Importance of controlling air humidity in buildings

You need a good relative humidity
Humidity can have a direct impact on the health, comfort, well-being and performance. The target level of humidity in buildings is typically between 40-60%. Humidity levels also key for building constructions, materials and equipment in buildings. The need of controlling humidity is essential in all buildings such as schools, offices, homes, hospitals, etc.
Drink water (six to eight glasses a day) and keep the relative humidity above 30%.
