Supported by statistics and medical studies:

.Respiratory Discomfort

• Problem: Dry air can irritate respiratory passages, exacerbating conditions like allergies and colds.
• Evidence: Humidified air can relieve discomfort from colds and the flu, and help people who suffer from asthma.
  

Snoring and Sleep Issues

• Problem: Dry air can dry out the throat and nasal passages, leading to snoring or disturbed sleep.
• Evidence: While specific statistics are limited, maintaining optimal humidity levels is recommended to reduce snoring and improve sleep quality.
  

Static Electricity

• Problem: Low humidity increases static electricity, causing discomfort and potential damage to electronic devices.
• Evidence: Maintaining indoor humidity levels between 30% to 50% can reduce static electricity issues.
  

Damage to Furniture and Wooden Items

• Problem: Dry air can cause wood to crack or warp, damaging furniture and musical instruments.
• Evidence: Proper humidity levels help preserve wooden items by preventing shrinkage and cracking.
  

Plant Health

• Problem: Indoor plants may suffer in low humidity, leading to dry, browning leaves.
• Evidence: Maintaining appropriate humidity levels supports plant health, especially for tropical species.
  

Cold and Flu Symptoms

• Problem: Dry air can exacerbate symptoms like coughing and sore throat.
• Evidence: Humidified air can relieve the discomfort of colds and the flu, and help people who suffer from asthma.
  

Eye Irritation

• Problem: Dry air can cause dry, itchy, or irritated eyes.
• Evidence: Increasing indoor humidity can alleviate eye dryness. A cRCT showed a significant decrease in dry eye symptoms among working adults (OR 0.54, 95% CI 0.37 to 0.79).
