Relative Humidity: How it Affects Your Living


When the relative humidity in the room is below 30%, a different type of health risk arises. You can experience skin irritation, dry eyes, decreased resistance to diseases of the upper respiratory tract. Low humidity may also discourage pests (such as cockroaches) and dust mites.

Low Humidity effects

A low humidity environment can cause dry eyes and nose symptoms and make your throat dry and itchy. When the mouth, nose, and throat mucous membrane dries, it is more difficult for the body to get rid of the bacteria that cause the flu or upper respiratory tract infection. Your skin becomes dry too, and wrinkles appear.

High Humidity effects

High humidity is when your home is stuffy and uncomfortable. Excess moisture causes condensation, which is an ideal situation for mold growth. Some molds release mycotoxins into the air, which can cause allergies or neurological harm. Typically, affected areas include walls, window frames, and insulation.

A humidity level above 55% can activate mold growth, although the ideal moisture level will be 70% or more. A humidity level above 55% can trigger mold growth, although the perfect moisture level will be 70% or more.

Humidity or dampness (water vapor) in the air can supply enough moisture for mold growth

You can not get rid of mold by simply wiping it with a wet sponge or using chemical products. Mold continues to appear over and over after cleaning. As in many things, what is needed is not a quick fix but a work with the source.
But you can change the climate of your home. Check the humidity room level where mold appeared. Ventilate the room to reduce possible spread if a mold source is found.

Health symptoms

Irritated eyes, headaches, difficulty breathing, chronic coughing and sneezing, irritation to the throat and nose mucus membranes, and impaired concentration.

To prevent a humid moldy-bacterial environment

  • Open windows to provide cross ventilation and reduce moisture and odors that commonly arise from cooking and bathing.
  • Change furnace filters regularly
