Why wear compression stockings?
Compression stockings, like compression garments in general, help prevent or treat certain conditions. First and foremost, compression stockings help improve blood circulation in the legs by putting pressure on the veins, facilitating blood flow back to the heart. Compression stockings are a good way to avoid the occasional feeling that your legs are heavy or swollen.
They exert gradual pressure starting at the ankle, where compression is highest. The pressure decreases moving up to the top of the leg.
