Why can not sleep during takeoff and landing aircraft

Sleep during takeoff and landing can seriously damage the ears.

The fact is that at this time drastically changes the air pressure in the cabin. When the aircraft is climbing, there is a difference between the pressure in the tympanic cavity and of ear atmospheric. The air pressure on the eardrum, eustachian tube lumen becomes narrower. From this phenomenon in human ears pop.

Heavy congestion not only causes excruciating pain, but also can lead to dizziness, epistaxis, ear infections, damage to the eardrum, and even hearing loss.

If you sleep, you will not be able to take measuresTo reduce the pressure on the eardrum. You will not be able to activate the muscles that open the eustachian tube and middle ear supplying air.

Sleep during a flight, of course, possible. Just wait a few minutes from the start of the flight and try to wake up before planting.
