Papular urticaria is a type of allergic reaction, mostly related to direct contact with irritants, or bites from mosquitoes and fleas. Therefore, it is essential to be cautious in daily life. Do not keep small animals at home, and if you do, ensure that they are kept clean, bathed frequently, and disinfected regularly. If you live in a humid environment, often sun and disinfect your bed sheets and covers. Avoid going to places with many mosquitoes and insects like under trees or grassy areas. Try to avoid spicy and irritating foods for a long time, do not stay up late, exercise more, bathe more frequently, and avoid soaking in public baths or swimming. Do not stay too long in unclean environments. Maintaining good personal hygiene is sufficient.
