisture generated by human metabolism from accumulating in the clothing, affecting the fluffiness of the outer layer and reducing thermal insulation performance.

2. Middle layer (warmth layer)

Function: Provides warmth while remaining breathable.

Recommendation: Use wool, down or fleece materials to create an air layer and choose a slightly looser style to facilitate movement.

3. Outer layer (protective layer)

Function: Windproof and waterproof, protecting the inner layer from external influences.

Recommendation: Choose windproof and waterproof jackets, such as down jackets, cotton jackets, cashmere coats, eco-friendly fur, jackets, etc., and consider breathability.

However, in humid and cold areas, such as the middle and lower reaches of the Yangtze River, the feeling of cold will be more obvious due to the high humidity. The thickness, type and number of clothes should be judged according to actual physical conditions.
