Clean air - healthy indoor climate

Humans spend at least two-thirds of their lifetime indoors. The quality of indoor air therefore plays an important role in our health. Dust, cigarette smoke, bacteria, odors - all of which severely affect the quality of the air. Then only generous ventilation helps.

The air in the rooms

Indoor air quality is given too little attention today. In doing so, it contributes significantly to increasing physical and mental performance as well as to a comfortable living environment. Clean air contains 78% nitrogen, 21% oxygen, 0.03% carbon dioxide and 0.93% noble gases.

This composition changes as soon as people, plants or objects are in a room or apartment. Humans release moisture and carbon dioxide into the indoor air. The oxygen content decreases as it is consumed by breathing. Airing has an impact on many things that make up a healthy climate!

humidity

The humidity determines in a special way, if you feel comfortable in a room. To low humidity dries out the mucous membranes, then, for example, bacteria and viruses can spread faster and cause a cold. Too high humidity is quickly felt as oppressive; it can arise if you air too rarely.

Not to be neglected are the amounts of water vapor that are released by residents in apartments. A person at rest sweats about 1 liter; an active person about 2.5 liters. A family of 4 people daily releases up to 10 liters of water as water vapor into the environment. This corresponds to a full bath per week! Optimal for a good room climate is a relative humidity between 40 and 60%.

molds

Mold spores are practically everywhere in the air. However, they need moisture to germinate. In poorly ventilated rooms, it quickly happens that the moisture from the air condenses on surfaces. If a place stays moist longer, it provides a breeding ground for mold. Conscious, prudent behavior can minimize the development of moisture. In the first place, there is the adequate, proper ventilation of the rooms: on dry walls, the fungal spores can not thrive!

Visible or hidden mold in apartments is under no circumstances to be accepted. Allergy sufferers can be additionally weakened by mold fungi, the quality of living also suffers from the unappetizing smell. For the removal of the molds must be searched for the cause for their emergence.

carbon dioxide

Already 130 years ago, German researcher Max Pettenkofer recognized the carbon dioxide content of air as a measure of indoor air quality. For the health of humans, the CO 2 content of the air is of great importance. Every day, every person breathes in and out around 24 kilograms or the equivalent of 20, 000 liters of air.

When the concentration of carbon dioxide in a room rises, we become tired and our concentration suffers. Increases the carbon dioxide content even further it comes to blurred vision, dizziness, central nervous dysfunction, headache and in the worst case death by internal suffocation.

Airing - The windows open several times a day!

It is really good to exchange the "bad" air for "good" four times a day. It would be ideal to exchange the room air completely even every two hours. In the morning after getting up, a good ventilation of the room is important because the person loses a lot of moisture during the night. Lunch and dinner should also be aired to reduce the carbon dioxide content of the air. For a good and healthy sleep, it is advisable to ventilate just before bedtime.

  • Ventilate regularly and several times a day, preferably for 3 minutes cross ventilation. This creates draft, which even renews the used air in niches and corners. In addition, then a short time is enough to completely exchange the air.
  • Short-term opening of the windows (bum ventilation, about 4 to 10 minutes) is another effective way to renew used air. By the way, this airing is much more productive than leaving a window open all day in tilted position. In addition to the loss of energy, mold can form due to the condensation of moist indoor air.
  • Humidifiers can be used to increase the indoor humidity during the cold season.

Recommendations under load

  • If you have a physical condition, consult your doctor.
  • Persistent inhalation of harmful substances can lead to health problems. For this reason, have an examination of the indoor air carried out to determine the source and then eliminate it.
  • When purchasing building materials, furniture and carpets, you should pay attention to the contents of the manufacturer and the eco-label.
