What needs to be paid attention to, for the prevention of asthma in winter?

1. Preventing the feeling of cold

When the weather changes or becomes cold, more clothes should be added to prevent chills by the cold wind or by getting wet from rain or snow. Keeping warm around the neck area is especially important. Clothing should not be too tight, and one should wear smooth and soft pure cotton clothes. Mouth muffle-masks are needed when you go outside. For those who are not allergic to the influenza vaccine, an influenza vaccine may be injected.

2. Proper physical exercise

Asthma patients can do proper walking and deep breathing exercises. The patient lies flat on his/her back, with two hands overlapping on the umbilical region. After inhaling with nose, the patient exhales slowly with tight-lips, and the two hands press the abdomen lightly. When walking, the patient may halt and inhale deeply then go on walking and exhale slowly. Breathing with tight-lips means the patient inhales slowly with nose and then exhales with the mouth, and while exhaling, the mouth is shaped as if whistling. Exhaling should be completed and these actions should be done rhythmically. The exercise should last for 3 to 5 minutes and be repeated many times every day.

3. Maintaining health through diet

Food should be light and nutrition-rich, and the patient must not eat food that could lead to the onset of asthma. Eat less pungent and greasy foods and have more vegetables and fruits, such as turnips, sponge gourds and pears, bananas and loquats. Empty the bowels daily.

4. Calcium supply

Calcium has the function of resisting allergies. Asthma patients should have more calcium-rich food, but when eating sea-food or marine products, the patient should be careful of allergies.

5. Drink more water

It is very important for asthma patients to drink more water. Drinking water can not only supply hydration, but also dilute saliva.

6. Eating more meals but eating less food during each meal

Do not overeat or gorge yourself, and do not eat food that is too sweet or salty.

7. Training to cough and expectorate efficiently

Efficient coughing method: sit or stand with the front of the body tilting forwards, then breathe several times with the tight-lipped breathing method. After inhaling deeply, cough strongly while two hands press on the abdomen.

Efficient expectoration method: deep breathe then hold the breath, then cough twice for a short time and exert the body to expectorate sputum out of the lungs. The coughing time should not last too long, and this should be performed after getting up in the morning, or half an hour before a meal and before sleeping.
