What is the best temperature for car air conditioning in summer?

Generally, it is recommended to set the temperature at 26°C, as the comfortable temperature range for the human body is between 24°C and 27°C. Additionally, the local weather temperature should be considered, and the indoor-outdoor temperature difference should not exceed 5°C. Here is some relevant information: 1. The most suitable air conditioning temperature for the human body should be between 24°C and 27°C, preferably not lower than 22°C. The indoor-outdoor temperature difference should not exceed 5°C, and the air conditioning temperature at night should not be lower than 24°C. If the air conditioning is set too low, the indoor temperature may become too cold, leading to "air conditioning sickness," which can cause symptoms such as colds, coughs, fever, and fatigue. 2. Many people, when faced with a hot car, immediately start the engine, turn on the air conditioning, and set the fan speed to maximum to achieve the fastest cooling effect. However, this method does not actually cool the car interior quickly. 3. The correct approach is to first open all four windows to allow cross-ventilation, which helps the car interior temperature quickly equalize with the outdoor temperature. Then, close the windows and turn on the air conditioning in recirculation mode for cooling.
In summer, I find setting the car air conditioner to around 24°C most comfortable. Too high a temperature can easily lead to heatstroke, but setting it too low, such as below 20°C, can make you shiver when entering the car from the hot outside, which is bad for breathing, especially for families with elderly or children—temperature differences should not exceed 5°C. Maintaining this range while driving keeps me neither too hot nor too cold, ensuring a calm mood without irritation. The automatic air conditioner is a great help, as it adjusts the airflow automatically to save energy. Don't forget to ventilate by opening the windows before closing them, or use sunshade films to reduce interior heat. Prolonged direct exposure to air conditioning can also cause back pain, so I always remind myself to adjust the airflow direction to protect my health. Overall, 24°C is safe and practical for most people.
