Equilibrate the pressure in the ears. Because the air pressure changes in the passenger cabin during take-offs and landings, there may appear slight pressures in the ears. In order to avoid such situations it is recommended to have sugar candies with you or ask them from the stewardesses. Infants endure more difficult during the flights, that is why be sure you have the baby soother.
Dehydration. Try to drink plenty of water and juice during the flight. Avoid drinking much tea or coffee – being diuretics, they contribute to dehydration.
Try not to use contact lenses during the flight. The excessive dryness of the air in the aircraft cabin may lead to irritation of eyes. That is why doctors recommend use of eyeglasses instead of contact lenses during the flight.
Comfortable position during the flight. Comfortable position during the flight is extremely important. Remove all items that impede normal circulation of the blood. Use the seat belts and make yourself comfortable.
Jet-Lag. Usually jet-lag lasts as many days as many time zones the passenger crosses during her/his trip to the point of destination. In order to avoid side effects of adaptation to the local time (acute condition of bronchial asthma, rheumatism, cardiovascular diseases etc.) we recommend you to relax during the period of adaptation, to have a rest, to read, walk in the park, etc. This will help you to overcome the process of adaptation more quickly and smoothly and will make negative effects of the environment (such as temperature drops etc.) less painful. Good sleep before the flight will help to prevent insomnia, over fatigue, appetite loss and other negative effects of adaptation.
Blood circulation. During the flight avoid staying motionless. This may lead to an abnormal flow of the blood to certain parts of the body and on the other hand. Make difficult circulation of the blood to the inferior members. Simple physical exercises that can be done during the flight will prevent appearance of fatigue and edema. Sit comfortably and change your body position as often as possible. Do the same thing when you sleep.
