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

[PrestonFitz]

In summer, the car air conditioning is generally set at 26℃, as the comfortable temperature range for the human body is between 24℃ and 27℃. Additionally, the local weather temperature should be considered, and the temperature difference between indoors and outdoors should not exceed 5℃. If the air conditioning temperature is set unscientifically in summer, leading to a large temperature difference between indoors and outdoors, it may cause air conditioning-related illnesses. Common air conditioning-related illnesses include the following four types: 1. Respiratory diseases: Once cold air breaches the fragile "defense line" of the respiratory tract, it can cause symptoms such as coughing, sneezing, and a runny nose, which are signs of upper respiratory tract infections. 2. Brain nerve disorders. 3. Joint pain. 4. Skin allergies: For chronic skin conditions, sweating in hot weather can significantly irritate the skin, causing unbearable itching; staying in an air-conditioned room for too long can also lead to dry skin and itching.
