How can I tell if the air in my home is dry? How can I regulate indoor humidity? In what ways can dry air negatively affect health? What are some free methods to control humidity indoors? Do I really need a humidifier?
As the heating season begins, one of the common issues we face is dry air in our homes. Regardless of whether you heat your home with an air conditioner, electric heaters, or radiators, heating inevitably leads to drier indoor air.
Why Is Dry Indoor Air Harmful?
A particular problem with dry indoor air is that many people aren’t aware of it, attributing symptoms instead to viruses, reduced immunity, colds, and so on. In fact, dry air can have a very negative impact, especially on young children and people with respiratory issues.

Dry air dries out the respiratory passages, making it harder for them to trap dust particles, which can then reach the lungs. It also leads to skin and eye irritation. These issues are often mistakenly attributed to other health conditions, but it’s actually easy to determine if indoor air is too dry—and just as easy to regulate its humidity.
How to Tell if the Air in Your Room is Too Dry
The easiest way to check the humidity in your home is by purchasing a hygrometer. It’s an inexpensive device, and reliable models that measure both temperature and humidity can be found for just a few dollars. Many digital clocks also come with built-in humidity sensors.
For indoor air to be considered healthy for everyone, including sensitive household members, the humidity should ideally be between 30 and 60 percent, with an optimal level of around 45 percent. If it drops to 20 percent, it’s time for concern.
How to Efficiently Regulate Humidity in Your Home
There are several ways to maintain optimal indoor humidity. The simplest method is ventilation. Generally, airing out your home three times a day for three to five minutes is enough to replace stale indoor air with fresh air without significantly lowering the room’s temperature.
It’s important to note that from an energy efficiency perspective, it’s better to ventilate briefly and intensely than to leave windows cracked open for extended periods.
What If Ventilation Isn’t Enough?
In most cases, ventilation will be sufficient to maintain proper humidity. Another option is to grow houseplants, though the exact number needed to effectively control humidity isn’t well established. Additionally, space constraints in many homes can make it challenging to incorporate enough greenery to make a difference.
A much simpler method is to place containers of water on your radiators, which effectively regulate humidity. If you have an electric heater, you can place a small pot of water on it. You can even add a few drops of essential oil for a pleasant fragrance. Just make sure to regularly change the water and clean the containers to prevent bacterial growth.
Finally, if none of these solutions work, you could consider purchasing a humidifier. However, this is usually an unnecessary expense, as one of the previous methods should be effective.
