Prevent respiratory diseases in humid weather

Use a dehumidifier to dry the living space, wear warm clothes, and limit alcohol to help reduce the risk of respiratory diseases in humid weather.

On February 4, Hanoi continued to drizzle, with dense fog appearing in the early morning. High humidity during the day combined with gradually increasing temperatures after a series of cold days caused a humid phenomenon. According to the National Center for Hydro-Meteorological Forecasting, the humid phenomenon will last until February 8 (ie the 29th day of Tet).

Master, Doctor Le Thi Hong Tham, Department of Respiratory Medicine, Tam Anh General Hospital, Hanoi, said that prolonged humidity increases the risk of common respiratory diseases such as flu, sinusitis, laryngitis, bronchitis, pneumonia... Children, the elderly, people with underlying diseases or pregnant women are susceptible to disease due to poor resistance. People with underlying diseases such as chronic obstructive pulmonary disease (COPD) and asthma can develop dangerous acute episodes.

High humidity causes condensation in the house, causing mold, viruses, and bacteria to thrive. When the weather is humid, families often close their doors to prevent moisture from entering the house, causing poor air circulation and creating favorable conditions for microorganisms to grow and cause disease. The difference in temperature inside and outside the house combined with frequent weather changes makes it difficult for the body to adapt, making it more susceptible to disease.

On humid days, families can use a dehumidifier or turn on the air conditioner in dry mode to reduce humidity in the air. Humidity of about 40-60% is best. Floors, glass doors, and bathrooms are places where water easily accumulates, making them slippery and dangerous to move around in, so they should be wiped regularly with a dry, moisture-absorbing cloth.

Carpets have high moisture absorption properties, are susceptible to mold in humid weather, and can become a source of disease transmission. Families should limit the use of carpets at this time.

The weather changes constantly, with drizzle and fog in the morning, sunny at noon, and cold rain in the evening, making it difficult for the body to adapt. Doctor Tham recommends that people wear many layers when going out so that they can change their clothes appropriately. When moving, keep your nose, mouth, ears, neck, chest, and limbs warm to avoid these parts from getting cold. If your body gets wet in the rain, you need to quickly change into dry clothes and warm up by drinking warm water or ginger tea. The cold from wearing damp clothes can easily cause respiratory diseases.

Humid weather often occurs from February to April every year, coinciding with Tet, festivals, and many parties. People who consume a lot of alcoholic beverages such as wine and beer need to keep their bodies warm.

Dr. Tham explained that alcoholic drinks cause peripheral vasodilation, making us feel hotter, but in fact, it does not increase body temperature. In fact, dilated peripheral vasodilation causes the body to cool down. The feeling of "virtual" heat, along with increased heart rate and blood pressure after drinking alcohol, makes many people subjectively dress lightly. At this time, the body is exposed to cold air, making it susceptible to colds, pneumonia, and life-threatening strokes.

A nutritious diet, regular exercise, and vaccination against influenza, pneumococcus, and whooping cough help improve resistance and prevent disease. People with respiratory symptoms such as cough, runny nose, fever, sore throat, etc. should see a doctor for accurate diagnosis and treatment. Absolutely do not buy antibiotics or antipyretics on your own, and avoid reusing old prescriptions. People with chronic diseases should follow the doctor's instructions.
