Which of the following best describes the function of compression socks?

The function of compression socks is primarily to support circulatory health. These specialized socks apply gentle pressure to the legs and feet, which helps to improve blood circulation and reduce the risk of conditions such as deep vein thrombosis, varicose veins, and swelling. Compression socks work by helping the veins return blood more efficiently to the heart, which can alleviate discomfort and promote recovery after physical activity.

In contrast, the other options do not accurately reflect the primary purpose of compression socks. While they may provide some warmth due to their material, that is not their main function, which distinguishes them from regular socks designed for warmth. Cooling extremities is not a characteristic of compression socks; rather, they can increase the temperature of the leg due to the pressure applied. Lastly, they do not influence sweat production; their role centers around supporting vascular and circulatory function.
