The advice is almost folkloric. Get out of the cold. Move somewhere dry. The joints will thank you. For a long time, the migration of retirees with stiff knees from northern winters to Arizona, Florida, and southern Spain was treated as evidence that the advice worked.

This article looks at what the evidence shows and what to weigh before treating climate as a medical intervention.
