Traveler's Thrombosis: How Compression Stockings Support Your Circulation

During long journeys, many people experience heavy legs, swollen ankles, or tired calves. Less well-known is that prolonged sitting also affects blood circulation. Especially during long flights, car journeys, or train trips, blood flow in the legs can slow down. That's why you increasingly hear the term traveler's thrombosis.

At Herzog Medical, we regularly receive questions about compression socks during travel and flying. How exactly does compression work, and why do so many people choose it during long journeys?

What is traveler's thrombosis?

Traveler's thrombosis is a collective term for thrombosis symptoms that can occur during or after prolonged sitting, for example, during a long flight or car journey.

When you move little for a long time, the muscle pump in your calves works less actively. This causes blood to flow back more slowly from the legs towards the heart.

Especially for journeys longer than four hours, the strain on the circulatory system increases.

Why do legs suffer during travel?

During travel, a combination of factors often occurs:

prolonged sitting
little movement
limited legroom
warmer conditions
fluid retention

This can lead to symptoms such as:

heavy legs
swollen ankles
tired calves
a tense feeling in the legs

During air travel, the cabin air pressure also plays a role.

How do compression socks support blood circulation?

Compression socks apply pressure to the leg, with the highest pressure at the ankle and gradually decreasing towards the calf. This is also known as a controlled pressure gradient.

This way, compression socks support blood circulation during prolonged sitting or standing.

Why Herzog compression socks are suitable for travel

Not every compression sock offers the same support. At Herzog Medical, we work with medical compression technology that has been translated for active and daily use.

Herzog compression socks are produced on the same machines as therapeutic elastic stockings and offer precisely controlled compression pressure. Additionally, Herzog compression socks are medically certified according to MDR guidelines.

While many brands work with standard sizes such as S, M, and L, Herzog uses an extensive sizing system. This allows the compression to fit the leg more accurately, which is important for long-term wear while traveling.

Drinking enough helps keep your body balanced while traveling.

Even during car journeys, it helps to stop regularly.
