Our "homes," whatever shape those homes might take (apartments, cottages, dorm rooms, the van in which we full-time travel, etc), tend to relax us. That relaxation isn't a given, especially if there's some other factor we associate with home that pushes us in the opposite psychological direction (a leak in the ceiling, an abusive partner, a baby that stresses us out and keeps us awake), but in general our homes are physical spaces that feel predictable, secure, and us-shaped.
