Whether you’re catching a long flight, driving across the country, or sitting for hours on a bus or taxi, staying in one position for too long can slow blood flow in your legs and raise your risk of blood clots. The good news is that a few simple steps can significantly reduce your risk of developing a travel-related clot.
Understanding Blood Clots
A blood clot occurs when the blood thickens and forms a lump, often in a deep vein of the leg or pelvis. When this happens, it can block normal circulation. If a clot breaks loose and travels to the lungs, it can cause a pulmonary embolism (PE), a life-threatening emergency that requires immediate medical attention.
Keep Your Body Moving
Movement is your best defence against DVT. Sitting still for long periods causes blood to pool in your legs, increasing the risk of clots. Try to move or stretch your legs at least once every hour during long trips. Even small movements, like tapping your feet or tightening your calf muscles, can help keep your blood flowing and reduce your risk.
Stay Hydrated and Avoid Excessive Alcohol or Caffeine
Dehydration thickens your blood and increases the risk of clots, and it’s easy to forget to drink enough water when travelling, especially on long flights or car rides. Sip water regularly throughout your journey, and choose electrolyte drinks if you’re in hot conditions. Try to limit alcohol and caffeine, as both can dehydrate you and slow circulation. A simple tip is to keep a reusable water bottle with you and take small sips often, rather than waiting until you feel thirsty.
Wear Loose Clothing and Consider Compression Socks
Tight clothing, especially around the waist or thighs, can restrict blood flow and increase the risk of blood clots, so choose loose, comfortable outfits for long trips. If you’re at higher risk of DVT, compression socks can help by improving circulation and reducing swelling. They’re especially helpful for people over 40, pregnant women, anyone with a history of blood clots, and those who are overweight, who smoke, or use hormone-based medication.
Know Your Risk Factors and Talk to Your Doctor
Anyone can develop a blood clot, but some people are at higher risk, especially during long trips. Your risk increases if you’ve had blood clots before, recently had surgery or a leg injury, have a family history of clotting disorders, take birth control or hormone replacement therapy, have cancer or heart disease, or are pregnant or have recently given birth.
If you fall into any of these groups, speak to your doctor before travelling long distances; they may recommend extra precautions such as medication or compression therapy. If you notice symptoms of a blood clot while travelling, seek medical help immediately.
Bonus Tips for Safer Travel
- Avoid sleeping pills or anything that causes long periods of immobility.
- Stretch before and after your journey.
- Eat light, balanced meals to avoid sluggish circulation.
- When flying, choose an aisle seat for easier movement.
- Elevate your legs slightly when possible.
Blood clots can turn a dream trip into a medical emergency, but they’re largely preventable. Moving often, staying hydrated, wearing comfortable clothing, and understanding your personal risk factors can greatly reduce your chances of developing DVT while travelling.
