Pay attention to ventilation when using humidifier in winter

“The humidifier almost killed me.” kate ˙ Fante recently told reporters of the British daily mail about his experience.

One day in November, 17-year-old Kate ˙ Fante suddenly lost his breath. “I was sitting in the classroom, my throat was suddenly closed, my tongue began to swell, and I ran to the emergency room.” Kate recalled that a few minutes later, her arms and chest appeared honeycomb like swelling and erythema, with an increasing area. Fortunately, the medical staff arrived quickly and injected Kate with adrenaline, so that her symptoms were gradually controlled. On Kate’s way to the hospital by ambulance, medical staff also injected her with steroids urgently.

The doctor told Kate that it was an extreme allergic reaction. The body’s immune system is mobilized, releasing a large amount of histamine, a chemical that eventually causes tissue swelling. This is also the real culprit that led to her dyspnea, decreased blood pressure and even death.

What exactly was Kate attacked? Although she was allergic to pollen and some foods, Kate recalled that she had not been exposed to these allergens recently.

The terrible situation did not end. Kate found that as soon as she went to school, she would have the same allergic symptoms at least once a week. Every time she had allergies, she needed a week’s rest. Her academic performance plummeted and her attendance rate was as low as 60%.

Therefore, Kate was called “Kate allergic to school” by her classmates. She began to pay great attention to her diet, and resolutely refused to touch foods that would cause her allergy. But every time I go to school, I will soon get sick and be sent home.

However, Kate’s parents had to send her to London to find an allergy expert to help her find the real allergen. Finally, the doctor found that Kate was allergic to a kind of mold, which existed in old-fashioned window frames, furniture and buildings, as well as in some refrigerators, especially in poorly ventilated rooms. Kate said that the school building is really old, and they often have classes in a shed. Due to the weather, in order to keep warm, the teacher turned on the humidifier and radiator in the poorly ventilated classroom.

Doctors found that people who are allergic to this kind of mold will feel stuffy nose, itchy eyes, cough, asthma and eczema. George, a pediatric allergist at St. Thomas Hospital ˙ Dr. Du introduced that late autumn is a high incidence period of this kind of mold allergy. Humidifier brings humid environment, does not often open windows for ventilation, and condensation formation, which are all the reasons why it causes allergy. This kind of mold often appears in kitchens, bathrooms, moldy haystacks, storage rooms, garages, sheds and other places.

If the house is not well ventilated, these molds can cause serious lung infection and damage. Case, member of British Lung Foundation ˙ Dr. Prowse said they can also lead to lung scars, and even death in severe cases. In winter, when the indoor environment is very dry, many families turn on the humidifier. This requires cleaning the room from time to time, especially the bottom layer of potted plants, where this kind of mold gathers.
