Is constant temperature underwear harmful?

Nowadays, there are many styles of underwear, and people have a wider range of choices. Not to mention constant temperature underwear, this type of underwear will keep people warm and usually will not cause any harm to the body, so there is no need to worry too much. However, for some people who like to wear tights, they should try to avoid it, especially for girls.

The first taboo: thermal underwear is too tight

Although close-fitting thermal underwear can show your body curves, it will also expose the traces of the thermal underwear. Thermal underwear that is too tight will leave ugly marks on the original body curves.

Expert advice: Thermal underwear that is too tight will not only leave unsightly marks when you wear it, but experts also recommend that women should not wear thermal underwear that is too tight, as it poses a great threat to women's physiology.

The second taboo: love synthetic thermal underwear

Wearing synthetic thermal underwear for a long time will make the body feel stuffy. If the synthetic thermal underwear is not breathable, redness, swelling and congestion are inevitable.

Expert advice: Synthetic fiber thermal underwear is loved by women for its good elasticity and sexy colors, but sometimes it inevitably puts a lot of pressure on delicate skin. If you need to wear it when going out or going to work, you should change into cotton, loose thermal underwear in time when you get home so that the local area can get enough rest.

The third taboo: carefully choose dark thermal underwear

Some dark thermal underwear will have a pungent odor, this is because many substandard underwear contain degradable aromatic amine dyes. If there is a pungent smell, it may be that the formaldehyde content is high. When purchasing thermal underwear, you should carefully choose dark-colored thermal underwear. Degradable aromatic amine dyes are dyes banned in China. When clothing dyed with these banned dyes comes into contact with human skin for a long time, they will mix and react with components released during the human body's metabolism to form substances that are harmful to health. And from a physiological point of view, dark-colored thermal underwear can also mask the signs of disease and delay the onset of the disease.

Keeping warm is related to the thickness of clothes. If you wear thick clothes, you will definitely be warm, but if you wear thin clothes, you will feel cold. Therefore, there is almost no thermal underwear that is both thin and warm. If you want to dress warmly, you can look at the warmth retention rate of the underwear when choosing. The country has promulgated standards for thermal underwear, requiring that the warmth retention rate of thermal underwear should be higher than 30%. The higher the value, the warmer it is, but the clothes may also be correspondingly thicker.
