Physical Symptoms

• Dry skin, sinus irritation, burning eyes and excessive thirst all point to overly dry air inside buildings. In the winter, the heating equipment dries the air, just as the air conditioning does in the summer. Dry skin cracks and leads to infections. Sinuses also become irritated, which eventually leads to sinus headaches. Dehydration causes discomfort and results in urinary problems.
  
  

Office Equipment

• Paper jams in office copiers and printers indicate that the humidity levels are too low. Laser copiers and printers use high heat to bond the toner to paper, which dries the paper even further. When the equipment jams or does not operate properly, companies and organizations lose productivity and waste paper.
  
  

Static Electricity

• Shocks from static electricity may be annoying to people in offices, but these shocks cause equipment failure in machines that use low voltages, especially computers and sensitive electronics. The shocks have the potential to light highly flammable materials if the shock is strong enough. Some people use rubber mats under the computers or chairs to reduce the damage caused by electrical shocks.
  
  

Solutions

• Cold or warm spray humidifiers in an office increase the humidity levels and mitigate the problems caused by dry air. Mechanical humidifiers rest inside the ducts to add humidity to the air in large air conditioning systems. Using a humidity meter helps manage the moisture in the air at safe and comfortable levels. Living plants in offices also provide relief from dry air since these plants take in and release water vapor constantly.
