First tip: Set the air conditioner temperature to 26 degrees Celsius.

26 degrees Celsius is generally recognized as the most comfortable temperature for the human body; a few degrees lower and it will feel chilly. Furthermore, in summer, the temperature difference between indoors and outdoors when air conditioning is on is greater. Temperatures below 26 degrees Celsius expose the body to a larger temperature difference, reducing the body's regulatory ability, lowering immunity, and making one more susceptible to illness. Additionally, for every degree Celsius the air conditioner lowers, its power consumption increases by 7%-10%. Therefore, 26 degrees Celsius is a healthy, comfortable, and energy-efficient temperature.
