Heating/Cooling: Is it better to leave the Bedrooms doors open or closed? ? - family heating and cooling

I live in a house with a 2-storey family (BRS are above). Is it better to leave the door open or closed to BR? I was told to remain open, as it improves the circulation of air above. In addition, all rooms have air conditioning registers blowing air and intake air.
