A good indoor climate is
important for your health
and well-being

Depressed, uncomfortable or even allergic

Medical Scientists suspect that a variety of disorders may be due to a bad indoor climate. Just as there is evidence proving that a bad indoor climate can aggravate or trigger other sufferings. However, it is not possible to exclude the fact that there might be more than the indoor climate which cause the body to respond inexpedient. So even though the list of symptoms associated with bad indoor climate is long, these symptoms might be caused by entirely different things:

  • Fatigue
  • Concentration difficulties
  • Headache
  • Malaise
  • Irritated mucous membranes
  • Hay fever-like symptoms

Dust mites and mould, which thrives in humid air, can definitely play a part in the development of asthma and allergy.

Dust mites
Today up to 7% of the Danish population is allergic to dust mites, and the number of allergy sufferers is increasing. Dust mites are tiny, white animals with 8 legs, which subsist on hair and skin flakes from humans and animals.

It is not the amount of dust, which determines the amount of dust mites in a house. Actually, only 0.5 grams of skin flakes from one person is enough to feed thousands of dust mites for a whole year. We normally produce between 0.5 and 1 gram of skin flakes a day, so there is always enough food. The amount of dust mites depends entirely on the temperature and humidity in the house. The best living conditions for dust mites are 17-32 ° C with a humidity between 55 and 75% RH. If the humidity is around 45% RH dust mites dry out and die.

Allergy

Symptoms of dust mite allergy can be:

  • Asthma (e.g. cough, wheezy breathing, a weight on the chest)
  • Hay fever (e.g. stopped nose, running nose, sneezing and itching eyes)
  • Worsening of child eczema/atopic dermatitis

If you have these kinds of symptoms you should seek medical advice.

Mould fungus
Approximately 2-6% of the Danish population is allergic to mould fungus in the nature. But there are no numbers describing how many percent of the population is affected by the mould fungus which can be found inside our houses. Mould fungus grows in organic material in a house, when the humidity exceeds 75% RH. E.g. on wood, plasterboard, wallpaper, glue, paint and textiles. The mould fungus is visible in form of stains, mould, mildew or discoloration.

If the humidity is high enough, mould fungus can hide in the walls or in the roof construction. Building materials that have already been affected by mould fungus once is more easily attacked again. Actually, you ought to replace those materials or treat them with fungicide. In a good, dry indoor climate mould fungus never stands a chance to live inside.

Symptoms of mould fungus, which can occur even if you do not have allergies:

  • Headache
  • Concentration difficulties
  • Asthma (worsening of asthma)
  • Hayfever (worsening of hayfever)
  • Irritated mucous membranes

If you have these kinds of symptoms you should seek medical advice.
