In our homes, humidity plays a crucial role in the comfort and health of the occupants. Whether you are a decoration enthusiast or a parent concerned about your children’s well-being, understanding hygrometry is essential. Indeed, an adequate humidity level contributes not only to your comfort but also to the preservation of your home. Let’s explore together the importance of this often-overlooked parameter, how to measure it, and the suitable solutions to ensure a healthy environment.
Understanding Hygrometry and Its Impact on Health
Air humidity is a determining factor in our habitat. According to ADEME, an ideal hygrometry level generally lies between 40 and 60%. Outside of this range, problems can quickly arise. An environment that is too dry, with a level below 40%, can lead to discomfort such as skin irritations and allergies. Conversely, excess humidity, above 60%, encourages the development of mold and dust mites, which are responsible for various health issues.

The Ideal Hygrometry Level
To maintain your well-being, it is crucial to keep hygrometry within the norms. A rate between 40% and 60% ensures healthy air. The effects of an imbalance are varied:
- Below 40%: dry air, irritated skin and mucous membranes.
- Between 40% and 60%: optimal conditions, respiratory comfort.
- Above 60%: risk of mold, allergies, respiratory diseases.
Consequences of Excessive Humidity
When the humidity level exceeds the recommended threshold, the consequences for health and well-being are significant. Mold, for example, can develop on walls and ceilings, leading to respiratory problems such as asthma or chronic bronchitis. Dust mites, on the other hand, multiply in humid environments, increasing the risk of allergies. Furthermore, high humidity could contribute to joint pain and blood circulation problems.
| Effects of Excessive Humidity | Potential Consequences |
|---|---|
| Mold | Respiratory diseases, allergies |
| Dust Mites | Asthma, allergic rhinitis |
| Circulation Problems | Joint pain, edema |
Identifying a Home with High Humidity
It is crucial to recognize the signs of excessive humidity in your home. Here are some indicators to watch for:
- Warped or bulging woodwork.
- Peeled or flaking paint.
- Presence of mold on walls or ceilings.
- Persistent bad odors.
- Condensation on windows.

Solutions for Measuring and Regulating Hygrometry
To ensure your environment remains healthy, it is essential to measure the humidity level. A hygrometer, whether electronic or mechanical, will provide you with an accurate reading. It is advised to keep this device away from heat sources to avoid erroneous readings. Once the level is measured, it is possible to take action to regulate the humidity level.
Various solutions are available to you:
- Use a humidifier to increase the humidity level in case of excessively dry air.
- Install a dehumidifier to reduce excessive humidity.
- Ensure proper ventilation in rooms, especially those with high humidity like the bathroom.
- Avoid water accumulation on surfaces and check for any leaks in your spaces.
Preventing Humidity Problems in Your Home
Preventing humidity is just as essential as knowing how to remedy it. Here are some tips to avoid the accumulation of humidity:
- Ensure adequate ventilation, especially in humid rooms.
- Invest in moisture-resistant materials, such as suitable plasterboards.
- Use moisture absorbers from brands like Ecovacs, Xiaomi, or Buffalo.
- Regularly check the tightness of your plumbing, especially in areas prone to leaks.
