The Effects of Dry Air
- Dry heater air causes dry mucous membranes. Bacteria and viruses cannot be trapped and the danger of infection, catching cold and of allergic respiratory disease increases.
- Breathing dry air is harder on the lungs and makes it more difficult for oxygen to enter the blood. Symptoms can include tiredness, headache and reduced concentration.
- Wood furniture, parquet floors and musical instruments can crack when exposed to dry air.
- The indoor air can contain millions of fine particles invisible to the naked eye. Dust also rises in dry air.
