If you travel long distances by plane on Korean Air flights, it is helpful to know some health tips to make your flight more comfortable. The temperature inside Koran Air's flight cabin is kept between 10pm and midnight, which is a very comfortable temperature. It is always better to wear comfortable clothes that are not too thick but that always have a light sweater or jacket in hand luggage in case it is cold.
The humidity inside the cabin of Korean flights is kept at a level of 15 percent. The comfortable humidity level for the average person is 50 to 60 percent. The 15 percent level on Korean Air flights is already considered dry. With dry humidity, body moisture tends to evaporate. The skin and membranes of the eyes and nose also begin to dry out during the flight and can become quite uncomfortable when this happens. The best thing to do on Korean flights is to keep yourself hydrated by drinking lots of water, fruit juice or any type of liquid drink. Avoid drinking coffee and tea because these drinks can only cause further dehydration. Passengers with contact lenses must remove them during Korean flights to avoid dry eyes which could cause eye inflammation.
The atmospheric pressure within Korean flights is set at the altitude of 5,000-8,000 feet. There is a tendency that deafening of the ears can occur. This is caused by the change in pressure inside Korean Air flights when they land or take off. To avoid ear deafness, chew on some gum or simply move your jaw up and down as if you were chewing gum. You can also try closing your mouth and then pinching your nose as you slowly exhale the air.
