As temperatures rise, many people tend to keep windows tightly closed and turn on the air conditioning upon entering indoor spaces. A university student expressed bewilderment as their teacher insisted on keeping windows open while using air conditioning to prevent stuffiness. However, online responses were divided, with some emphasizing the importance of air circulation for indoor air quality and others mentioning expert advice suggesting leaving windows slightly open to maintain air circulation even when using air conditioning for better health conditions and environmental awareness.
