In Singapore, aircons are frequently used to cool the home and office to create a comfortable and conducive environment for work and living. While it resolves the heat issue, do you know that it takes away the moisture in the air when it cools the room (i.e. air is blown against cold surface to create cold air and this leads to condensation and removal of moisture in the air)? Do you know your skin and health may be affected when the humidity falls below a particular level (i.e. air becomes too dry)?
When the air is too dry, our bodies are deprived of the necessary moisture to function properly. When the skin is dry, it becomes rough, scaly or flaky and triggers itchiness. Our natural response to itchiness is to scratch the skin and this leads to cuts and sores. In addition to dry and itchy skin, low humidity may also cause dryness in throat and nose passage and leads to sore throat, nose congestion, nose bleed, eye discomfort and cracked lips.
How can you restore the air moisture to prevent the above mentioned health conditions from low humidity level? The most primitive way of introducing moisture into an aircon room is to place bowls of water and wet towels. However, the bowls of water and wet towels may not increase the level of humidity level as fast as a humidifier. The humidifier is a more effective way of restoring the air moisture in the aircon room. However, you should ensure that you choose a humidifier with the right capacity based on the size of the room.
Humidity level should be kept at between 35 and 50 percent. If the humidity falls below 35 percent, it suggests that the level of humidity is too low and may cause some health issues as mentioned in the earlier paragraphs. A hygrometer measures the humidity level and you can easily buy it to measure the humidity level.
