How Do Compression Socks Work?

Compression socks and stockings have become well-known for helping to manage circulation-related conditions. But how do compression socks work, and who can benefit from using them? Whether prescribed by a healthcare provider or worn during long flights, these medical-grade garments may support better blood flow and potentially help with a range of issues, from swelling to varicose veins.

Let’s break down how compression therapy works and explore the medical benefits of compression socks.

How does compression therapy work?

Compression therapy involves applying external pressure to the lower limbs using specially designed apparel like stockings or socks to counteract low internal venous pressure. This is believed to help improve the function of veins and reduce blood stagnation. Over time, it supports better circulation, eases discomfort and minimises swelling.

The effects of wearing compression garments are most noticeable when they’re worn consistently, especially during activity or long periods of sitting or standing. For best results, they should be put on in the morning when swelling is typically at its lowest.

How compression socks improve circulation

Compression socks are made with elastic fibres that apply graduated pressure to the legs — strongest at the ankle and gradually decreasing as they move upward. This gentle pressure encourages blood to flow upward towards the heart, which helps to reduce the chance of blood pooling in the lower limbs.

So how do compression socks work to support circulation? By compressing the surface veins and surrounding tissues, they help reduce the diameter of blood vessels, which may allow vein valves to close more effectively, pushing blood upward rather than allowing it to pool.

Compression sock technology is specifically designed to help oxygen-rich blood reach muscles more efficiently and allow waste products like lactic acid to be cleared out faster.

Additional medical benefits of compression socks and stockings

Beyond circulation support, compression socks — or compression therapy in general — may be beneficial for people managing chronic or temporary conditions, as they can potentially:

• Reduce swelling — Compression socks for swelling may help reduce fluid build-up in the legs and ankles, commonly experienced in pregnancy, post-surgery or during long periods of inactivity.
• Support varicose vein management — So how do compression socks help with varicose veins? By compressing the surface veins and surrounding tissues, they help reduce the diameter of blood vessels, which may allow vein valves to close more effectively, pushing blood upward instead of pooling. This can help ease discomfort, reduce swelling and support healthier vein function over time.
• Promote healing — Compression stockings may assist recovery in cases of venous ulcers or post-surgical healing by supporting better circulation and oxygen delivery.
• Help prevent blood clots — Compression stockings or socks are particularly useful in hospital settings, during travel or for those prone to DVT.

The benefits of compression socks make them a go-to product for those managing chronic venous insufficiency or recovering from injuries.

Who should wear compression socks

Compression socks are commonly recommended for people with a variety of health needs and lifestyles:

• Individuals with varicose veins or poor circulation
• Pregnant women experiencing swelling
• Office workers or those who stand or sit for long hours
• Post-operative patients
• Athletes recovering from intense workouts
• People taking long flights
• Elderly individuals

However, always consult a healthcare professional to determine the right compression level, as medical-grade compression comes in different strengths depending on the condition being treated and might not be safe for everyone.

Compression stockings vs socks

Though the terms are sometimes used interchangeably, there are key differences between compression socks and stockings. Compression socks typically reach the knee and are ideal for daily wear, travel and mild swelling management. They’re a practical option for anyone needing ongoing support for circulation and leg comfort during routine activity.

Compression stockings can go higher — to the thigh or waist — and are often used for more intensive medical needs, such as post-surgical recovery or managing advanced venous insufficiency. If you're looking for compression stockings in Australia, look for certified options and check with your doctor to confirm the appropriate strength and length for your needs.
