Infants taking high-speed railways generally do not have special effects on their ears.
1. Occasionally, high-speed railways will pass through tunnels and the speed of the train will not change rapidly and drastically, so the air pressure in the carriages is relatively constant, and among healthy infants, there is no special impact on the eardrums, inner ears and other hearing organs in general.
2. Some infants suffer from otitis media, and if they have to pass through tunnels or caves when taking high-speed railways, the pressure outside will be higher than that inside the ear canal, which may cause infants’ earache, stuffy ears, crying and other uncomfortable symptoms. To avoid adverse effects, you can cover both ears of the infant appropriately to minimize the impact of this pressure difference on the ear.
All in all, healthy infants can take high-speed railroad, but try to avoid taking high-speed railroad during the period of ear discomfort, and if there is any discomfort, it is recommended to consult the regular hospital in time.
