Airing is a natural habit for most people. Morning rituals often include a thorough airing out of the bedroom and the bathroom after showering. Similarly, many people instinctively open the windows to let in some fresh air after cooking and cleaning, or when they return home. These actions reflect a desire to keep the home smelling sweet and fresh, and a concern for the health and well-being of the family. In fact, letting fresh air into your home gives a sense of belonging and feeling at home. On a warm day it is very pleasant to feel the breeze through the windows, letting in the smells and sounds of summer and activating all your senses. When you air out your home, you take control of it, remove the boundaries between inside and outside, and make it an active and inhabited place.
Ventilation serves two main purposes: 1] It provides healthy and comfortable indoor air; 2] It ensures good thermal comfort (preventing or reducing overheating in warm periods).
