Ideal Relative Humidity for Bedrooms
The ideal relative humidity for bedrooms for optimal sleep is generally between 40% to 60%.
What happens if humidity is too high?
High humidity in a bedroom prevents your sweat from evaporating, making you feel sticky and hot, which disrupts your sleep cycle. It also encourages the growth of dust mites and mold, exacerbating allergies and asthma.
What happens if humidity is too low?
Dry air (below 30%) can dry out your nasal passages and throat, leading to a scratchy throat, dry skin, snoring, and a higher susceptibility to respiratory infections.
