How to keep warm with a quilt in winter is correct?

Quilts can be covered in order to warm you to sleep, and blankets and duvets can warm you.

When the temperature is getting lower and lower, many people will put towels, blankets and other bedding on the quilt to keep warm and sleep. In order not to cover your body with too many layers, which makes it difficult to turn over, and to keep your body warm and have a good sleep, the key is to cover it correctly!

Yoko Nanbu, president of TRAUBE, a Japanese women's nursing consultancy, said that when the weather is cold, the basic equipment for many people to sleep is a quilt and a blanket. If the quilt is a heavy quilt or a synthetic fiber quilt, the layer that will directly contact the skin should be a blanket, and then cover the blanket with a quilt. However, if you cover the duvet and blanket, the order is reversed. Cover the duvet first, then the blanket, so that the heat preservation effect is good.

The duvet is light and warm, and the blanket can lock in the heat.

Thin and warm duvets have become the mainstream in recent years. Xing Zi Nakano, a researcher at the Sleeping Environment Laboratory of Maruya Research Center, said that when the duvet directly touches the body, it can make the duvet expand through the body temperature, making people feel warm, while the blanket has the function of locking hot air and preventing heat energy from escaping. If a blanket is put between the body and the duvet, the down can't become fluffy enough, the warmth of the duvet will be blocked by the blanket, and the heat energy can't be directly transmitted to the body.

Most people think that the blanket feels comfortable, so they will choose to cover it on the innermost layer, but in order to get good insulation effect, it is still recommended to cover it. If you feel that the duvet will be very cold if it touches the body directly, you can also put a duvet on the outside of the duvet. Warm and comfortable temperature can make people fall into deep sleep, so women who are weak and afraid of cold or elderly people who often find it difficult to warm their bodies must try it.

Man-made fibers are difficult to dissipate heat and have poor hygroscopicity, so direct contact with the body should be avoided.

The common materials of blankets are acrylic or polyester, both of which belong to man-made fibers, and it is difficult to dissipate heat. At the same time, because the blanket has no function of adjusting humidity, moisture may be trapped inside. If it is a cotton blanket, it is also recommended to cover the outermost layer like a man-made fiber quilt. However, if it is a natural blanket such as cashmere blanket, wool blanket and velvet blanket, it can be placed under the duvet and directly contact with the skin because of its characteristics of heat storage and temperature evaporation.

Xing Zi Nakano, a researcher, warned that hot air could easily slip away from the bottom of the body. Sleeping with a blanket on the sheet can prevent the loss of hot air and improve the warmth retention effect. However, you need to pay attention to the material of the blanket. Because the artificial fiber blanket has poor moisture absorption effect, it may keep the water in the bed, but it will take away the body temperature and cause sultry discomfort. Transmission under the body should be avoided.
