Coffee is a "refreshing gift" for office workers and students, and household coffee machines have also become popular household appliances in recent years. However, some foreign studies have pointed out that the steam of the coffee machine makes it easy for bacteria to breed and, in serious cases, can cause disease. Some doctors pointed out that healthy people do not need to worry too much, but the chronically ill need to pay attention.

According to a research report published in the US journal Applied and Environmental Microbiology by a research team at the National School of Medicine of the University of Toulouse, France, steam emitted by coffee machines increases indoor humidity, creating a favorable environment for fungal growth, especially on walls and wallpaper.

The team studied toxins produced by several homegrown, different types of fungi, said David Denning, a professor of infectious diseases at the University of Manchester in the UK. studies have shown that these mycotoxins can be found in the air and are usually attached to dust. Mycotoxins can be absorbed by the human body, causing irritation to the eyes, nose, throat and lungs, and even causing headaches. The study also pointed out that these toxins may lead to sick building syndrome, that is, headache, eye discomfort, cough, asthma, tiredness and sensitive skin caused by indoor air pollution.

People with weak resistance should pay attention.

Ng Kin-cong, a respiratory specialist in Hong Kong, pointed out that although domestic coffee may emit high-temperature steam, it will not be conducive to fungal growth unless it is emitted for a long time in a sealed, high-temperature and high-humidity environment, such as a sauna. In general, in the home, the humidity will be adjusted and the air will dilute the steam. I believe it is not a big problem to use the coffee maker. "the coffee machine will not be open 24 hours a day." He believes that healthy people should not worry too much, but those with weak resistance should pay more attention to those who suffer from heart, lung, kidney, liver disease or diabetes. If you want to reduce the growth of bacteria in your home, you should maintain indoor ventilation.

Chen Niande, a family doctor, pointed out that as the weather in Hong Kong is relatively humid, members of the public should take corresponding measures when they return to the south. For example, he will regularly find a cleaning company to do mildew prevention work at home and turn on a dehumidifier in summer.
