Talk about the shortcomings of spring

Some people keep sneezing on their skin, and some people have itchy eyes' asthma'. According to doctors and experts, this may be caused by allergies. Spring is the season of high incidence of allergies. If you want to stay away from allergic symptoms, you must first understand some knowledge about allergies. Allergic dermatoses include solar dermatitis, pollinosis, insect bite dermatitis and so on. It is caused by factors such as sunlight, ultraviolet rays, pollen insect bites and waste gas. Many people think that ultraviolet rays will only harm people in summer. In fact, many people will encounter this serious situation in spring, because people's skin becomes thinner after winter care and has poor resistance to ultraviolet rays. Pure sunshine is warm in the sun, but ultraviolet rays will still irritate the skin and cause solar dermatitis. Sun protection in spring is also very important. Solar dermatitis is mainly characterized by redness and itching of exposed parts such as face and hands; Measles is also characterized by sudden itching of the skin, followed by flat wheal-like rash blocks of different sizes, so it is also called wind diagnosis block. Some rashes may be pale, and some may be red all over. If it occurs in the throat mucosa, it may be life-threatening. Allergens of allergic asthma caused by allergic asthma mainly include pollen, dust mites, germs and climate. Flowers that unexpectedly open in spring produce warm pollen, which is suitable for the growth of mites. They are all the reasons that lead to allergies suffering from asthma this season. In addition, due to the unstable climate in spring and the large temperature difference between day and night, some people are allergic to the cold and hot stimulation of the air, which can also induce asthma attacks. Allergic snuff is a happy season for many patients with allergic rhinitis. Repeated sneezing, runny nose, stuffy nose, can't help but hurt my nose. The unstable temperature and abundant pollen are also the main sources of rhinitis in spring. Seasonal allergic rhinitis is easily mixed with colds. Rhinitis, sneezing and runny nose are all symptoms of a cold. In fact, this is an allergic reaction on the surface of nasal mucosa. Food Allergy In addition to the above-mentioned contact allergies such as pollen and ultraviolet rays, many people are allergic to certain foods in their daily lives. For example, some people are allergic to protein in eggs, fish and shrimp, while others are allergic to prawns. Monopterus albus and other foods containing histamine are allergic, and some people are allergic to foods containing daily photosensitive substances such as snails, gray vegetables, rapeseed and safflower. There are many foods that are easy to cause allergies, and their manifestations are different. Some people will have fever, dizziness, nausea, vomiting and other symptoms immediately after eating allergic food, leading to bronchial asthma and dyspnea. Some people will have symptoms of gastroenteritis such as drunkenness, abdominal pain and diarrhea. So it won't appear after eating it. Don't judge food poisoning easily, because it is probably an allergic reaction to food, and food allergy is said to cause different degrees of heart damage, so we must pay special attention. From the perspective of traditional Chinese medicine, allergic constitution should also prevent contact with the head meat of animals. In the early days of hot springs, you should eat less nuts and spicy food such as peanuts and melon seeds to avoid getting angry, and eat more soup, porridge and some nourishing food, such as jujube, which can be adopted or recommended ~
