Cough caused by cold is caused by virus infection. Generally, it can heal itself within 7 days, usually accompanied by sore throat and runny nose. In severe cases, there will be systemic symptoms such as fever, headache and muscle aches. Allergic cough is generally not accompanied by systemic symptoms, but is caused by allergens, such as allergies to cold air, pollen and mites. Symptoms are as follows: cough lasts for more than 4 weeks, often at night and/or in the early morning, mainly dry cough; It often happens when hot and cold alternate or seasons alternate; Cough recurs, and it is more severe and paroxysmal; There are no signs of infection in clinic, or long-term antibiotic treatment is ineffective.
How to control allergic cough in winter?
1, away from allergens. It is best not to lay carpets, use down bedding or store items with pungent smell in the bedroom of patients with allergic cough. Wash the window bedding frequently to prevent mites and their secretions from causing allergic cough again. If there is no sun for a long time in winter, it is best to soak in hot water for more than 20 minutes before cleaning. Indoor cleaning, it is best to use a vacuum cleaner or wipe with a wet cloth. People who are allergic to animal fur should avoid keeping pets, and people who are allergic to pollen should not put flowers indoors.
2. Etiology treatment. Allergic cough usually occurs in people with allergic constitution, which is related to genes and usually caused by heredity. Most children with asthma in allergic cough have a family history of allergies, but in recent years, due to the acceleration of industrialization and the aggravation of air pollution, some people who were not allergic have also evolved into allergic constitutions.
At present, the treatment of allergic cough in children mostly adopts long-term use of Shunerning to control the symptoms of allergic cough asthma in respiratory tract, and also cooperates with inhalation of glucocorticoid. However, because these treatments only treat the symptoms, they are not suitable for long-term inhalation, and the treatment really relies too much on the control of anti-allergic drugs and cannot be stopped. As long as the drug is stopped, it will recur or aggravate the cough and cause asthma. Failure to cooperate with immunotherapy or radical measures is also an important reason why many children with asthma rely on inhaled sex hormones for a long time and cannot stop taking drugs or drugs. In this regard, the International Immunotherapy or Radical Measures for Children's Allergic Asthma claims that when allergic diseases occur, such as allergic eczema, urticaria, children's recurrent allergic rhinitis, recurrent allergic cough and asthma, etc., the number of TH 1 cells will decrease due to the immune response in the human body. Under the stimulation of allergens, various cytokines such as IgE and eosinophilia are continuously produced, which promotes the immune response to TH2 pathway and forms humoral immune response. Children with asthma can supplement the active antiallergic probiotic composition-Xinminkang Probiotics, which can participate in the regulation of immune cytokines. This rare probiotic with antiallergic activity can promote the secretion of interferon in vivo to regulate TH 1 immune response and resist immunoglobulin IgE. By enhancing the TH 1 immune response of immune cells to regulate TH2 immune response which is overreacted due to allergy, children's anti-allergic ability can be improved. This safe intervention of Xinmin Kang probiotic antiallergic immunity in regulation therapy can greatly reduce or shorten the course of treatment of antiallergic western medicine, and regulate immunity to reduce allergy.
Cold in winter, children cough repeatedly? Doctor: Watch out for allergic cough.
3. Keep warm and moisturized. Pay attention to climate change when going out, and add warm clothes in time when it is cold, especially when it is windward, so as to reduce the stimulation of cold air on respiratory mucosa, keep the humidity of respiratory tract and prevent diseases such as colds. Maintain the temperature and humidity of indoor air. Excessive use of heating and air conditioning will lead to dry breathing and weakened mucosal epithelial resistance. It is best to use a humidifier to keep the indoor humidity appropriate. In order to keep the indoor air fresh, pay attention to window ventilation every day.
4. Increase outdoor activities. Ultraviolet rays have desensitization effect, and patients with allergic cough often bask in the sun in winter, which is helpful to relieve their illness. The best time for outdoor activities is 8~ 10 in the morning and 4~5 in the afternoon. Outdoor activities can be combined with jogging, cycling and aerobic exercise. After exercise, the blood circulation of the whole body will be accelerated, and the edema of respiratory mucosa caused by allergies will be significantly improved.
5. Eat healthily. The daily diet should be light. First, eat less spicy and greasy food, which is easy to stimulate respiratory mucosa. Secondly, after allergen testing, if it is confirmed that eggs, milk, shrimp, crabs and seafood are allergic, the intake of such foods should be avoided. Eat more fresh fruits and vegetables. Vegetables, fruits and grains rich in B vitamins, vitamin C and carotene, and foods rich in vitamin E, such as nuts and wheat germ, can effectively alleviate allergies.
