Moisture at Home – What is the Optimal Humidity Level


The majority of the time, when we hear the word humidity, we probably briefly travel to lush tropical woods, where humidity is vital to the environment of the planet. Even while humidity is a natural phenomenon, having too much or too little of it at home might be problematic. Thus, the issue that needs to be answered is: What is the ideal humidity level in our homes?


In today’s article, we will explore the concept of an optimal home by examining the impact of humidity on our daily lives and what causes its increase and decrease in our living spaces.


Lets begin!


What is humidity at home?

Humidity is a measurement that determines how much water vapor is present in the air.

Higher air temperatures are capable of holding more moisture than lower temperatures, therefore Often, when humidity is mentioned, people tend to imagine views of tropical forests. With the introduction of central heating systems and improved energy-efficient insulation nowadays, without considering ventilation, individuals often overlook the fact that tropical microclimates are inadvertently created in homes. This can lead to various health issues for occupants and also impact the construction of the buildings we live in daily


What is optimal humidity levels at home?

The ideal home humidity varies within a broad range and depends on the season. If your humidity meter shows a result between 30% and 60%, there is generally no cause for major concern. Despite this range, maintaining such humidity levels can be challenging, so it is advisable for individuals to monitor it consistently. This can be determined using a humidity meter, which can be purchased online for around €10.

As mentioned, optimal humidity levels in homes change with the seasons, although the range difference is relatively small. Both in winter and summer, the humidity level falls within the 30%-60% range, with a 10% variation in the respective ranges:


Optimal home humidity level in summer: 40%-60%

Optimal home humidity level in winter: 30%-50%


A very high humidity value exceeds 65%, whilst excessively low humidity is less than 25%. Residents should keep an eye on the humidity levels throughout the year.


What causes humidity in homes?

As we have learned earlier, humidity is water vapor in the air, so it is understandable that high humidity is an excessive amount of water vapor trapped in your home. The next question arises – where does humidity come from?


From ourselfs!

Yes, excessive humidity mainly arises from human activities. Our daily lives generate significant moisture. Referring to a study by the UK’s Chartered Institution of Building Services Engineers (CIBSE), everyday activities contribute to humidity in the following proportions:

  • Sleeping: 40g of water per hour through sweating and breathing.
  • Household cleaning: 90g of water per hour through sweating and breathing.
  • Cooking with a gas stove: around 3000g per day.
  • Cooking with an electric stove: around 2000g per day.
  • Dishwashing, using a dishwasher: around 400g per day.
  • Laundry washing: around 500g per day.
  • Indoor clothes drying: around 1500g per day.

As is obvious, it does not take much to raise humidity levels in homes, and it is critical to identify strategies to prevent it. We recommend reading our article on condensation, which examines the development and prevention of condensation as they relate to the quantity of moisture in the home.

It’s important to note that high humidity levels in the home might be an early warning sign of more serious problems, such as leaking pipes or structural damage. By constantly monitoring humidity levels in your house, you can obtain early indicators of more significant issues.


How does reduced humidity occur in homes?

Low humidity in homes is generally less common. It is most often observed when air conditioning or dehumidification systems are excessively used, and/or moisture-collecting devices are in place. Reduced humidity can also occur when a person’s living space is heated while the outside temperature has already increased. This type of situation is very characteristic, especially during the spring period.


Three signs indicating that the humidity level in your home is too low or too high.

As mentioned, with the acquisition of a humidity meter, you will no longer need to guess whether the humidity in your home is high, low, or ideal. However, there are also some signs that may indicate that your living space does not have the optimal humidity level.

These signs include:

  • Breathing problems: If you have difficulty breathing or often feel a tightness in the chest, it may indicate a high humidity level.
  • Poor sleep: Both too high and too low humidity levels can affect your sleep. Low humidity creates dry air, which can irritate the throat, while high humidity makes the body work harder, leading to discomfort and restlessness.
  • Poor body temperature regulation: If it is always too hot or too cold, it is necessary to adjust the indoor humidity level as carefully as heating.
  • Unpleasant air quality: If you notice unpleasant odors or see mold, it could be a sign of excessive humidity and poor ventilation.

By paying attention to these signs, you can get an idea of whether your home has an optimal humidity level.


How to manage humidity throughout the year?

The best solution and the most significant recommendation is … Air exchange or Ventilation! Air circulation in the home is the most crucial solution if you want to prevent condensation and maintain a healthy humidity level throughout the year.

Ventsys window trickle vents can help you! Ventsys window vents can provide controlled and purified fresh air flow in your home. By installing Ventsys in each room, they can ensure continuous operation of the natural ventilation cycle, provided that the building’s exhaust ducts are not blocked and they operate as intended for buildings with the principles of natural ventilation.
