How to solve the problem that southerners don't adapt to the dry environment in northern winter?

It is cold in the north, and the water molecules in the air are saturated and turned into water droplets, which makes the air dry. This is caused by nature, and the best way is to adapt to it. Southerners have an adaptation process when they come to the north. Many of my teachers are from the south. They went to the north in the fifties and sixties, when there were no health products. The experience of a Guangdong teacher is to eat more carrots and radishes, don't wear cotton-padded clothes too early, and keep warm indoors. Now their family is no different from northerners in adapting to the weather.

I hope this experience will help you.
