In severe haze weather conditions, the first principle to reduce injuries is to avoid going out. If you have to go out, you must take personal protection. During continuous haze days, it is also necessary to choose the appropriate time to open windows for ventilation. If the windows are not opened for a long time, there will be no fresh air in the room, and the pollution will be aggravated.

Tip 1: Wearing a mask

Wearing a mask can provide an additional barrier to prevent the inhalation of harmful particles. After taking off the mask, wait until the inside is dry before folding it in half to prevent the moisture from breathing from causing the mask to breed bacteria.

Tip 2: Wear a hat and long clothing

Hair has a strong ability to absorb pollutants. Wearing a hat can reduce the hazard, avoid excessive exposure of the skin, and reduce the contact area with harmful air.

Tip 3: Breathe peacefully

Stay out for a short time, breathe calmly, and walk briskly; do not ride a bicycle, avoid rush hours with heavy traffic and roads with a lot of driving, and avoid inhaling more chemical components; wash your face, gargle, and clean your nasal cavity promptly when you enter the house, and remove all harmful substances on your body contamination residues.

Tip 4: Drink plenty of water

In terms of diet, drink more water to speed up the renewal of water in the body; eat more fresh vegetables and fruits, which can not only supplement various vitamins and inorganic salts, but also moisten the lungs and remove dryness, eliminate phlegm and cough, and strengthen the spleen and kidneys. Eat a balanced diet to ensure adequate nutritional intake.

Tip 5: Reduce going out

During haze days, the elderly, children, pregnant women and people susceptible to respiratory diseases should avoid going out as much as possible; patients with asthma and coronary heart disease need to carry medications with them if they want to go out. If the haze irritates the respiratory tract and causes throat discomfort, coughing, chest tightness, and other symptoms that persist, you need to go to the hospital for treatment.

Tip 6: Stop outdoor exercise

Outdoor exercise should be stopped during haze weather. Morning exercise in haze weather can cause not only respiratory diseases but also cardiovascular and cerebrovascular diseases. Especially in winter, cold weather can cause vasospasm, elevated blood pressure, and angina pectoris.

Tip 7: Try not to open windows

You should try not to open windows in hazy weather. If you need to open windows for ventilation, you should try to avoid the peak hours of morning and evening haze. You can open the windows a little for ventilation, and the time is preferably half an hour to an hour at a time. In terms of window opening time, noon is more suitable because the PM2.5 concentration at this time is relatively the lowest in the day.
