Do You Need Compression Socks For Flying? Yes, compression socks can be beneficial for some travelers during flights, particularly those at higher risk of blood clots, but they aren’t a necessity for everyone. Flyermedia.net delves into the science and expert opinions surrounding compression socks and air travel, offering a clear understanding of their potential benefits and limitations in reducing the risk of Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE). Discover whether these socks are right for you and how to maximize your in-flight well-being with insights from leading medical professionals and aviation experts.
1. Understanding the Risk: Blood Clots and Flying
Flying, especially long-haul flights, has been linked to an increased risk of venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE). But what exactly makes flying a risk factor, and how significant is that risk?
1.1 What is Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE)?
Deep vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, usually in the leg. Pulmonary embolism (PE) occurs when a blood clot travels to the lungs and blocks a blood vessel. Both conditions can be serious and even life-threatening. According to the American Heart Association’s most recent statistics, an estimated 666,000 people in the U.S. were hospitalized with DVT in 2020, and an additional 432,000 were hospitalized for PE. In 2021, VTE was mentioned as a cause of nearly 81,000 deaths.
1.2 How Does Flying Increase the Risk of Blood Clots?
A long-haul flight makes VTE from 1.5 to four times more likely. There are several factors contributing to this increased risk:
- Immobility: Sitting in a cramped seat for extended periods restricts movement, reducing blood flow in the legs.
- Dehydration: The dry cabin air can lead to dehydration, which thickens the blood and makes it more prone to clotting.
- Lower Air Pressure: The reduced air pressure in the cabin can also affect blood circulation.
Eri Fukaya, a vascular medicine specialist at Stanford University in California, emphasizes that flying can create “a perfect storm for a clot.”
1.3 What is the Actual Risk of Developing Blood Clots from Flying?
While the risk is increased, it’s important to understand that the absolute risk of developing severe blood clots specifically from flying remains relatively low. A 2007 research review in the Journal of Internal Medicine estimated there are 4.8 cases of severe pulmonary embolism per million flights longer than 12 hours. The risk of DVT within four weeks of a flight of at least four hours was 1 in 4,600 flights.
Joshua Beckman, director of vascular medicine at UT Southwestern Medical Center in Dallas, notes that the low risk makes studying the effectiveness of preventative measures challenging.
2. Compression Socks: What Are They and How Do They Work?
Compression socks are designed to improve blood circulation in the legs. They apply pressure at the ankles, with the pressure gradually decreasing further up the leg. But how exactly do they work, and what are the different types available?
2.1 How Do Compression Socks Improve Blood Circulation?
Compression socks work by:
- Squeezing the ankles: This helps to narrow the veins, increasing blood flow velocity.
- Supporting vein walls: The pressure helps to prevent blood from pooling in the legs.
- Forcing blood back to the heart: By improving venous return, compression socks reduce the risk of blood clots.
2.2 Types of Compression Socks
There are different types of compression socks available, each with varying levels of compression:
| Type of Sock | Compression Level (mmHg) | Common Uses |
|---|---|---|
| Mild Compression | 8-15 mmHg | Provides slight support, relieves minor leg fatigue and swelling; often used for everyday wear. |
| Moderate Compression | 15-20 mmHg | Used for travel, mild varicose veins, and during pregnancy to improve blood flow and reduce swelling. |
| Firm Compression | 20-30 mmHg | Recommended for moderate to severe varicose veins, lymphedema, and post-surgical use; consult a healthcare provider before use. |
| Medical-Grade Compression | 30-40 mmHg and higher | Used for severe venous conditions, deep vein thrombosis (DVT), and severe lymphedema; requires a prescription and professional fitting due to the high level of compression provided. |
2.3 How to Choose the Right Compression Socks
Choosing the right compression socks depends on individual needs and risk factors. Factors to consider include:
- Compression level: Start with a lower compression level if you’re new to compression socks.
- Length: Knee-high socks are generally recommended for flying.
- Material: Choose a breathable material like cotton or microfiber.
- Fit: Ensure the socks fit properly and are not too tight or too loose.
Fukaya suggests starting out with a medium sock and switching to “mild” or “spicy” depending on how it feels.
3. The Evidence: Do Compression Socks Really Help Prevent Blood Clots During Flights?
The effectiveness of compression socks in preventing blood clots during flights has been the subject of several studies. What does the evidence say?
3.1 Cochrane Review Findings
A review of research in the Cochrane Database of Systematic Reviews that was updated in 2021, looked at data from 2,918 people in 12 randomized clinical trials. It found high-certainty evidence that wearing compression stockings reduced the risk of symptomless DVT when traveling on a flight of more than four hours. However, it could not offer conclusions about any effect on the odds of death, pulmonary embolism, and symptomatic DVT because no trial participant had those problems.
3.2 American Society of Hematology Guidelines
American Society of Hematology guidelines do not recommend compression socks for low-risk travelers on short flights and recommend socks on longer flights only for people at high risk of blood clots.
3.3 Studies in High-Risk Groups
A study published in 2022 in the American Journal of Obstetrics and Gynecology: Maternal-Fetal Medicine looked at VTE in a high-risk group: women who were pregnant or had just given birth. Women who flew did have more risk compared with those who did not fly. But the difference was “very tiny,” he said – 0.07% versus 0.05%, respectively.
3.4 Expert Opinions
Beckman emphasizes that the risk of developing severe blood clots specifically from flying remains so low that it’s almost impossible to say whether compression socks make any difference in preventing blood clots among flyers.
4. Who Should Wear Compression Socks for Flying?
While compression socks may not be necessary for everyone, certain individuals may benefit from wearing them during flights.
4.1 Risk Factors for VTE
People with the following risk factors are at higher risk of VTE and may consider wearing compression socks:
- Older age
- Smoking
- Obesity
- Family history of severe clots
- Previous history of blood clots
- Recent cancer treatment
- Estrogen use
- Pregnancy or recent childbirth
Fukaya likens such risks to water in a bucket. Someone whose bucket is nearly filled by those factors will be at higher risk than someone with an empty bucket.
4.2 When to Consult a Doctor
If you have any of the above risk factors, it’s always best to consult with your doctor before flying to discuss whether compression socks are right for you.
5. Other Ways to Reduce the Risk of Blood Clots During Flights
In addition to compression socks, there are several other measures you can take to reduce your risk of blood clots during flights.
5.1 Lifestyle Adjustments
- Stay Hydrated: Drink plenty of water before, during, and after your flight.
- Avoid Alcohol and Caffeine: These can contribute to dehydration.
- Move Around: Get up and walk around the cabin every couple of hours.
- Exercise Your Legs: While seated, flex your calf muscles and roll your ankles around in big circles, both directions. Then take off your shoes and wiggle your toes.
5.2 Medical Precautions
- Anticoagulants: In some cases, your doctor may recommend taking an anticoagulant medication before flying.
- Medical Assessment: If you have a history of blood clots or other risk factors, your doctor may recommend a medical assessment before flying.
Beckman advises travelers worried about blood clots to “get up and walk every couple of hours. Drink lots of water.”
6. The Comfort Factor: Beyond Blood Clot Prevention
Even if you’re not at high risk of blood clots, compression socks can offer other benefits during flights.
6.1 Reducing Swelling and Discomfort
Compression socks can help to reduce swelling and discomfort in the legs and feet, which can be common during long flights.
6.2 Improving Circulation
By improving blood circulation, compression socks can help to reduce fatigue and improve overall comfort during flights.
6.3 Personal Preference
Ultimately, whether or not to wear compression socks during flights is a matter of personal preference. If you find them comfortable and helpful, there’s no reason not to wear them.
Fukaya wears them almost every day and says that “my legs feel a lot better wearing them.”
7. Debunking Myths About Compression Socks
There are several misconceptions about compression socks. Let’s set the record straight.
7.1 Myth: Compression Socks Are Only for Old People
While older adults are at higher risk of blood clots, compression socks can benefit people of all ages who are at risk or who simply want to improve their comfort during flights.
7.2 Myth: Compression Socks Are Uncomfortable and Ugly
Modern compression socks come in a variety of styles and materials, and many are designed to be comfortable and stylish.
7.3 Myth: Compression Socks Are a Substitute for Medical Treatment
Compression socks are not a substitute for medical treatment. If you have a history of blood clots or other medical conditions, it’s important to consult with your doctor.
