Should You Wear Compression Socks on a Plane?

Should you wear compression socks on a plane? If you’ve ever experienced discomfort or swelling after a long flight, the answer could be yes.

What Are Compression Socks?

Compression socks are specialized hosiery designed to improve blood circulation in the legs. They work by applying gentle pressure to your leg and ankle, compressing the surface veins, arteries, and muscles.

This helps the blood vessels function better: the arteries can relax and allow more oxygen-rich blood to flow freely from your heart to your muscles, while the veins get a boost pushing blood back to your heart. They are often used in cases of edema, varicose veins, DVT, or other circulatory issues.

The Risks of Long-Haul Flights

Long-haul flights, typically those lasting over 4 hours, can pose several health risks due to prolonged immobility and cabin conditions. One such risk is Deep Vein Thrombosis (DVT), a serious condition characterized by the formation of blood clots in the deep veins of the legs. This can lead to leg pain or swelling, but in some cases, it can occur without any noticeable symptoms.

In worst-case scenarios, these blood clots can dislodge and travel to the lungs, causing a potentially fatal condition called pulmonary embolism. The risk of DVT is increased on long flights due to several factors:

  1. Prolonged Immobility: Sitting in one position for extended periods can cause blood to pool in the legs, increasing the risk of clot formation.
  2. Cabin Pressure and Low Humidity: The lower cabin pressure and low humidity in the airplane cabin can lead to dehydration, thickening the blood and making clot formation more likely.
  3. Restricted Legroom: The limited legroom in airplane seats can inhibit blood circulation, especially in economy class where space is often cramped.

The Benefits of Wearing Compression Socks on a Plane

Compression socks can play a significant role in mitigating the risks associated with long-haul flights:

  1. Reduced Risk of DVT: By applying gentle, graduated pressure to the legs, compression socks promote better blood circulation, helping to prevent the formation of blood clots.
  2. Reduced Swelling: The pressure applied by these socks helps reduce fluid buildup, minimizing the swelling (edema) that can occur during long flights.
  3. Increased Comfort: By improving circulation and reducing swelling, compression socks can make long-haul travel more comfortable, helping to alleviate the heavy or aching sensation in the legs often associated with long periods of immobility.
  4. Improved Oxygen Flow: Better circulation also means improved oxygen flow to your legs, helping to prevent fatigue and promote overall leg health.

Remember, while compression socks can significantly reduce the risks associated with long-haul flights, they should not replace movement and exercise during the flight. It’s still essential to get up, move around, and stretch regularly on long journeys.

Who Should Wear Compression Socks?

While anyone can benefit from wearing compression socks on a plane, they can be particularly helpful for certain groups of people:

  1. People with Venous Disorders: Individuals with venous disorders such as varicose veins or a history of DVT can benefit from the improved circulation provided by compression socks, as they are at a higher risk for blood clot formation.
  2. Pregnant Women: Pregnancy increases the risk of DVT due to changes in blood composition and pressure from the uterus on the pelvic veins. Compression socks can help prevent blood from pooling in the legs, reducing the risk of clot formation.
  3. The Elderly: Age increases the risk of blood clot formation, making the elderly more susceptible to DVT. Compression socks can help improve circulation in this population.
  4. People with Mobility Issues: For individuals who have difficulty moving around the cabin during the flight, compression socks can help improve blood flow in the lower limbs.
  5. Healthy, Active Individuals: Even healthy individuals can benefit from wearing compression socks on long-haul flights. They can reduce swelling and discomfort that comes from sitting for extended periods, and promote overall leg health.

How to Choose and Use Compression Socks

Choosing the right compression socks is important for their effectiveness. Here are a few key factors to consider:

  1. Size: Compression socks should be the right size for your feet and legs. Too loose, they won’t provide enough pressure; too tight, they may restrict blood flow. Use a sizing chart provided by the manufacturer for accuracy.
  2. Compression Level: Compression socks come in various levels of compression, measured in millimeters of mercury (mmHg). For travel, socks with mild to moderate compression (15-30 mmHg) are typically recommended.
  3. Material: They come in different materials, including cotton, nylon, or spandex, and the best one depends on personal preference and comfort.

For the best results, put on your compression socks before your flight and keep them on until after the flight. They should ideally be worn the entire time you’re seated. It’s also important to put them on correctly, starting from the toe and working up to the knee, making sure they aren’t wrinkled or twisted.

Other Measures to Reduce DVT Risk on a Plane

While wearing compression socks can help reduce the risk of DVT on a plane, other measures can also be taken to promote circulatory health during long flights:

  1. Regular Movement: Make sure to get up and move around the cabin every hour or two, if possible. If you’re not able to get up, try doing some simple leg and foot exercises in your seat. These can include ankle rolls, foot lifts, and knee lifts to promote blood circulation.
  2. Stay Hydrated: Drink plenty of water before and during your flight to prevent dehydration, which can contribute to blood thickening and clot formation. Avoid alcohol and caffeinated beverages, as they can lead to dehydration.
  3. Wear Loose Clothing: Tight clothing can restrict blood flow. Wearing loose, comfortable clothes can help promote better circulation during your flight.
  4. Leg Elevation: If possible, try to elevate your legs during the flight. This can be achieved by using the plane’s footrest, if available, or placing a small bag under your feet. This can help prevent blood from pooling in the lower extremities.
  5. Avoid Crossing Legs: Crossing your legs can restrict blood flow. Try to keep your legs uncrossed as much as possible during the flight.
  6. Aspirin: In some cases, doctors may recommend taking a low dose of aspirin before a flight to thin the blood and reduce the risk of clotting. However, this should only be done under medical advice, as aspirin can have side effects and may not be suitable for everyone.

Remember, it’s important to consult with your doctor before making significant changes to your routine, particularly if you have any existing health conditions or concerns.


Should you wear compression socks on a plane? Given the benefits, the answer leans heavily towards yes. Especially on long-haul flights, compression socks can contribute to a safer, more comfortable journey.
