10 Podiatrist Tips to Prevent Leg Swelling During Flights
1. Wear Compression Socks
Graduated compression stockings help improve circulation by gently assisting blood back towards the heart.
Compression stockings can:
- reduce ankle swelling
- decrease leg fatigue
- improve circulation
- reduce the risk of travel-related DVT in appropriate patients.
Your podiatrist can recommend the correct compression level for your needs.
2. Keep Moving Every Hour
One of the best things you can do is simply move.
If safe:
- walk up and down the aisle
- stretch your calves
- stand for several minutes every hour.
Movement activates your calf muscles—the body’s natural “second heart.”
3. Perform Simple Exercises While Sitting
Even if you can’t leave your seat, keep your circulation moving.
Try:
- ankle pumps
- ankle circles
- heel raises
- toe raises
- pointing and flexing your feet
- gently tightening your calf muscles.
Repeat these every 30–60 minutes.
4. Stay Well Hydrated
Aircraft cabins are extremely dry.
Drink water regularly throughout your journey and limit excessive alcohol and caffeine, which can contribute to dehydration.
Good hydration supports healthy circulation.
5. Avoid Crossing Your Legs
Crossing your legs places additional pressure on blood vessels and can further slow circulation.
Keep both feet flat on the floor whenever possible.
6. Choose Comfortable Footwear
Your feet naturally expand during long flights.
Avoid:
- tight shoes
- narrow footwear
- restrictive socks.
Supportive walking shoes with adequate room are often the most comfortable option.
7. Reduce Salt Before Travelling
High sodium intake encourages fluid retention.
For a day or two before travelling, try limiting:
- processed foods
- takeaway meals
- salty snacks
- cured meats.
8. Wear Loose Clothing
Tight jeans, restrictive waistbands and tight socks can impair circulation.
Loose, comfortable clothing allows better blood flow.
9. Elevate Your Legs Whenever Possible
Before boarding and after landing, spend 15–20 minutes with your legs elevated above heart level if possible.
This encourages fluid to return towards the heart and may reduce swelling.
10. Consider Compression Therapy Before or After Travel
For people who frequently experience swollen legs, intermittent pneumatic compression therapy may help improve circulation, reduce fluid build-up and assist lymphatic drainage.
At The Foot Force Podiatry, we provide pneumatic compression therapy for suitable patients experiencing:
- chronic leg swelling
- venous insufficiency
- lymphoedema
- prolonged standing at work
- travel-related swelling
- tired, heavy legs.
A clinical assessment is performed first to ensure treatment is appropriate and safe.
