Although modern commercial aircrafts offer rapid, convenient, and safe transportation, some passengers with illnesses may be affected by the cabin environment. The cabin environment is limited by the aircraft design and is quite different from land transportation. These differences include low pressure at high altitudes (low oxygen level and cabin pressurization effect due to the low pressure in the cabin), cabin environment characteristics (poor air quality and low humidity in the cabin), jet lag, airsickness, and a long stay in a confined space. Please pay attention and take proper preventive measures.

• While descending, if you feel discomfort in your ears or sinuses, try to swallow, chew, or open your mouth wide to promote better airflow. If your child has these problems, try giving him or her a drink or a pacifier to promote better airflow and relieve discomfort.
• Avoid flying within 24 hours of scuba diving.
• If you are prone to airsickness, reserve seats near the aircraft wings.
• Avoid heavy meals, alcohol, and caffeinated drinks while on board. Drink more water and juice.
• Standing up suddenly after waking may cause dizziness. This can be the result of alcohol consumption, low oxygen, low activity, and sleepiness. We suggest that you stretch and do exercises in your seat before standing up.
• Although cabin air quality is better than that of a home or office, an aircraft cabin is a public area where cross-contamination is possible. We suggest that you do not fly if you have a contagious disease.
• Avoid wearing contact lenses during your flight.
• We suggest that you use a skin moisturizer.

Advice from Aviation Doctor

Flying should be a safe and enjoyable experience. You can enjoy your trip if you understand the characteristics of the cabin environment, consult your doctor, and make necessary medical care arrangements before departing. Here is some advice for in-flight health care. Before departure:

• Make sure that you do not have an immune system disease.
• Do not ride an aircraft if you feel any discomfort.
• Wear loose and comfortable clothing.
• Consult physicians on any health issue and tell the airline about your problems while making a reservation.
• Carry necessary medicine with you.
• Avoid sitting still for a long period of time. Do exercises in your seat to move your leg muscles and joints.
• While the aircraft is descending, stay awake and relieve discomfort in your ears and sinuses as early as possible.
