What is a key function of compression hose?

Compression hose serve a key function of preventing swelling by supporting healthy blood flow in the legs. These types of garments are designed to exert graduated pressure on the legs, which helps propel blood upwards toward the heart. This compression improves venous return, reduces the risk of blood pooling in the veins, and can alleviate conditions such as venous insufficiency and deep vein thrombosis.

Using compression hose correctly aids in managing swelling and enhances circulation, making them beneficial for individuals who spend long periods standing or sitting, as well as those with specific medical conditions. The other options do not accurately capture the primary purpose of compression hose. While muscle strength and temperature regulation can be important for overall leg health, they are not the direct objectives achieved through the use of compression garments.
