Air pollution: Living in urban areas can expose you to smog, vehicle emissions, and industrial pollutants, which may affect lung health and overall well-being.
Mold spores: In humid climates, open windows can allow mold spores to enter, potentially aggravating asthma or respiratory issues.
2. Exposure to Noise and Light Pollution
Open windows can let in unwanted noise and light, which can disrupt sleep cycles:
Street noise: Cars, sirens, and barking dogs can reduce sleep quality and cause frequent awakenings.
Artificial light: Streetlights or passing vehicles can disturb the production of melatonin, the hormone that regulates sleep.
