How do indoor plants help with room temperature and humidity?
Indoor plants help **increase and maintain relative humidity** through the natural processes of **transpiration** and the **evaporation of moisture from pot soil**. Studies have shown that rooms containing plants consistently exhibit **higher relative humidity levels** compared to plant-free environments. This increase in humidity is beneficial as it can **speed up the settlement of dust** and reduce the concentration of airborne particles. Regarding thermal conditions, research indicates that **room temperatures are generally lower** in spaces where houseplants are present. For instance, one study observed that mean room temperatures were **consistently higher when plants were absent** compared to when they were placed inside. By providing **adequate control of temperature and humidity**, plants contribute to a more comfortable indoor environment. This natural maintenance can potentially **reduce the reliance on energy-intensive climate control methods**. Certain species, such as the **Boston Fern**, are specifically highlighted for their effectiveness in increasing humidity in buildings.
