Introduction
Think about it: we spend a large part of our day indoors—in our living room, kitchen, or bedroom. Yet, we rarely think about the air we breathe there.
Only when it suddenly feels stuffy inside, the air is dry, or you simply have to "get away" from a room do you realize how much of an impact your home actually has. It's the backdrop to your day, and that backdrop matters.
This article follows on from our overview:

What exactly is "indoor air"?
Indoor air isn't just the air that flows in through open windows. Its quality is determined by several factors: first, the ventilation of the room; second, the comfortable temperature; third, whether the air is too dry or too humid; and fourth, the frequency of air exchange.
These factors together determine whether you feel comfortable – or whether you unconsciously feel the need to leave the room.
How does a room start to feel “boring”?
Some signals are very obvious: a musty smell, a stuffy feeling or the realisation that the window has not been opened for hours.
But often these signals are more subtle and you usually notice them yourself first:
You feel more tired or have difficulty concentrating, you suddenly focus on your breathing or you just want to open the window right away.
Your body often senses this before you even realize it. It's a subtle signal: your surroundings need a refresh.
Daily habits that affect indoor air quality
Many things we take for granted have a significant impact on indoor air quality:
For example, keeping the windows closed all day to stay warm, not using the extractor hood while cooking, keeping the heating at the same temperature all day and spending cozy evenings with friends in the same room.
These are all very common habits. But that's precisely why they emphasize the importance of consciously breathing fresh air.
Small changes can make a big difference
Fortunately, you don't need to carry out major renovations to improve air quality. A few everyday habits can help:
1. Breathe fresh air every day: For example, open several windows at the same time in the morning for quick and effective ventilation.
2. Ventilate after "wet" activities: Make sure you open windows or use a ventilation system during and after showering or cooking.
3. Maintain a comfortable temperature: In general, a lower room temperature makes breathing cooler and more comfortable.
Keep an eye on humidity: Air that's too dry (e.g., from a heater) can be irritating. Placing a bowl of water on the radiator can improve humidity.
The goal isn't a perfect, clinical environment. It's about balance, and a home where the air helps you relax instead of subtly draining your energy.
