Why Humidify... For Nursing and Retirement Homes

Overview

Dry sinuses, dull hair, skin irritations and catching an influenza virus are common side effects of living or working in a low humidity environment. According to a published research conducted by theOregon State University, the right levels of humidity are proven to reduce and prevent harmful bacteria and respiratory infections from spreading. To achieve an optimal level of humidity to support health and comfort between 40% and 60% of room humidification are recommended. Particularly during the winter seasons while indoor heating dries room atmosphere the air humidity level is very likely to drop below the recommended minimum of 40% RH. A low humidity level like this causes a very dry indoor environment which will ultimately causes patients and inhabitants physical discomfort.

Airborne Infections

Dry air tends to find moisture sources in a room in anything possible, such as mucous membranes. Since these membranes function as the natural shield of a body, once they dry out we tend to be more vulnerable to colds, flus and viruses.

Dry Eyes and Sore Throat

Dry eyes and a sore throat are common initial signs of overexposure to dry air and can create an uncomfortable work environment for employees. Particularly people with a weak immune system are likely to experience health problems in a dry air office environment.

Dry Skin

A dry room forces the air to draw moisture from any possible other source, one being hair and skin which results in itchy skin and dull hair.

Illness

A humidity level of above 40%RH significantly decreases the spreading of any airborne viruses, such as influenza.

Static and Dust

The accumulation of static electricity is highly likely in an environment of humidity below 40%RH. That means that fragile electronic tools may suffer damages due to dust rising into the atmosphere. By keeping RH levels above the 40%RH mark, this possibility is significantly reduced.
