In terms of material, it is "thin inside and soft outside, warm in the middle and windproof outside". Clothing itself does not generate heat, but keeps warm through the convection of cold air and hot air on the surface of the buffer. Wearing underwear too thick is not only uncomfortable, but also increases air convection in underwear and reduces warmth. Therefore, underwear should be made of light and soft cotton fabrics. The clothes in the middle layer don't touch the skin, which belongs to the warm layer and has strong hygroscopicity. Wool, cashmere and pure cotton are the most suitable materials. Sweaters, cashmere sweaters and cotton knitwear can be worn on it, and cashmere pants can be worn on it. The coat should be windproof and the fabric should be dense. It is not advisable to wear a wool coat. It should be reminded that the elderly are weak and can add a wool vest between the middle and outer layers.

However, it should be noted that thermal underwear is easy to generate static electricity and reduce skin moisture, so don't wear it beside it to avoid itching. The clothes in the middle should not be too tight and moderately loose, otherwise it will not only be bad for keeping warm, but also affect the temperature regulation function of the body and weaken the ability to keep out the cold. Excessive looseness and hypertrophy are easy to drill the wind, and cold air takes advantage of it, which is easy to cause heat dissipation and affect local warmth. Therefore, the neckline, cuffs, waist and ankles of the coat had better have a convergent design.

In part, "give consideration to both ends, with thick legs and no waist." Fingers and feet at both ends. Most of the body's heat is radiated from the head, so you must wear a hat when you go out. It is best to cover your forehead. If the wind is strong, you can choose a windproof leather hat. Cold in the neck may cause vasoconstriction and neck muscle spasm, so be sure to wear a scarf or turtle neck, especially not to expose the back of the neck. Cotton shoes have thick soles, pointed tips, low uppers and thin soles, which are not conducive to keeping feet warm. Legs are the most important thing to keep warm in winter. When the lower limbs are kept warm, the whole body will feel warm, which is why it is suggested that the elderly should dress "thin on the top and thick on the bottom". It is recommended to wear woolen pants to keep warm after deep winter, and Ms. Aimei should wear skirts as little as possible to reduce the time of showing her legs. If necessary, she can wear knee pads to keep her joints warm. So pay attention to the waist connection when dressing. The coat must cover the waist and wear less low-rise pants.
