Mold and dust mites thrive in high humidity. However, overly dry indoor air can also negatively impact our well-being in various ways. Skin and respiratory organs are affected, making infections, allergies, and asthma more likely. Studies have shown that a relative humidity of 40 to 60% in indoor air minimizes pathogens and, consequently, respiratory diseases.
Pets, plants, and delicate items also require the right climate. Hygroscopic materials like wood, paper, leather, and textiles react to fluctuations in humidity. In high humidity, they absorb moisture, causing items to warp or develop mold. If the surrounding air is too dry, moisture is drawn out of stored goods. Musical instruments, wooden floors, frames, furniture, books, and carpets become brittle and develop cracks.
