Do you wake up in the morning with a dry throat, headache, or just feeling unrefreshed?
This may be because the air quality in your bedroom is poor, either due to pollutants or lack of humidity.
The great importance of healthy humidity in indoor spaces is often underestimated. Relative humidity should be between 40% and 60%. We at AIRY often visit customers on site and conduct various measurements of the four important factors for air quality (CO2, VOC, particles, and humidity). It is extremely rare for this recommended and advisable value to be reached. Most measurements show values below 30%.
And that is a problem because:
-
Too low humidity dries out your mucous membranes in the respiratory tract, which can cause irritation, coughing, and even breathing problems. People with asthma or other respiratory diseases may be more affected.
-
Dry air draws moisture from the skin, which can lead to dry skin, itching, cracking, and flaking. People with sensitive skin or skin conditions like eczema may be more affected.
-
Too low humidity in the bedroom can cause dry airways and an uncomfortable feeling in the throat, which can disrupt sleep. This can lead to sleep problems and poor sleep quality.
-
Dry air can impair the protective function of the mucous membranes in the respiratory tract, increasing the risk of infections, especially respiratory infections.
-
Dry air can also cause irritated, dry eyes. People who already suffer from dry eyes may be more affected by low humidity.
- Too low humidity can keep dust and other particles suspended in the air longer, which can worsen allergy symptoms.
The AIRY System is (also) an innovative technology for regulating indoor humidity.
Three factors are responsible for this:
- The open water tank ensures rapid evaporation and circulation of water, if needed.
- Plants release the vast majority (over 90%) of the water they absorb back into the environment.
- The design of the AIRY System promotes natural air circulation in the room.
In January 2020, the renowned company M.TEC Engineering conducted a study measuring the effectiveness of the AIRY System L on the level of relative humidity in a 30 square meter room with furniture and people. It showed that using the AIRY System L in a dry room can increase the relative humidity level by up to 10% during the first 24 hours.
