How can I prevent or alleviate a dry throat after a plane ride?

To prevent or alleviate a dry throat after a plane ride, you can stay hydrated by drinking plenty of water before, during, and after the flight. You can also try using a saline nasal spray to keep your nasal passages moist, as dry air in the plane can contribute to a dry throat. Additionally, sucking on lozenges or Chewing Gum can help stimulate saliva production and keep your throat moist.
