Plants Keep Office Dwellers Healthy

When the air is too dry, people are susceptible to colds and flu.  When the humidity is too high, people can develop other ailments.  Through their natural processes of transpiration and evaporation, office plants add moisture to the dry, over-heated air often found in sealed office environments.  At the same time, studies show that plants do not add moisture in significant amounts when the air is already moist. 

A study conducted at Washington State University, suggests that plants help regulate humidity.  When plants were added to an office environment, the relative humidity stabilized within the recommended “healthy” range of 30 to 60%.
