"Have you ever heard of WiFi allergy?" asked Wu Mian.


    "..." Taoist Lin said nothing.


    In modern society, WiFi signals are everywhere, especially at home. You can''t live without WiFi. Even the old Gua mountain should have a signal, otherwise the people waiting in line to go up the mountain will spend their boring time.


    "Why? Little martial uncle, are you kidding? What you just said is that you can''t live without WiFi." Taoist Lin asked.


    "No, WiFi allergy is different from the so-called Internet addiction," Wu Mian said with certainty.


    "What''s that?"


    "Some people show allergic symptoms to all kinds of household appliances, mobile phones and other communication equipment, and even WiFi and other equipment emitting electromagnetic signals, including headache, dizziness, weakness and fatigue, skin allergy, arrhythmia and other symptoms.


    The World Health Organization defines it as electromagnetic radiation allergy, or EHS for short, "Wu Mian explained to Taoist Lin.


    "Er, you can''t use all the electrical appliances?" Taoist Lin was stunned. It sounded worse than water allergy. We can''t use all kinds of modern electrical appliances. Isn''t that about equal to primitive people?


    A while ago, the WiFi signal on the mountain was a little bad, which almost caused a big event, resulting in Shangxiang pilgrims falling off the cliff.


    In modern society, people... At least most young people in China have been inseparable from ubiquitous network coverage.


    "Almost."


    "Isn''t that similar to primitive people?" Taoist Lin asked.


    "They try very hard to find a comfortable place to live, but in modern society, electromagnetic wave transmission equipment such as mobile phones, computers, household appliances and signal bases make electromagnetic waves everywhere." Wu Mian sighed gently, "this world is hell for them."


    "I saw a patient in the literature who tried to get rid of all artificial radiation caused by WiFi. For this reason, he spent ￡ 1000 to build the room into a fully insulated Faraday cage."


    Put yourself in a cage? Taoist Lin began to imagine this picture. The picture is so beautiful and strange. Little martial uncle, do you still have research on shaking m? Great!


    "Don''t think blindly. You''ll know what you think is not serious by looking at your eyes." Wu Mian scolded.


    "Hey, hey."


    "The so-called Ferrari cage is made of insulating shielding materials such as tin foil, which is pasted on the roof, walls and ground in a large area. When he goes to bed at night, he must sleep in a customized silver plated sleeping bag to have a sense of security to isolate the electromagnetic field and sleep safely."


    "The machine in the patient''s Ferrari cage detects the radiation content and the reading is close to zero. Until this time, he can get a moment of breathing."


    "That''s too painful," Taoist Lin said.


    "In 2012, a violinist in Britain felt so bad because of this symptom that he had to end the pain by ending his life," said Wu Mian. "However, I studied many medical records and preferred that it was a psychological disease."


    "Er..."


    "The patient I just mentioned didn''t have the symptoms of electromagnetic wave allergy when he was a child," Wu Mian said. "Looking back on his medical history, when he was 16 years old, he went to the performance site of a famous band. The musician suddenly took out a special pistol and made a sound towards the ceiling as a live effect.


    But from that roar, the patient began a long and painful life of being allergic to electromagnetic waves. "


    "There are also several patients who have a clear medical history, that is, the inducement. Some are family quarrels and break the TV; some are municipal maintenance and install wireless signal system. When they suddenly see it, they feel that there are wireless signals in their body."


    "..." Taoist Lin couldn''t answer a word.


    Then they returned to the back yard.


    Chu Zhixi is reading a book, quietly. Hearing that the door was pushed open, she looked up and saw Wu Mian coming in wearing a Taoist robe with a smile and eyes like silk.


    "There are also patients who are allergic to clothes and quilts." Wu Mian went to the bamboo chair, touched Chu Zhixi''s head, smiled and lay in the bamboo chair.


    "Well... How do they live?"


    "A man named sybal Baman in India has been living without clothes since he was 5 years old because he was allergic to clothes. He is 43 years old this year.


    Every time he touches clothes, fabrics and other textiles, his body will feel tingling. Even at night, he can''t cover himself with a blanket to keep warm. "Wu Mian said," that''s in India. If you try our northeast, you''ll be frozen to death. "


    "Eh? Why do you say that you are allergic?" Chu Zhixi asked.


    "I just saw a female patient who was allergic to her boyfriend''s saliva," Wu Mian said.


    "It''s rare," Chu Zhixi said. "In 2009, our Union Medical College Hospital found a potentially fatal case of running after eating noodles. I was stunned when I saw it. Eating noodles is OK, but vigorous exercise is OK."


    "Er, is there such a situation?" Taoist Lin asked in surprise.


    Eating noodles allergy means that the patient is allergic to some substance in the noodles, which is conceivable. But it''s okay to eat noodles, but it''s okay to take strenuous exercise... It''s like installing an insurance. If this kind of case is clearly diagnosed, it''s quite difficult.


    "The case mentioned by the girl is also called food dependent exercise-induced allergic reaction. That is, within 6 hours after eating pasta, exercise can induce severe allergic reaction symptoms and even shock, but strangely, if you don''t exercise during this period, there will be no allergic reaction."


    "I''ll go!"


    "The diagnosis took two years, and many experts of Concord participated in the diagnosis and differential diagnosis of this difficult and miscellaneous disease."


    "Little martial uncle, did you join?"


    "I didn''t graduate at that time." Wu Mian glanced at Taoist Lin and said, "Lao Lin, the girl said something about 2009."


    "Little martial uncle, how do you remember these strange things?"


    "I''ll remember it after reading it, and it''s useful for the differential diagnosis of many diseases," Wu Mian said. "There are many difficult and miscellaneous diseases misdiagnosed in our grass-roots hospitals, such as patients who are allergic to strenuous exercise after eating noodles."


    "But this..."


    "Well, it''s not a problem that grass-roots hospitals can solve." Wu Mian smiled. "The reason why it''s a grass-roots hospital is that it doesn''t require to solve these things. If you find something wrong, you can send it to a superior hospital."


    "How are patients with saliva allergy?" Taoist Lin asked.


    "Not much, but there are more patients with WiFi allergy, clothing allergy and even color allergy," said Wu Mian. "JY allergy is common, about 8.5 per 10000."


    Taoist Lin smacks his tongue, ten thousand... Is this a common thing?


    But I''ve seen it. Write it down. I can ask more in case I encounter it in the future. It is estimated that he will still have the opportunity to see one or two similar patients in his life.
