Look after yourself when flying long distances

Although the summer months are often spent travelling to destinations in Europe, many people also spend their summer holidays on longer trips, for example, to the USA and Asia. Travelling to destinations outside of Europe involves a long flight that can be stressful, both mentally and physically.

SOS International’s doctors have compiled their best advice for air travellers:

General advice for long flights:

1. Be as active as possible. It is recommended that you stand up and walk around a little every hour. Move your feet often while sitting down.
2. Drink a lot - but lay off coffee and alcohol
3. Exercise caution with sleeping medicine
4. Compression stockings can help to prevent blood clots on flights lasting more than four hours

Do you have health problems?

If you have health problems, you should consult a doctor before going on long flights. Some conditions can actually be made worse by the flight.

Semera Asghar, Chief Medical Officer at SOS International and Anaesthesiologist at Rigshospitalet in Copenhagen, explains that long flights may increase the risk of blood clots, particularly in the legs but also in other places. And the risk is increased if you are already in a high-risk category.

In other words: Patients with cardiovascular diseases, cancer and impaired immune systems must be extra careful and should take their own precautions before a long flight. Patients with lung diseases should also take their own precautions before a long flight.

“These conditions are generally worsened, as the oxygen saturation in the air inside aircraft cabins is not as high as on land, so it can become difficult to breathe for people who have pre-existing lung conditions. There is also a difference in the air pressure inside aircraft cabins and this, combined with the fact that you are sitting still most of the time, may cause dehydration and your blood to become thicker and circulate around the body at a decreased rate. The likelihood of getting blood clots is therefore increased,” says Semera Asghar.

Medical pre-assessment

If you are chronically ill, under evaluation or your illness is unstable, SOS recommends that you undergo a medical pre-assessment. A medical pre-assessment can clarify how the patient’s trip will be covered by insurance and how a flight can affect the patient’s health.

If you do not have any known health problems, there are still a number of things you can do to ease the discomfort of long hours inside the aircraft cabin.
