Introduction: Although it is winter, girls wearing tights can be seen everywhere on the streets of Changsha. Tight tights make calves look slender, so they are the first choice for many women who love beauty. The original intention of many women to buy leggings is that wearing leggings can make their legs slim, so does leggings really have such a magical effect? Tights are fake varicose socks. The tights on the market now are actually fake varicose socks. Varicose socks have been around for more than 20 years, which are actually medical elastic socks. Compared with leg tights, medical elastic socks are designed as "semi-foot-wrapped" according to the pressure gradient, and are "tightened up", which is measured and selected by professional medical personnel. Elastic socks are mainly used to assist in the treatment of varicose veins and deep vein thrombosis in clinic. For patients with venous insufficiency, doctors will also recommend avoiding wearing tights, so there is no comparability between the two. Normal people wearing tights for a long time will also oppress the capillaries of the calf, which is not conducive to the blood circulation of the leg, increase abdominal pressure and increase the burden on the heart and lungs, thus causing symptoms of multiple organs congestion in the digestive system. Leg tights can thin legs, is it true? Leg tights will squeeze leg muscles and fat space. After wearing it, you will feel your legs tight, but you won't burn fat. The reason why the legs become "thin" is because the leg tights temporarily squeeze out venous blood and the legs appear thin; After taking off the socks, venous blood returns and the legs return to their original state. Therefore, tights do not have the function of stovepipe, which is obviously a marketing tool for businesses. In addition, it should be noted that if you wear tights for a long time, your leg muscles will become slack. Everyone has a love of beauty. However, female friends should not wear it for too long. They can wear it when shopping or walking for a long distance, and when they get home, especially when they sleep, they should take it off. Leg tights should also be breathable, and poor permeability may cause local skin allergies. Pregnant women, as well as patients with cardiovascular disease and diabetes, should never wear them.
