Drying wet clothes in the home can increase the humidity of the room can be up to 30 percent and trigger the growth of mold, which is bad for the health.
According to experts from the Asthma Society of Ireland, it could affect people who are difficult breathing, asthma, a weakened immune system or skin problems. It also could have an effect on infants, children and the elderly.
"Humid environment triggers the growth of fungi that can release spores. Spores trigger allergic reactions for some people. The fungus and fungal spores are often invisible," said Pheena Keeny of Asthma Society of Ireland.
Pheena explain usually when people inhale the spores, the immune system will help him out through coughing and sneezing.
"If you are not sensitive to mold, you will not react. But for people who have asthma are sensitive to mold spores, it can be a trigger, making asthma symptoms worse," he said.
So, better drying clothes outdoors, or use the dryer. Avoid too wet laundry drying in the room or family area, regularly open windows to improve ventilation of the house.
An extractor fan is also another solution reduces the moisture in kitchens and bathrooms, as well as continue to clean the air conditioner to facilitate ventilation, as reported by The Sun.
