First of all, the symptoms of smoke hazards
The harm of smog to health is obvious, and people's respiratory system bears the brunt. The fine particles contained in smog are carriers of pollutants and toxic substances, and they are very small and can enter bronchi and even lungs through the respiratory system. Generally speaking, the diseases caused by smog are mainly concentrated in diseases such as nasal inflammation, respiratory diseases, cardiovascular and cerebrovascular diseases.
1. Nasal inflammation
In foggy days, the concentration of dust and dust mites in the air is relatively high, the activity of germs is enhanced, harmful substances and bacteria carried by fine particles are increased, and sensitive noses are very susceptible to infection with bacteria. When harmful substances are inhaled beyond the load, rhinitis will come unexpectedly, and persistent runny nose and cold will follow.
2. Respiratory diseases
The respiratory system is in closest contact with the external environment. In foggy days, hundreds of atmospheric particles can directly enter the upper and lower respiratory tract and lung lobes of human body, causing infection to the respiratory system, easily causing diseases such as bronchitis and asthma, and even serious lung infections such as pneumonia.
3. cardiovascular diseases
When the foggy weather is depressed and the oxygen content in the air drops, people tend to feel chest tightness, shortness of breath and rapid heartbeat. In addition, harmful substances carried in smog will hinder normal blood circulation, and particulate pollutants may also cause myocardial ischemia or injury. The United States investigated 25,000 people with heart disease or bad heart, and found that with the increase of PM2.5, the mortality rate of patients would increase 10 μ g/m3.
Second, solve the defense problem.
After knowing the harm of smog, how should we deal with it in our daily life in order to minimize the harm of smog to our health? Some people think that reducing outdoor activities and closing doors and windows at home can resist smog, but is this really the case? On the one hand, gas, lampblack, smoking and other factors will produce PM2.5, and the room is a closed space, which makes it easier to accumulate PM2.5; On the other hand, closing doors and windows does not mean that air circulation is cut off, and people will carry all kinds of particles when they go out and go home. Therefore, the smog in the home space can not be ignored.
1. Use air purifier, intelligent aldehyde remover, etc.
Air purifier, also known as air purifier, can adsorb, decompose or transform various air pollutants, including PM2.5, dust, formaldehyde, bacteria and allergens. Using air purifier to purify indoor air is one of the internationally recognized methods to improve indoor air quality. When purchasing an air purifier, we mainly consider CADR (the ratio of providing clean air) and energy consumption.
2. Replace household items regularly.
Sofa cover and curtains are easy to accumulate dust in household articles, so they should be washed and changed frequently. In addition, wiping tables and chairs and mopping the floor with water to increase air humidity will help reduce the floating of fine particles in the air. Bedding kits in the bedroom space can also be wiped clean with wet towels to absorb fine dust in the air.
3. Correct window opening and ventilation
Closing windows in foggy days can certainly reduce the intrusion of particulate matter in outdoor air. However, long-term closed environment will lead to high indoor flying concentration, increased bacterial content and decreased oxygen content. So it is wrong to close the doors and windows for a long time in fog. The correct way should be to open the window in time for ventilation. As long as you avoid the morning and evening traffic peaks and dust caused by strong winds, open the window for ventilation 2-3 times a day under the condition of calm wind, and each time lasts for 20-40 minutes. If you are worried about heavy pollution, you can hang a wet towel near the window when you open the window to play the role of filtration and adsorption.
Third, solve the attack in an orderly manner.
Respond to the harm of smog, keep breathing healthy, and also actively improve immunity. Strengthening physical fitness, improving metabolic capacity and improving self-resistance are the most fundamental measures. So, what can be done in winter to protect health and prevent diseases and repel smog?
1. Indoor sports
Hazy days should reduce the time spent outdoors, but at the same time, we can't ignore the importance of exercise to our health. Then indoor sports is obviously a good choice.
Yoga: Put a yoga mat on the carpet in the living room and you can start exercising. Yoga can not only stretch limbs and accelerate metabolism, but also regulate breathing and control mind and emotions through physical exercise, thus achieving the unity of body and mind.
Skipping rope: Skipping rope is an aerobic exercise and a coordinated exercise of the whole body. Skipping rope is one of the most popular forms of exercise, which is beneficial to enhancing cardiopulmonary function and exercising limb flexibility.
Aerobic dance: aerobic dance is the most interesting and diverse indoor sport. Dance action should be aerobics, music and dance are closely combined, which can achieve the effect of pleasing body and mind during exercise.
Dumbbell: Dumbbell is a very cost-effective instrument, which is not only convenient to use, but also can be used for multiple purposes. As long as you turn the digital dial at the top of the dumbbell, you can choose six different weight levels for different people to exercise.
2. Qingfei Decoction
Although the harm of PM2.5 cannot be completely eliminated, a scientific diet can greatly reduce the adverse consequences caused by smog. Eating more foods that clear and moisten the lungs and vegetables and fruits with strong antioxidant capacity can help relieve respiratory symptoms such as cough. Sydney, tremella, lily, yam and other foods have certain effects of nourishing lung and kidney. Steaming a bowl of Qingfei Ziyin soup in winter can not only warm the heart and stomach, but also purify the toxins accumulated in the body to some extent.
3. Aerobic green plants
Make your home greener and less foggy, put a pot of green plants on the balcony and decorate your home! Fresh green plants can not only purify the air, but also decorate the room.
Cactus: It can effectively absorb carbon dioxide and release oxygen, and its vitality is generally stronger than other plants.
Green radish: This high-efficiency air purifier originated from the Mexican plateau, which can purify benzene, trichloroethylene and formaldehyde in the air at the same time.
Aloe vera: potted aloe vera is known as an expert in air purification, which can effectively absorb harmful substances such as formaldehyde, carbon dioxide, sulfur dioxide and carbon monoxide.
Asparagus: Asparagus and other plants have antibacterial ingredients. Putting a pot of asparagus in the room can remove bacteria and viruses from the air and bring you a fresh sense of smell.
Fourth, solve the problems one by one.
Young children:
Children's respiratory immunity is weaker than that of adults. Some adults are infected with bacteria outside, and are resisted by the adult's immune system, which will not cause them harm, but it is easy to infect children after taking them home. Therefore, when adults go home, they must pay attention to cleaning, washing their hands and changing clothes frequently to reduce the infiltration of foreign bacteria. In addition, due to the decrease of sunshine in foggy days, children's absorption of ultraviolet rays is insufficient, vitamin D production in the body is insufficient, and calcium absorption is greatly reduced, which may affect children's growth and development, so they can be given more seafood and fruits and vegetables to supplement vitamin D.
Pregnant women:
Polycyclic aromatic hydrocarbons (PAHs), the main pollutants in haze weather, can be transmitted to the fetus through the placenta, which seriously affects the IQ of the fetus. Therefore, expectant mothers who are pregnant in smoggy weather must pay attention to protective measures. First of all, try to reduce going out and transfer all kinds of sports and training indoors. You can choose walking, simple yoga and other gentle exercises to exercise. Wear a mask if you must go out. In addition, pregnant women who rest at home for a long time should also pay attention to their emotional health. Smog weather is gloomy and easy to cause people's irritability, especially pregnant expectant mothers. Pregnant women can find more other things to do, such as watching TV, listening to music, reading books and so on to relax and have fun.
Old man:
If children are the most injured people under smog, then the elderly are the high-risk groups of smog hazards. Older people have aging physical functions and relatively poor awareness of smog prevention, and are more vulnerable to smog than young people. Old people who like morning exercises should get rid of the habit of doing morning exercises in foggy days, because morning exercises are precisely the time when the fog is the biggest in a day, and it is very easy to damage the lung function of the old people at this time. In addition, the elderly spend a relatively long time at home, especially in the bedroom, so we should pay attention to the regular ventilation of the bedroom and the replacement of bedding, keep the indoor humidity, and create an excellent environment for the respiratory health of the elderly.
Bian Xiao has something to say: we can't completely reverse the harsh environmental conditions, but we can start from the dribs and drabs of life to fight against the smog in home life, and reduce the harm of smog by installing air purifiers and increasing environmental humidity; Through diet conditioning and exercise, improve the body's resistance to accumulation, down-to-earth and fight smog.
