Then you seem to have trouble reading, because I fully contradict you. Drinking water is sufficient to counterbalance the dry air. You don’t need soup for that.

Water is only bad for you if you consume an insane amount of it.

Best way is to neatly lay the sheets open during the day. Looks better than completely messy, and is healthier.

This is not true unless you drink 6 liters at once, and even the driest winter won’t dehydrate you even remotely that much.

Soups are great, this reasoning is absolutely not. Sorry.
