How much influence does smog have on sensitive people and how to prevent it?
Studies have shown that increased incidence of allergies is closely related to air pollution. In smog, an increase in the concentration of PM2.5 in the air can cause various allergic diseases such as allergic rhinitis, asthma, eczema, erythema, itching, and diarrhea. So, how can sensitive people prevent allergies in the haze?
First, what is sensitive physique
Generally, people who are prone to allergic reactions and allergic diseases and cannot find the cause of the disease are called ‘sensitive physiques’. People with ‘sensitive physique’ can develop various allergic reactions and allergic diseases, such as allergic rhinitis, bronchial asthma, cough symptoms, itchy eyes or redness in the respiratory system; wind rash, eczema, angioedema, Red spots, itching phenomenon; digestive system may cause abdominal pain, nausea, vomiting, diarrhea, gastrointestinal bleeding, oropharyngeal itching, foreign body sensation and other discomfort.
Second, the cause of sensitive physique
The causes of sensitive physique can be divided into two categories, internal and external. The internal cause is mainly derived from the history of family allergic diseases, often caused by parents and lack of immune function of the body at birth; the external causes of sensitive physique are complex and diverse, mainly including food, drugs, cosmetics, chemicals, Pollen, pets, bacteria, air pollution, etc.
Third, the cause of the disease caused by sensitive constitution
The latest research shows that the formation of sensitive physique, as well as the onset of allergies, are related to the ‘healthy killer’ in the body – excessive accumulation of free radicals. The number of free radicals in allergic people is much higher than that of non-allergic people. Increasingly serious environmental pollution, chemical abuse and radiation problems will directly cause the accumulation of free radicals in the body.
Free radicals come from two sources: one is constantly produced in the body’s own oxidative metabolism; the other is environmental pollution, radiation, bad habits, etc., and will continue to generate free radicals. Free radicals can be called the source of all evils. The aging of the human body and the production of many diseases are closely related to it.
Free radicals form lipid peroxides that can damage biofilms, destroy cells, impede normal metabolism, accelerate aging, and cause such imbalances, allergies, refractory dermatitis, rhinitis, conjunctivitis, asthma, eczema, and myocardial infarction , gout, nephritis, cataracts and other diseases.
Fourth, the impact of air pollution on sensitive physical groups
Among many external factors, allergic diseases caused by air pollution account for a considerable proportion. Many studies have shown that increased incidence of allergies is closely related to air pollution. Increased concentrations of ozone and nitrogen oxides in the air can cause bronchoconstriction and decreased lung function, leading to allergic respiratory diseases such as allergic rhinitis and bronchial asthma.
PM2.5 is like a carrier that carries many harmful substances, such as bacteria, dust, heavy metals, etc., and when it enters the human body through the respiratory tract, the free radicals in the body will increase dramatically. Under normal circumstances, amino acids, vitamins and enzymes in the body can remove excess free radicals. However, in the case of high concentration of smog for a long time, a large amount of particulate matter is absorbed by the body, and free radicals in the body are increased, which cannot be removed in time, and will directly oxidize the human body. The mast cells and basophils cause the cell membrane to rupture and release histamine, which produces an allergic reaction. Therefore, improving the allergy will eliminate free radicals.
Pregnant women living in areas with severe air pollution for a long time are prone to low birth weight. Low birth weight is associated with a series of serious health problems, including postpartum imperfections, low immunity, heart and respiratory diseases, etc. One of the causes of allergies.
Five, how to prevent allergies
1.Go out wearing a mask
People with sensitive physique should wear masks when they go out, especially in foggy weather. You should choose a professional PM2.5 protective mask to minimize the crowds and plants and flowers to avoid contact with allergens.
2.The daily diet should be balanced
People with allergic physique should pay special attention to diet, try to eat less processed or refined, greasy, spicy food, and eat less sweets, these foods may aggravate allergic symptoms. Eat more foods containing vitamins A and C, which can scavenge free radicals and enhance the body’s immunity. Cabbage and citrus can resist allergies and should be eaten in daily life. Eat more calorie foods, you must not eat cold food.
3.To have good living habits
Wash your face and brush your teeth with hot water and change your laundry frequently. Keep the room clean, bedding and bed sheets should be washed frequently. Reduce outdoor activity time in the spring to prevent allergies to pollen. It is not advisable to keep pets and avoid contact with allergens from everyday life.
4.Exercise, enhance resistance
The living should be regular, do some physical exercise, relax and avoid emotional stress. Combined with the medicated diet to enhance immunity, it has a significant effect on improving allergic constitution.
