"Have you checked all the allergens?" Li Zheng asked.

"We've checked everything and found no clear allergens," said Wu Mingyuan.

Li Zheng keenly grasped the key information in his previous words and said, "Director, your wife has only recently been experiencing frequent allergies? Hasn't this happened before?"

Wu Mingyuan nodded and said, "It only appeared in the last six months. I never had any allergies before. I was not allergic to anything I ate, went for a walk in the park, got injections or took medicine."

"Have you moved? Has your living environment changed significantly?" Director Tang analyzed with a frown.

Wu Mingyuan shook his head. "We've always lived in the County Health Bureau's staff compound, and the environment hasn't changed much in the past ten years."

"Have you eaten anything you haven't eaten before recently?" Director Tang continued to ask.

Wu Mingyuan still shook his head and said, "We eat breakfast and lunch in the cafeteria at work, and we usually cook at home. We don't eat anything weird, it's all home-cooked food."

That's strange.

Everyone had no idea what to do.

Li Zheng frowned, trying hard to recall his past life experiences, and thought of a possibility.

"Director Wu, has your wife experienced any major stimulation recently?" Li Zheng asked.

Um?

No one understood what Li Zheng meant.

Is there any connection between irritation and allergies?

But Li Zheng must have his reasons for asking this.

Wu Mingyuan thought about it carefully, his eyes lit up, and he said, "It's true. Half a year ago, her mother was walking on the road and was hit by a truck. It was a tragic accident. She saw it and fainted immediately..."

Wu Mingyuan's voice grew louder as he spoke. "Since then, she's started to have frequent allergic reactions, but...why would she have an allergic reaction if she was stimulated?"

Li Zheng nodded and said, "She must have developed a stress-induced allergic reaction after being stimulated at that time."

"Stress allergy?" Wu Mingyuan looked confused.

The others also looked at Li Zheng in confusion.

Li Zheng nodded and said, "Stress allergy refers to allergic symptoms caused by an abnormal immune system reaction after the body is stimulated by various stressors. These stressors can be physical, such as infection, trauma, surgery, etc., or psychological, such as long-term mental stress, anxiety, depression, etc."

"This situation is extremely rare. Your spouse was affected by your mother's car accident and has been in a mentally abnormal state for a long time. Therefore, he is easily susceptible to external stimuli, which can cause an overactive immune system."

After listening to Li Zheng's explanation, everyone felt suddenly enlightened.

"Li Zheng, your knowledge reserves are so rich!" Director Tang gave a thumbs up unconsciously.

Dean Zhang nodded repeatedly with satisfaction. As long as he could perform so well in front of Director Wu, he would not be afraid of not getting the equipment.

Wu Mingyuan frowned again and said, "That's still a bit hard to explain. Her allergic reactions are usually mild, just a rash on her body, and it heals quickly. But why is it so severe this time?"

Li Zheng thought for a moment and said, "Under what circumstances does she usually have allergic reactions?"

Wu Mingyuan shook his head and said, "We don't know either. They just appeared out of nowhere."

"Have you ever changed your living environment?" Li Zheng asked again.

Wu Mingyuan nodded and said, "She also stayed at her daughter's house for a while, and she felt more relaxed, but she still had allergies from time to time, and she was very distressed."

Now everyone was confused again.

This doesn't make sense again.

"Did she feel any special stimulation today?" Li Zheng asked.

Wu Mingyuan shook his head and said, "It wasn't anything particularly exciting. There was a fire at a house across from our compound. Two fire trucks came and quickly put out the fire. She stood by the window and watched for a while. I didn't see anything unusual about her mood, but after that, she became unwell. Then a rash broke out like crazy, and she felt really uncomfortable. So I rushed her here."

"Did the fire stimulate her?" Director Tang asked.

Wu Mingyuan shook his head and said, "It shouldn't be. The fire wasn't big, and no one was injured. She was very calm after seeing it. After all, my mother-in-law died in a car accident, so a fire shouldn't have shocked her."

Everyone looked at Li Zheng, hoping that he could find the key.

Li Zheng nodded and said, "Your wife probably has color allergy, which is a rarer type of stress allergy."

"What? Color allergy?"

Now everyone was even more dumbfounded.

"Is there anyone else who is allergic to colors?" Director Tang asked in disbelief.

Others had the same idea.

Li Zheng nodded and said, "Color hypersensitivity is an extremely rare psychological or physiological abnormality. Patients experience allergic symptoms to specific colors, such as red and yellow. This may involve psychological factors, such as traumatic associations, or rare physiological sensitivities. Your spouse probably developed a traumatic association with the color red after your mother's car accident, which triggered the allergic reaction."

Everyone nodded repeatedly. This explanation seemed to make more and more sense.

Li Zheng continued, "Ever since the car accident, she's had an allergic reaction to the color red. It was mild, so she might not even be aware of it. She might just have a slight aversion or fear of red. But today, with the arrival of two fire trucks and the flashing red lights, the sheer amount of red in such a short period of time triggered a severe allergic reaction."

"That's right!" Wu Mingyuan slapped his thigh. He finally found the answer to the problem that had troubled him for a long time.

Dean Zhang and Director Tang also nodded.

"Haha, Li Zheng, your explanation is so reasonable!" Dean Zhang laughed and said, "I didn't expect people to be allergic to colors. I'm really impressed!"

"Then how should it be treated?" Wu Mingyuan asked anxiously.

Li Zheng thought for a moment and said, "Your wife is suffering from psychological allergies and needs psychological treatment."

"First, use cognitive behavioral therapy. Communicate more with your loved one to help her re-establish a neutral perception of color and gradually desensitize her. Second, use exposure therapy, which involves slowly exposing her to red in a safe environment. Start with a light red and gradually deepen and increase the color to reduce her fear response."

Wu Mingyuan nodded continuously, keeping Li Zheng's words in mind.

"At present, as long as your loved one does not have excessive exposure to red, he or she will not have a severe allergic reaction. You can temporarily stop taking anti-anxiety drugs. After a period of treatment, he or she should be completely desensitized." Li Zheng added.

"Okay, okay, thank you so much, Dr. Li. Please take care of the treatment. My wife asked her to stay in the hospital for a few more days. She will listen to you more."

Director Tang quickly stated, "That's no problem. As long as your spouse is willing, they can stay until they fully recover."

Wu Mingyuan smiled and shook his head, "Given her impatience, it would be great if she could stay here peacefully for three days."

"Why don't we go to the internal medicine intensive care unit? It's more convenient there," suggested Dean Zhang.
