Can I do something to prevent outside cool air being drawn into the house when I turn on the exhaust fan in the bathroom?

In winter if I turn on an exhaust fan in the bathroom, the outside cool air will be drawn into the house (reverse effect in summer) lowering the efficiency of the AC, is this normal? Or can I do something to prevent this?
