    The prevention and treatment of indoor air pollution in our homes is essential to protect our health.

    To manage air quality in the home, you also need to monitor humidity levels.

    In fact, breathing air that is too humid or too dry can have harmful effects on our respiratory system.

    Humidity levels in the home can vary greatly between countries, continents and climatic zones. According to the WHO, between 10% and 50% of indoor environments in Europe, North America, Australia, India and Japan are not humid enough.

    The optimum level of humidity in the air is considered to be between 50% and 60%. Simple solutions exist to achieve this optimum level of humidity and so to preserve our comfort and health.

    • HEALTH IMPLICATIONS OF AIR THAT IS TOO DRY
      HEALTH IMPLICATIONS OF AIR THAT IS TOO DRY

      We consider the air too dry when relative humidity is below 30%. When the air is too dry and it comes into contact with the skin and mucous membranes, it seeks to re-humidify and 'capture' the water.

      Breathing air that is too dry on a daily basis can lead to skin dryness, eczema and dermatitis (redness of the skin) as well as dry eyes or conjunctivitis.

      Air that is too dry can also indirectly promote the development of chronic respiratory infections such as rhinitis, rhinopharyngitis or laryngitis.

      In children, air that is too dry will irritate the mucous membranes and increase respiratory difficulty, and so can promote the development of bronchiolitis.

      HEALTH IMPLICATIONS OF AIR THAT IS TOO HUMID

      We consider the air too humid when relative humidity is above 70%.

      Air that is too humid is associated with the proliferation of micro-organisms such as mold and acarids, the suspension of allergenic particles and also the release of numerous chemical pollutants into the air.

      These different pollutants, as they penetrate the respiratory system, can lead to chronic infections and the progressive deterioration of the respiratory mucous membranes with consequences such as :
      - acute respiratory diseases, bronchitis, bronchiolitis - chronic sinusitis and rhinitis.

      They can aggravate the mucous membrane in the eyes (conjunctivitis, damage to the surface of the eye). Breathing air that is too humid can also aggravate the symptoms of asthma.
