Move Frequently

Sitting still for extended periods is one of the biggest risk factors for deep vein thrombosis. When flying, try to move around frequently to keep your blood flowing properly.

• Walk in the aisle: Once every hour or so, stand up and take a brief stroll. Walking, even for a short distance, helps improve circulation in your legs.
• Stretch your calf muscles: If you can’t leave your seat, extend your legs straight out and flex your ankles upward. Repeat this motion several times to engage your calf muscles, which act as a natural pump for your veins.

Making these small movements a regular part of your flight routine can significantly lower your risk of DVT.

Avoid Long Stretches in One Position

Remaining in the same position for hours at a time can restrict blood flow and increase the likelihood of a clot forming.

• Don’t cross your legs: While crossing your legs might feel comfortable initially, it can compress your veins and reduce circulation. Instead, keep both feet flat on the floor or elevate them if possible.
• Shift your position often: Make a conscious effort to adjust how you’re sitting every 20 to 30 minutes. Even small adjustments can help maintain better blood flow.

Stay Hydrated

Proper hydration is crucial for maintaining healthy blood circulation and reducing your risk of DVT while flying. Cabin air is notoriously dry, which can lead to dehydration—a contributing factor to poor blood flow.

• Drink plenty of water: Aim to sip water consistently throughout your flight. Bringing a refillable water bottle can make this easier.
• Avoid dehydrating beverages: Drinks like alcohol, coffee, and tea have diuretic effects, meaning they can dehydrate you further. Sleeping tablets should also be avoided, as they may make you less likely to move during the flight.

By prioritizing hydration, you’re helping your circulatory system function more efficiently.

Wear Compression Stockings

For those prone to vein-related issues or embarking on a particularly long flight, medical-grade compression stockings can be a game-changer.

• How they work: Compression stockings gently squeeze your legs, supporting your veins and encouraging better blood flow. This reduces the chance of blood pooling in your lower legs—a common precursor to clots.
• Choosing the right type: Consult with your doctor to ensure you select stockings with the appropriate compression level for your needs.

Compression stockings are discreet, comfortable, and can offer significant peace of mind for frequent travellers.

Opt for Loose-Fitting Clothing

What you wear on a flight can also impact your circulation. Tight clothing, especially around the waist or legs, can restrict blood flow and increase your risk of deep vein thrombosis.

• Wear loose, comfortable garments: Choose breathable, stretchy fabrics that won’t constrict your body.
• Minimize pressure points: Avoid belts or tight waistbands that can dig into your abdomen, as these can indirectly affect leg circulation.

Comfortable clothing not only enhances your travel experience but also plays a role in preventing circulation-related issues.

Final Thoughts

Flying doesn’t have to come with the worry of deep vein thrombosis if you take the right precautions. Moving regularly, staying hydrated, wearing loose clothing, and considering tools like compression stockings can make all the difference. Whether you’re a frequent flyer or someone planning a rare trip, incorporating these habits can help you travel more safely and comfortably.

By staying proactive and mindful of your body’s needs, you can enjoy your journey while keeping your health a top priority.
