Compression Socks and Leg Compression – Which Compression Level Should You Choose and When?
Compression socks and other leg compression products are now used by more people than ever before. It’s no longer just about healthcare or rehabilitation, but also everyday life, work, travel, exercise, and preventive wellness. At the same time, many people feel unsure about which type of compression is best suited for their needs. What does mmHg actually mean? When is light compression enough, and when is stronger support needed?
In this guide, we go through how leg compression works, the different compression levels available, when they are used, and how to choose the right product for your needs. This article is designed as a complete knowledge guide for anyone who wants to understand the difference between various support socks, compression socks, tights, and compression sleeves.
What Is Leg Compression and Why Is It Used?
Leg compression means that even pressure is applied around the leg, strongest at the bottom and gradually decreasing upward. The purpose is to help blood circulate back toward the heart instead of pooling in the legs and feet.
When circulation is impaired, it can lead to:
-
Swollen legs and feet
-
Heaviness and fatigue
-
Varicose veins
-
Pain or tension
-
Increased risk of blood clots
Compression socks and other compression products help counteract this through graduated compression.
What Does mmHg Mean on Compression Socks?
mmHg is a medical pressure unit used to describe how strong the compression is in a support sock or compression product. The higher the mmHg value, the stronger the pressure the product applies around the leg.
Simply put, mmHg shows how much support the sock provides for your legs. It is a standardized unit of measurement used internationally in healthcare to measure and compare pressure levels, for example in compression products.
