Illness Susceptibility

• When indoor humidity falls lower than 30 percent, people develop dry noses and throats, which makes them more susceptible to upper respiratory ailments.
  
  

Respiratory Relief

• Humidifiers also provide relief to people who have respiratory illnesses because moist air helps clear sinuses and stuffy noses, as well as bronchial symptoms.
  
  

Dry Skin

• Additionally, moister air prevents skin from becoming too dry.
  
  

Static Electricity

• Humidifiers are used to reduce static electricity, so people and pets do not receive shocks from touching objects or each other. Static electricity also can cause poor performance in computers and sensitive electronics.
  
  

Wood Issues

• Low humidity can cause shrinking and cracking of wood in the home, and furniture joints can become loose.
