Instead, open the window fully to ensure a rapid and complete exchange of air. What’s more, this kind of ventilation isn’t good for the environment.

The duration should be adjusted according to the weather to ensure fresh air circulates throughout the entire living area. What’s more, fresh air boosts your ability to learn.
