Decoration allergy is more common in clinical practice, and common symptoms include sore eyes, itchy nose, hot and red skin, etc. The symptoms of renovation allergy are similar to the feeling of being blown by cold wind, i.e. itchy eyes, skin cut-like pain, or the patient’s eyes are normal before going to bed and swollen and itchy after waking up. These symptoms are most likely caused by renovation, especially the recent renovation or purchase of new furniture. It is recommended not to place plants in the bedroom, because they can compete with people for oxygen, and the pollen and debris of plants are prone to cause skin and respiratory allergies and other symptoms.
