Flying is the safest form of transportation, and the vast majority of air travellers reach their destinations comfortably and with no health issues whatsoever, but air travel does present a unique environment that can cause certain stresses to passengers. Check out these tips and stay healthy and comfortable on your flight.
Quick tips for healthy air travel
Get some rest before you fly – in the days before your departure, be sure to get plenty of sleep. No matter how comfy your seat is, it can be hard to get to sleep on airplanes and your own bed will provide a more restful sleep.
Drink plenty of water and juice – the airplane environment is dry. Humidity levels on the plane can drop below 10 per cent and cause ailments such as dry skin or dehydration. Drink plenty of fluids, but avoid alcohol and caffeine, which just dry you out further.
Move around the cabin – maintaining good blood circulation during air travel can help avoid discomfort and rare, yet potentially serious, diseases such as Deep Vein Thrombosis (DVT). This circulatory disorder can be life-threatening, so it’s worth learning about. Getting up and walking when the fasten seatbelts sign goes off helps prevent DVT.
Prevent motion sickness – if you’re prone to car sickness, consider medication for your flight and don’t do a lot of reading. Consult your doctor prior to taking anything new. This goes for over-the-counter meds, too. Luckily, there are a lot of options that really do work for air travellers, such as travel sickness wrist bands.
Air travel health concerns – Jet Lag
What is jet lag?
Jet lag is a very common health issue resulting from long-haul airline flights. The primary symptoms are dizziness, fatigue, irritability, lack of concentration, and the inability to perform simple, everyday functions.
What causes jet lag?
Flying across multiple time zones is the main culprit. Jet lag seems to be worse on east-bound air travel than on west-bound. However, even north to south flights can cause pretty tough jet lag due to the unique stresses of the airplane environment.
How do you combat jet lag?
To reduce jet lag, and make the plane ride smoother, drink plenty of water, avoid alcohol and caffeine, try to exercise at least once every two hours and avoid heavy meals immediately before travel and while you're in the air.
Air travel health concerns – Deep Vein Thrombosis (DVT)
What is DVT?
DVT is arguably the most serious health risk to air travel, although it remains rare. DVT occurs when the blood changes from a liquid to a solid state and produces a clot. The most common veins affected are those of the legs and pelvis. DVT is not always dangerous, but if the clot becomes large enough, the effects can be fatal.
What are the symptoms of DVT?
One ankle being far more swollen than the other can be a symptom of DVT. However, finding that both ankles are a bit swollen is pretty common on long flights, and not necessarily cause for alarm.
Localized pain or tenderness within a calf or thigh muscle is a possible symptom of DVT, and more serious symptoms are the onset of a cough, increased heart rate, breathlessness, chest pain, or palpitations.
Who is at risk from DVT?
Passengers on long-haul flights are at greater risk of getting blood clots or DVT. The following factors may contribute to a higher risk of DVT during air travel: being a smoker, being over 40, taking oral contraceptives, being overweight, having undergone major surgery recently.
What causes DVT during air travel?
Two main factors contribute to the incidence of DVT on airline flights. First is the low humidity level. When you become dehydrated, blood thickens and is more prone to clotting. Second is a lower level of physical activity. As there are limited opportunities to move around on planes, circulation is reduced. Cramped seating may cause pressure points on the legs that slow blood flow locally, which can increase the chances of clotting.
Quick tips to avoid DVT
Arrive early at the check-in desk and try to get a seat with additional leg-room, such as a bulkhead (the partition that divides a plane into different sections) or an emergency-row seat. Note that children and passengers with disabilities will not be seated in exit rows.
- When sitting, move your ankles around – point and flex.
- Don’t take sleeping pills that knock you out for hours and leave you motionless.
- Ask your doctor if you should wear support hose to improve circulation.
- Avoid sitting with your legs crossed and avoid clothes that are too restrictive.
- Ask your doctor about aspirin before air travel, as it can keep blood from clotting.
