Core Viewpoint - The article discusses the appropriate use of air conditioning during hot summer months, emphasizing the balance between comfort and health risks associated with temperature settings and prolonged exposure to cold air [2][3][4][5][6]. Group 1: Air Conditioning Temperature Recommendations - Recommended indoor air conditioning temperature for public spaces is not lower than 26 degrees Celsius, balancing health, comfort, and energy efficiency [3]. - A reasonable temperature range for home use is between 24 to 28 degrees Celsius, with adjustments based on age and activity levels [3]. - For sleep, it is suggested to set the temperature 1 to 2 degrees higher than daytime settings to avoid disrupting deep sleep [3]. Group 2: Health Risks Associated with Air Conditioning - Rapid temperature changes between indoor and outdoor environments can lead to discomfort; maintaining a temperature difference of no more than 10 degrees Celsius is advisable [4]. - High humidity levels (above 60%) can lead to discomfort and health risks, while low humidity (below 40%) can cause dryness and respiratory issues [4]. - The concept of "air conditioning disease" is discussed, highlighting that prolonged exposure to closed environments can lead to a buildup of CO2 and pathogens, causing symptoms like dizziness and fatigue [5]. Group 3: Dietary Considerations in Hot Weather - Consumption of cold foods and drinks can lead to digestive issues, especially in summer when the body is already under heat stress [6]. - Natural foods like watermelon and cucumber are recommended for hydration without burdening the digestive system, while artificial frozen foods should be limited [6]. Group 4: Special Considerations for Vulnerable Populations - Infants, pregnant women, and the elderly require specific temperature settings and precautions when using air conditioning to ensure comfort and safety [8][9]. - Chronic illness patients, such as those with asthma or skin conditions, need to be cautious with temperature settings to avoid exacerbating their symptoms [9].
