1. Allergic reactions: Mice may carry various allergens, such as dandruff, proteins in urine, saliva, etc. When the human body comes into contact with these allergens, it may cause allergic reactions, leading to symptoms such as itching and redness of the skin.
2. Bacterial or fungal infections: Mice may carry various bacteria, fungi, or parasites, which may remain in bedding. After human contact, it is easy to be infected, causing skin discomfort such as itching, rash, etc.
3. Psychological factors: In addition to actual physiological reasons, psychological factors may also cause itching on the body. Knowing that a bed has been crawled by mice, people may experience anxiety due to concerns about hygiene, which can sometimes be perceived by the body as discomfort or itching.
