Does wood shrink or expand in cold weather?

What happens to wood doors when the weather gets colder?

When the weather begins to cool, doors will deteriorate in two main respects. Each comes about because of wood expansion and contraction in response to changes in temperature and moisture. When the weather gets chillier, the wooden fibres which make up your door will begin to contract. When things get warmer again, those same fibres will expand.

How can I stop internal wooden doors expanding in the winter?
