If it does dehydrate us from the inside, then is increasing our water consumption adequate? I suppose there are health places with information on "rehydration" for those with dry skin, etc.
Course, in Florida, we have staggeringly high humidity much of the time, so PG could be slathered on our skin to draw moisture from the air. But its reverse point is 70% relative humidity: Air-conditioned buildings and even outdoor air in many parts of the country are below that figure, meaning moisture would leave the skin where PG has been applied. It would dry out that area of skin.
We put PG on our throats and lung surfaces.
One concern that could come up: Dry throat and nasal passages are a welcome mat for rhinoviruses during cold and flu season. It's arguable, but some researchers think we carry these viruses year 'round, and that they are activated by cold air and enter through cracks in dry throats. A red, raw throat is .. dry, and microscopically as cracked as a dried-up lake bed.
I reported a story years ago on a plant researcher who tracked a particular crop-food virus only to discover that the virus was dormant until the overnight temperature dropped below 60 degrees. It then sprang to life and attacked the plant. He thought his findings might have some application to viruses that make us ill.
