According to media reports, on September 2, some netizens broke the news that after a thunderstorm in Hohhot, local patients had cough, wheezing and wheezing symptoms, and the video of the hospital being overcrowded attracted the attention of netizens.
According to the staff of Hohhot Health and Wellness Committee, there are more patients with "thunderstorm asthma" in many hospitals in Hohhot, and there are more wormwood in Hohhot, so there will be more patients with allergic rhinitis and asthma in spring and autumn. Heavy rain led to an increase in pollen and an increase in patients. Not only in Hohhot, Inner Mongolia, but also in Taiyuan, Shanxi, recently, some netizens reported that after the rainstorm, they developed asthma after taking off their morning pants.
Literally, will lightning bless pollen and cause thunderstorms and asthma? Although they seem to have nothing in common, if they are blessed together, it is likely to cause asthma.
"Thunderstorm Asthma" is a special type of bronchial asthma, which refers to the acute attack or aggravation of bronchial asthma in thunderstorm weather or followed by it. It is characterized by a large-scale outbreak of asthma in some areas, with symptoms ranging from mild to severe, and severe cases can be life-threatening. Almost all thunderstorm asthma occurs at the peak of pollen.
In fact, the earliest report on thunderstorm asthma was 1983 from Birmingham, England, and the most serious thunderstorm asthma occurred in Melbourne in 20 16. * * * More than 8,500 people were treated and 8 people were killed.
Generally speaking, thunderstorm asthma occurs in pollen season. Thunderstorm weather will not only lead to the focus of asthma and chronic obstructive pulmonary disease, but also make ordinary people have asthma symptoms such as shortness of breath and wheezing. According to media reports, since August, the pollen concentration in Lvjian urban area of Hohhot has been rising continuously, higher than the same period last year, hitting a new high this year. Pollen mainly comes from Artemisia, followed by Chenopodiaceae.
According to the related literature, the cold air flow before thunderstorm can bring pollen or mold particles into the cloud, and the water ridge and lightning in the cloud footprint layer can make pollen particles burst and release smaller particles. After returning to the ground, pollen particles are very easy to enter the human respiratory tract because of their small size, leading to asthma. Moreover, the strong electric field generated by thunderstorm may enhance the sensitization of allergens released by pollen, which is more harmful to people.
Thunderstorm weather ushered in Hohhot, Inner Mongolia, which led to a sharp increase in patients with cough and asthma, and a sharp increase in emergency patients in hospitals, which was related to "thunderstorm asthma" caused by high pollen concentration after rain.
In real life, the factors that lead to cough developing into asthma are very complicated. In addition to the above reasons, harmful gases, bacterial infections and other factors can also cause asthma.
When harmful gas can stimulate respiratory tract, it is also an important factor to induce asthma. Such as environmental pollution, paint, plates, etc. It can stimulate the respiratory tract and easily lead to cough and asthma. At the same time, bacterial infection is also an important factor to induce asthma. Bacteria can not only cause inflammation in the body, but also induce allergic inflammation in the airway through indirect ways, leading to cough developing into asthma.
A common saying is to nip in the bud. In order to avoid and reduce asthma caused by cough, we should prevent and treat it from the source:
First, when a thunderstorm occurs, try to close the doors and windows and stay indoors to avoid "thunderstorm asthma"; Second, for asthma patients without basic diseases, if they have symptoms such as dyspnea, they should take loratadine and other drugs to treat allergies and asthma in time. If the symptoms are not relieved, see a doctor in time; Third, we should treat allergic reaction to pollen according to the trace of the main foot. Prevent the occurrence of allergic asthma, form tolerance to pollen allergens, and then realize "desensitization" to prevent cough from developing into asthma; The fourth is to avoid contact with harmful gases, such as detoxification and medical treatment in time after contact, to avoid causing cough to develop into asthma.
