Many people recognize this: waking up or ending the day at home with a headache, even when there is no obvious reason for it at first glance. Indoor air quality can play a role in this, although it is by no means the only possible cause. On its page about unhealthy indoor air, the Lung Foundation points out that symptoms caused by polluted air often disappear quickly as soon as you leave the room or provide extra ventilation. That is an immediately useful clue.
Which factors in indoor air can play a role
A high CO2 level
In a small, poorly ventilated room, the CO2 level can rise significantly, especially if several people are present or if doors and windows remain closed for a long time. At an elevated CO2 level, many people report symptoms such as a heavy head, reduced concentration, and fatigue. Only ventilation with fresh outdoor air lowers the CO2 level; an air purifier does not.
Volatile Organic Compounds (VOCs)
Paint, cleaning products, furniture, and even some scented candles can release volatile organic compounds. For sensitive individuals, prolonged exposure can contribute to headaches and irritated airways. The Lung Foundation mentions VOCs, along with CO2, particulate matter, and moisture, as part of the mixture of substances that you breathe indoors.
Particulate matter
Cooking, candles, a fireplace, and traffic outside can bring particulate matter into the home. Some people are more sensitive to this than others and notice that their symptoms increase on days with high levels of particulate matter indoors.
Air that is too dry or too humid
Both very dry and very humid air can contribute to a trapped, stuffy feeling, which some people experience alongside headaches. A relative humidity between 40 and 60 percent feels most comfortable for most people.
What you can do yourself
- Ventilate regularly. Open windows opposite each other briefly several times a day for a quick refresh of air and a lower CO2 level.
- Limit sources of VOCs. Where possible, choose low-emission paint and cleaning agents, and allow new furniture to off-gas in a well-ventilated room.
- Reduce particulate matter while cooking. Use the extractor hood and, if possible, open a window.
- Keep the temperature moderate. A room that is too warm can also contribute to headaches.
The role of an air purifier
An air purifier does not lower the CO2 level; only ventilation can do that. For particulate matter, VOCs, and other particles in the air, an air purifier with a HEPA13 and activated carbon filter can make a difference. In our experience, the AirPure Plus PA244 is a good supplement to regular ventilation, thanks to the 4-stage filtration that, in addition to particulate matter, also filters some of the VOCs from the air.
If the headache persists despite adjustments to the indoor air, it is wise to discuss the symptoms with a doctor, as headaches can have many different causes. View the full range at dynter.eu.
