Humidity in the home is a decisive factor for well-being and health. Optimum humidity can not only improve the indoor climate, but also prevent health problems. But what is the ideal humidity in rooms and how can you regulate the humidity in your living space? This article will tell you everything you need to know about humidity in the home.

Why is humidity important?

Humidity has a significant impact on our well-being and health. Humidity that is too high or too low can lead to health problems and have a negative impact on the indoor climate. Optimum humidity helps to prevent respiratory diseases, strengthen the immune system and improve the ability to concentrate. It also plays an important role in the preservation of furniture and building structures, as extreme humidity levels can damage both wood and other materials.

What is the optimum humidity level in the home?

The ideal humidity in rooms is between 40 % and 60 %. Most people feel most comfortable in this range, and the risk of mould growth and other humidity problems is minimized. Too high humidity can promote mold and mites, while too low humidity can lead to dry skin and airways. Especially in winter, when heating air reduces humidity, it is important to keep an eye on humidity levels.

Causes of high humidity

High humidity in the home can be caused by various factors:

  • Cooking and showering: These activities release a lot of moisture that accumulates in the air.
  • Poor ventilation: Inadequate ventilation can increase humidity as the moist air cannot escape.
  • Leaky windows and doors: These allow moisture to penetrate from outside and increase the humidity inside.
  • Aquariums and houseplants: These can also help to increase the humidity.
  • Drying laundry: Drying laundry indoors can significantly increase the humidity.

How can you reduce the humidity in your home?

You can take the following measures to reduce the humidity in your home:

  • Ventilate regularly: Open the windows several times a day to improve air circulation and remove moist air to the outside. Shock ventilation is particularly effective here.
  • Use dehumidifiers: These devices are effective at removing excess moisture. They are particularly useful in rooms with high humidity, such as bathrooms or basements.
  • Reduce plants: Some plants increase humidity, reduce their number or choose plants that require little water.
  • Cooking with an extractor hood: Use an extractor hood when cooking to channel steam directly outside.
  • Bathroom fan: Run the fan in the bathroom after showering to remove moisture more quickly.

How can you increase the humidity?

In some cases, the humidity can be too low, especially during the heating period in winter. Here are some tips to increase the humidity:

  • Use a humidifier: These devices help to increase humidity and are particularly useful in bedrooms or living rooms.
  • Dry laundry indoors: This can help to increase humidity, but should be used with caution to avoid mold growth.
  • Set up bowls of water: Place bowls of water on the radiators to encourage evaporation.
  • Houseplants: Certain plants, such as the bow hemp or the rubber tree, can help to increase the humidity.

Tips for achieving optimum humidity in the living space

  • Correct heating: Keep the room temperature constant to regulate the humidity. A temperature of 20-22 °C in living rooms is ideal.
  • Use humidity sensors: These help to monitor the humidity in the living space. Hygrometers are easy to use and very useful.
  • Prevent mold: Avoid moisture accumulating in corners and behind furniture by ventilating regularly and moving furniture away from the walls.
  • Check seals: Regularly check the seals on windows and doors to ensure that moisture is not penetrating.
  • Improve insulation: Good insulation can help to better control the temperature and humidity in the home.

Effects of humidity that is too high or too low

Excessive humidity can lead to mold growth, which can cause health problems such as allergies and respiratory illnesses. Mold can also damage building structures and lead to expensive repairs. Humidity that is too low can dry out mucous membranes and promote infections. It can also dry out and damage wooden furniture and floors. In addition, insufficient humidity can increase static electricity, which can be particularly troublesome in areas with a lot of electronics.

Long-term strategies for controlling humidity

Long-term strategies to control the humidity in your home can help you create a lasting healthy living environment. Here are some approaches:

  • Integrated ventilation systems: Invest in an integrated ventilation system that automatically regulates humidity. These systems are particularly effective in new buildings or renovations.
  • Regular maintenance: Have heating and ventilation systems serviced regularly to ensure that they work efficiently and regulate humidity correctly.
  • Adapt the construction method: When building or renovating a house, look for materials that regulate moisture well, such as breathable paints and wall coverings.

The right humidity level in the home is crucial for a healthy and comfortable living environment. Simple measures such as regular ventilation and the use of dehumidifiers or humidifiers can help you achieve optimum humidity levels in your home. Make sure you regularly monitor the humidity in your living space to ensure an ideal indoor climate. These tips should answer all your questions about humidity in the home so that you and your family can live in a healthy environment.

Understanding and controlling humidity levels are essential aspects of a healthy living environment. By following the steps above, you can ensure that your home remains comfortable and health risks are minimized. Remember that both too high and too low humidity levels can have long-term effects on your health and your home. Therefore, it is important to find a balance and maintain it.
