Luodong weather forecast

This article is taken from the article number 4 17/ Guo Yuetan. The smog disaster struck, and the fog filled the distance, and the air quality was "purple explosion". The weather forecast warns people to close doors and windows indoors and wear masks when going out to avoid inhaling bad air and endangering their health.

Fetuses rely on umbilical cord for oxygen and nutrients to maintain life. Newborns come to this world and loudly declare that they can breathe on their own, which shows the necessity of air to the human body. Normal people breathe about 16 ~ 20 times per minute, and breathing frequency is too fast or too slow, which may indicate that the body is abnormal; Inhaling bad air for a long time will definitely endanger your health.

Inhaling harmful air will shorten life span.

Qiu, convener of public affairs of Taiwan Province Chest and Critical Care Medical Association, vice president of medical treatment and director of internal medicine of Luodong Pok Oi Hospital, said that air is inhaled through the nasal cavity, and the airflow passes through the upper respiratory tract such as the throat, enters the lower respiratory tract such as trachea, bronchus and lung, and exchanges gas with the blood delivered to the lung by the heart in the alveoli of the small airway of the lung, delivering oxygen to the blood for oxygenation and discharging carbon dioxide from the body, thus maintaining life.

To survive, people must have two vital signs, such as heartbeat and breathing, which correspond to the heart and lungs that support the operation of the human body. Among them, the heart is responsible for promoting blood circulation throughout the body, while the lung is an important organ for gas exchange, and air can be called the source of life.

If the lung inhales more harmful substances during gas exchange, it may cause lung injury in the long run, and then pulmonary fibrosis and even lung lesions will occur, which will affect the pulmonary ventilation function, lead to the decline of cardiopulmonary function and oxygenation capacity, and it is easy to feel breathless when breathing normally. Over time, the function of various organs in the whole body will gradually decline and the life span will be shortened.

What are the bad air?

Air pollutants can be roughly divided into indoor and outdoor. Common indoor air pollution sources include carbon monoxide (CO), nitric oxide (NO) and nitrogen dioxide (NO2) produced by the combustion of gas stoves, electric stoves and heaters. Volatile organic compounds, such as formaldehyde, produced by home decoration, furniture or the use of paints, pesticides, detergents and hairspray; And cooking fumes, smoking, human hair, cats and dogs, mold, dust mites and other organisms.

The main sources of outdoor air pollution are exhaust gas from factories, automobiles and locomotives, agricultural pesticides and fertilizers.

The air quality is poor, so wear a mask when you go out.

According to the monitoring data of each monitoring station, the Environmental Protection Bureau converts the concentrations of ozone (O3), fine suspended particulate matter (PM2.5), suspended particulate matter (PM 10), carbon monoxide (CO), sulfur dioxide (SO2) and nitrogen dioxide (NO2) into air quality index (AQI).

The AQI index is divided into six grades according to the impact on human health. The following is a detailed description of each grade.

◆ 1 grade (green): the air quality is good.

All ethnic groups can go out for activities.

◆ Grade II (yellow): The air quality is average.

Ordinary people can exercise outdoors normally, and extremely sensitive people may have cough or shortness of breath.

◆ Grade III (orange): The air quality is unhealthy for sensitive ethnic groups.

If people cough, have sore eyes or throat, they should reduce outdoor activities, but should reduce long-term strenuous exercise. It is recommended that patients with heart, respiratory and cardiovascular diseases, children and the elderly reduce physical exertion activities and outdoor activities, and wear masks when necessary.

◆ Grade 4 (red): The air quality is unhealthy for all ethnic groups.

It will affect everyone's health, and sensitive people may have more serious health effects. Ordinary people should avoid strenuous exercise for a long time Patients with heart, respiratory and cardiovascular diseases, children and the elderly are advised to stay indoors and wear masks if necessary.

Grade 5 (purple): The air quality is unhealthy.

Everyone can have serious health effects. Generally speaking, people should reduce outdoor activities. Patients with heart, respiratory and cardiovascular diseases, children and the elderly should stay indoors to reduce physical exertion. If necessary, they should wear masks when going out.

◆ Grade 6 (reddish brown): air quality is dangerous.

When a health threat reaches a state of emergency, everyone may be affected. In general, people should avoid outdoor activities, close doors and windows indoors and wear masks when necessary. Patients with heart, respiratory and cardiovascular diseases, children and the elderly should stay indoors, avoid physical exertion and wear masks when necessary.

Qiu suggested that people can look at distant mountains and buildings before going out. If the line of sight is blurred, it may mean that the concentration of suspended particles is too high, but the best way is to query AQI index. Take protective measures according to suggestions, especially for highly sensitive people such as infants, the elderly, pregnant women, and people with asthma, lung obstruction, cardiovascular diseases, etc., which are easy to induce the onset and deterioration of diseases. Pay special attention to your health.

Fine suspended particulate matter PM2.5 causes many diseases.

In recent years, fine suspended particulate matter PM2.5 has been regarded as an indicator pollutant and a first-class carcinogen by the United Nations World Health Organization. In fact, PM2.5 is a very fine suspended particle with a diameter of only 2.5 microns, which is too small to be seen by naked eyes, accounting for about 1 of hair and 1 of red blood cells. Inhalation into human body will seriously endanger health.

Qiu said that PM2.5 is very subtle, and it will go deep into the alveoli in the deepest part of the lung with the ventilation effect of the lung, and flow to various organs of the whole body through microvessels, which will first cause inflammation of microvessels of the whole lung, and then lead to chronic inflammatory reaction of the whole body, and then lead to the deterioration of the functions of various organs.

When the body is in a state of chronic inflammation for a long time, it will cause a variety of chronic diseases. Common diseases include allergy, asthma, lung obstruction and lung cancer. It can also cause damage to vascular endothelial cells and cause cardiovascular diseases such as hypertension, heart disease and stroke. At the same time, it will increase the risk of tuberculosis, diabetes, dementia and various cancers.

Air pollution and lung obstruction are the fourth leading causes of death.

Qiu stressed that the impact of air pollution on the lungs is the first. In the long run, it is easy to get lung obstruction. According to the statistics of the World Health Organization, about 3 million people worldwide die of lung obstruction every year, and it is predicted that it will become the fourth deadliest disease in the world by 2030.

Lung obstruction is a respiratory obstruction disease caused by chronic inflammation, and the common symptoms are asthma, cough, excessive phlegm and so on. When the lung function deteriorates gradually and breathing is difficult, it will be life-threatening, and the average life expectancy of patients will be reduced by 6 ~ 10 years. Qiu suggested that people can use the "1 minute climbing lung obstruction risk assessment scale". /kloc-climbing less than 30 steps per minute is a high risk, panting after climbing 50 steps is a medium risk, and climbing 80 steps is a low risk. It is best to diagnose and treat as soon as possible to avoid the continuous deterioration of the condition.

12 measures to prevent inhalation of bad air

Qiu believes that * * * should promote policies on air quality maintenance, and people should start by changing their habits. Everyone is an important and indispensable part of improving good air quality.

1. Strictly control the emission of factory waste gas: factory waste gas is the main source of air pollution.

2. Garbage reduction and garbage classification: Reducing garbage generation and garbage classification will help reduce air pollution.

3. Reduce the use of steam locomotives: take more public transport and ride bicycles to reduce the exhaust gas emitted by steam locomotives.

4. Avoid burning incense, paper and guns: burning will release a variety of harmful substances, replacing incense with incense.

5. Avoid smoking: The burning of cigarettes will produce hundreds of harmful substances.

6. Avoid using curtains and carpets: curtains and carpets are easy to accumulate dust and dust mites.

7. Use a vacuum cleaner: use a vacuum cleaner when cleaning to avoid raising dust and reduce the inhalation of indoor dust.

8. Dehumidifier: The climate in Taiwan Province Province is humid, so the use of dehumidifier can avoid mold breeding.

9. Use a range hood: When cooking food, remember to turn on the range hood to avoid inhaling harmful fumes.

10. Close the doors and windows: When the air quality is poor, close the doors and windows to prevent air pollutants from entering the room.

1 1. Wear a mask: just use a surgical mask. The mask provides 90% protection and should be replaced every day to avoid repeated use.

12. air purifier: effectively remove harmful substances in the air, provide high-quality indoor air quality, and remember to replace the filter regularly.

2 strokes to strengthen lung function

1 trick: eat more dark fruits and vegetables.

Brightly colored vegetables and fruits are rich in antioxidants and phytochemicals. Eating more dark fruits and vegetables in daily diet can reduce the oxidation and inflammatory reaction in the body and avoid cell damage, such as spinach, tomato, carrot, eggplant, broccoli, amaranth, pumpkin, sweet potato, taro, corn, pitaya, papaya, blueberry, red-heart guava, kiwi fruit, grapefruit and so on.

The second measure: deep breathing exercise

Exercise can increase vital capacity, strengthen lung, improve lung function and increase tolerance. According to the research report, Tai Ji Chuan, swimming, yoga and other aerobic exercises, through long-term deep breathing and breathing, can train respiratory muscles, achieve effective ventilation training, and directly and effectively improve lung function.
