I believe the guard nodes get changed periodically but remain the same for weeks unless you clear the state.
If you use bridges they take the place of a guard node and you will want to share otherwise it’s easy for an observer to associate inputs and outputs.
Using a vpn to connect to a bridge can provide some additional protection of your origin IP even if your bridge/guard mode is discovered.
