When you open a fridge or a freezer and then close it again, why does it become harder to open again right after?

Vacuum. Temperature and pressure are related. You open it and let a lot of warm air in, and now you close it and that air starts to cool.
Due to their relation, a drop in temperature means a drop in pressure – now the door is actively being sucked close due to pressure differentials.
