As well as temperature and air purity, another major factor in the maintenance of a healthy room atmosphere is the moisture content of the air. During winter months when rooms are heated, indoor air can dry out, sucking moisture from our skin, hair, mucous membranes in the throat and nose, furniture, plants, animals and anything else in the room.
Opening the windows will not help to avoid dry room air. Instead, it is necessary to actively add the correct amount of moisture to the air with a humidifier. Medical experts recommend a healthy relative air humidity of between 40-60 per cent for the home. At this level, the moisture content of the air will be in equilibrium at the temperature of the typical indoor environment.Effects of dry air in the homeDiscomfort, tiredness, sickness
- Breathing in dry air makes the uptake of oxygen and its subsequent transfer to the blood system more difficult. Fatigue, lethargy and reduced concentration levels are symptoms of a reduced oxygen supply.Increased susceptibility to colds
- The self-cleansing function of the windpipe is affected by dry air. The consequences: increased susceptibility to infections and respiratory tract complaints.Dry skin
- Low relative humidity results in greater loss of moisture from the skin's outer layers. It becomes dry, rough and flaky, and has a tendency to become inflamed.Increased levels of dust
- Humidity binds dust. Dry room air causes dust to rise. This is made worse by the thermal currents created by the radiators.Damage to hair
- Hair can easily dry out when heating systems are turned on making it more susceptible to damage like split-ends, less manageable and generally duller and less attractive.Increased static electricity
- A level of humidity below 40% will increase static build-up leading to uncomfortable sparks when touching metal objects.Damage to wooden objects
- Furniture and other wooden objects have a dull surface in dry room air. They dry out and eventually cracks will appear.Out of tune musical instruments
- Low moisture content in room air will cause musical instruments to go out of tune.Discomfort to pets
- Pets will suffer in the same way as humans, with dry skin and an increased susceptibility to infection. This will be worse in animals that are originally from a humid environment, like parrots, and they can become very ill in a dry environment.For a complete range of humidifiers for the home visit AirAndWaterCentre.com.
