Flight Socks: Do They Really Work?

If you’ve never had a pair of flight socks before or don’t know too much about them, you may be a bit sceptical over if they actually really work. Pulling on and off these tight socks may just seem like a hassle, but they actually have a few different purposes to keep you comfortable and healthy while you are in the air.

Let’s take a look at what they can do.

Decrease risk of Deep Vein Thrombosis and blood clots

If you haven’t heard of Deep Vein Thrombosis (DVT) before, it’s a type of blood clot that you can get in your lower legs or feet. It often occurs when sitting in one place too long, which is exactly what happens to a lot of people on long haul flights. The lack of blood flow and circulation causes the blood to pool in your lower limbs, causing swelling and leg fatigue, or even worse, a clot that can travel up to your heart and be fatal.

People at risk of developing DVT include:

  • Pregnant ladies
  • Diabetics
  • Those on oestrogen supplements or birth control
  • Those with hereditary DVT or blood-clotting disorders
  • Overweight people

When you wear flight socks, the tight material squeezes your leg tissues and veins to encourage circulation and get the blood pumping back up your body.

As well as avoiding DVT and blood clots, the socks can make your legs feel less tired after your long journey.

Reduce swelling

People that are at risk of oedema or swelling are usually advised by their doctors to wear compression socks on long haul flights.

This is because wearing socks squeezes the leg tissue and in turn improves the flow of lymph fluid that surrounds cells. When there is a normal flow of lymph fluid, swelling is reduced or avoided with the right amount of compression. A person can arrive at their destination without puffy feet and ankles, otherwise they may be unable to wear their shoes properly or even walk comfortably.

Alleviate symptoms of other ailments

Flight socks are not only for people at risk of DVT, blood clots or swelling. They are often worn by people with the following conditions to help with comfort during a flight:

  • Varicose veins
  • Leg ulcers
  • Circulatory problems

Can I wear any pair of flight socks?

Actually, there are different grades of compression socks, which can be matched to your level of risk of DVT or swelling. Those who are at a higher risk should look for a compression grade of 20-30 mmHg, while most other people will be fine with 15-20mmHg. Making sure you have the right grade for your needs will be key to staying healthy on your next flight.
