Equilibrate the pressure in the ears. Because the air pressure changes in the passenger cabin during take-offs and landings, a slight pressure in the ears may appear. In order to avoid such situations, it is recommended to have sugar candies with you or ask them from the flight attendants. Infants endure the flights it with more difficulty and this is why you have to be sure to have take a 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 the irritation of eyes. That is why doctors recommend the 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 blood circulation. Use the seat belts and make yourself comfortable.
Blood circulation. Avoid staying motionless during the flight. This may lead to an abnormal blood flow to certain parts of the body and on the other hand it makes the blood circulation difficult to the inferior members. Simple physical exercises that can be done during the flight will prevent the appearance of fatigue and edema. Sit comfortably and change your body position as often as possible. Do the same thing when you sleep.
