Dry nose, cracked itchy skin, and sore throats are just some of the many side effects of living in an environment that is low in humidity. New research from the Oregon Department of Health Services has also demonstrated that the right levels of humidity can reduce and prevent against harmful bacteria and respiratory infections. Optimal humidity levels for good health are between 40% and 60%.
In cold seasons when heating systems dry the internal atmosphere the air can often drop below 40% relative humidity (RH). At this level it will draw moisture from any available source.
This includes our bodies, materials such as wood and textiles, our pets and even the fabric of our home itself. This will not just leave us feeling dehydrated but can have serious implications for our health.
Illness - The transmission of airborne viruses, such as influenza, is significantly reduced at a humidity above 40% RH. Also, the mucous in our nose and throat is our body's natural defence against airborne pollutants. When it dries our immune system is weakened.
