Why do you have to sleep in a well ventilated room?

Sleeping in a well-ventilated room is important because it helps maintain optimal air quality and temperature, which are crucial for restful sleep. Good ventilation allows for the circulation of fresh air, reducing the buildup of carbon dioxide and other pollutants. This can improve oxygen levels and promote deeper, more restorative sleep. Additionally, proper airflow can help regulate body temperature, making it easier to fall asleep and stay comfortable throughout the night.
