1. A method for operating a wind turbine, wherein the wind turbine includes a nacelle having a nacelle component and a nacelle air flow influencing unit, wherein the nacelle air flow influencing unit is configured to influence an air flow which is at least one of entering, flowing through and exiting the nacelle, the method comprising:
determining an operating condition of the nacelle component;
determining a cooling demand of the nacelle component dependent on the determined operating condition of the nacelle component;
controlling an operation of the nacelle air flow influencing unit dependent on the cooling demand of the nacelle component to adapt the air flow to the cooling demand of the nacelle component;
determining a load condition of a load acting on a rotor bearing; and,
determining the operating condition of the rotor bearing dependent on the determined load condition.
