Which is better for air conditioning, energy saving and healthy sleep mode?

The health and energy saving of air conditioner is more energy-saving than that of sleep mode. Because the temperature automatically set in energy-saving mode is between 26-28 degrees, the energy-saving mode of air conditioner is mainly to avoid setting too low and keep running, while the sleep mode can usually minimize wind speed and reduce noise and airflow. In order to facilitate sleep, sleep mode is relatively more energy-saving.
