Humidity in the house: how to measure the humidity in the home and establish the ideal levels. Causes and natural remedies for humidity in domestic walls.

L'humidity in the house it is perhaps the worst problem to fight, a difficult condition it entails consequences for walls and to the building as a whole.

Humidity in the house, damage and health consequences

Colds, conjunctivitis, cough and stuffy nose are just some examples of consequences that thehumidity in the house can have on man. In the most critical situations, humidity can get to trigger real asthma attacks.

The World Health Organization itself has repeatedly stressed how much to live in humid environments and unhealthy can seriously affect your health. Tracheitis, rheumatism and arthritis are the order of the day if you live in a very humid house. It is mainly the respiratory system that suffers: according to the latest analyzes carried out, those who live in damp or moldy buildings have a 75% more chance of having respiratory disorders such as asthma, rhinitis and allergies.

Moisture and mold in the house

In our homes, mold can form mainly due to water infiltration, poor ventilation of the rooms or the absence of adequate sun exposure. Mold, caused by humidity, is decidedly unsightly, smelly and is bad for our body.

Humidity in the house, causes

The causes of its appearance are many: bad atmospheric conditions, condensation that is created in environments such as bathrooms or kitchens, leaks caused by breakage of the water pipes, rising damp, which mainly affects the floors that rest on the ground.

Umidness in the house that dates back to the ground

To prevent soil moisture, it is necessary to insulate the external wall in contact with the ground with waterproof materials. There are waterproofing plasters, plastics, aluminum sheets, membranes or bituminous paints: it should be emphasized that these materials should be used only in the necessary points.

Waterproof barriers must also be built consisting of draining crawl spaces, consisting of pipes and crushed stone under and around the house.

Moisture in the walls of the house, building remedies

To restore the walls subject to humidity, we can resort to an ad hoc intervention which consists of cutting the masonry horizontally and then inserting a mechanical barrier made up of different materials such as cement mortar or bituminous sheath.

Alternatively, we can intervene by injecting water-repellent material based on silicone and the like.

Another effective remedy is to insert specific siphons in the walls for the collection and evaporation of moisture.

Another technique used in construction is to insert electrodes to exploit the principle of electosmosis. In this case, a polarity inversion will occur between the negative pole of the subsoil and the positive pole of the wall to be restored, thus obtaining an inversion in the direction of migration of the water.

Humidity in the house, natural remedies

To reduce the humidity in the house, there are some domestic measures that we can adopt

  • Facilitate the ventilation of the rooms.
  • Install home dehumidifiers.
  • Keep the windows open every morning for at least 10 minutes, trying if possible to create drafts.
  • As an alternative to dehumidifiers, put quicklime in a large basin: it absorbs atmospheric moisture.
  • Do not let very wet clothes dry on the clothesline in the house and wet the indoor plants, avoiding the water stagnating in the saucers.
  • Install a fan in the bathroom while in the kitchen remember to turn on the extractor hood.

How to measure the humidity in the home

On Amazon you can find a tool called Hygrometer or Hygrometer Thermometer. There are models with the most disparate prices, starting from 10 euros for occasional measurements up to several hundred euros for high-precision models that allow constant measurements.

The Bresser 7007400 model is a hygrometer with ventilation recommendation, capable of detecting both internal and external humidity. In fact, an external sensor will be supplied. The device for measuring humidity in the home can be bought for € 30.69 and free shipping.

The indicated hygrometer offers constant monitoring of humidity but on Amazon it is also possible to buy instruments that offer a one-off measurement at a cost of less than 10 euros. Choose the product that best suits your needs.

For all information, please refer to the official Amazon page: Bresser, hygrometer with ventilation indicator.

Ideal humidity levels in the home

In general, in a house where the temperature is around 20-22 degrees, the ideal humidity rate should be around 40-60%. But it must never drop below 20%, otherwise the air would be too dry.

Humidity and condensation in the house

Do not confuse condensation and humidity!
Condensation is formed by the encounter between a cold surface and hot air which, cooling down, releases steam in the form of droplets.

A trick to distinguish condensation from humidity? Just dry the wet area with the hair dryer and cover it with a piece of glass. If after a few days you find the humidity on the glass, on the side of the room, it is condensation, if instead the humidity forms on the side of the wall it is humidity coming from the outside.
