Is the humidifier really harmful to health?
In fact, the humidifier itself is good for health. In winter, the indoor humidity is low. When the humidity is lower than 20%, the human skin and respiratory tract will be uncomfortable, and symptoms such as nosebleeds and itching may occur. The American Academy of Pediatrics (AAP) also recommends using a humidifier when the baby has a cold or a dry nose, which can make the baby more comfortable.
