It is preferred not to sleep on the plane, during take-off and landing, as this helps to avoid health problems, said Gregory Lugovoy, a travel and transportation expert director of Biletix. According to the Russian "Novosti" agency.
He added, that during the rest of the flight, it is possible to enjoy and sleep peacefully, and it is important to choose the appropriate conditions for that.
Lugovoy said: "Sleeping during takeoff and landing can be risky and unsafe for health: a major change in pressure occurs in the cabin of the plane, so the channel that connects the middle ear cavity to the pharynx - Estacius tube - is narrowing. If one does not swallow saliva or Yawns at the right time, as it may lead to the beginning of nosebleeds and headaches, and in more serious cases - damage to the eardrum. "
The expert stressed that taking off and landing are not only the most dangerous moments during the entire trip, but are extremely important from the point of view of caring for self-health.
