Healthy Travel
Maintaining the same posture during a flight may lead to discomfort. We recommend that you exercise your legs in your seat from time to time to help relax your muscles. Cabin air pressure changes may cause some discomfort during a flight but most symptoms will disappear after landing. If you have an emergency situation, please contact one of our flight attendants immediately.
Jet Lag
Symptoms
Symptoms include fatigue, slower reaction, memory loss, and inability to concentrate. Lack of sleep also leads to tiredness, headache and dizziness.
Causes
When you travel by air, you are likely to move from one time zone to another constantly and quickly, which means your 24-hour biological cycle and bodily functional patterns will be disrupted to a certain extent.
Recommendations
Upon departure, immediately set your clock to the time of the destination to get yourself prepared mentally for the new time zone.
After reaching your destination, have adequate sleep and avoid straining yourself so that your body can really acclimatize.
If your trip is a short one, try to maintain your activity patterns in the place you come from, which will help you avoid double jet lag.
Altitude Flatulence
Symptoms
Symptoms include bloated stomach and abdominal pain.
Causes
Due to air pressure changes, gas in organs such as gastrointestinal tracts, lung, middle ear cavity and paranasal sinuses cannot be discharged in a timely manner and thus dilates these organs, causing slight pain.
Recommendations
If you have clear symptoms, you can walk around in the aircraft cabin to help discharge the gas and relieve the pain.
Avoid eating anything one hour before takeoff. Don’t eat too fast, otherwise too much air could end up in your stomach. Before travel, avoid foods with high content of fat that are not easy to digest, carbonated drinks, gas-producing vegetables and soy products and spicy foods that could lead to constipation. Fiber foods are highly recommended.
Earache
Symptoms
Symptoms include tinnitus and hearing loss.
Causes
The air pressures in and outside the ear cavity are quite different. This can cause tinnitus and earache. If you happen to have a cold, a running nose and an inflammatory canal between the back throat and the middle ear (Eustachian tube), the symptoms will be very evident.
Recommendations
You can repeatedly pinch your nose and exhale and swallow to balance the air pressures inside and outside the middle ear and lessen the pressure on your ears. The best way is to take a few chunks of chewing gum with you. Intentional yawning also helps
If you have nasal congestion caused by a cold, you can use nasal drops and do what’s described above while the aircraft is descending.
Airsickness
Symptoms
Symptoms include fatigue, dizziness, facial paleness, cold sweat, nausea and vomiting.
Cervical ailments, high blood pressure, high cholesterol and diabetes could induce airsickness. Airsickness is very common and can inflict pain on travellers of all
ages.
Causes
Speed changes and air turbulences could result in irregular bumps, causing the body to produce sensitivity reactions.
Recommendations
Don’t travel by air with an empty stomach – hunger could exacerbate airsickness instead of alleviating it. Approximately 30 minutes before take-off, you can take some anti-airsickness medicines as advised by a doctor.
During flight, have a paper bag ready. Choose to sit in the central part of the cabin which is relatively stable.
If airsickness symptoms appear, adjust the seat back to the lying position, remain motionless, and take deep breaths, eyes closed.
Diabetes
If you are a diabetic, consult your doctor about the drugs you need to take with you onboard. You can book diabetic meals at least 24 hours before flight departure through Air China’s hotline 95583. If you request special meals in addition to diabetic meals due to health or other special reasons, you should provide an accurate, detailed and clear description of the meals you need. Our service agent then can provide accurate information to our catering supplier to make sure that the meals you truly need can be provided during the flight.
If you fly westward from one time zone to another, the day becomes longer, so you should bring more medicine.
