It's okay to rest with someone who has urticaria, but some details should be noted to minimize discomfort or impact. It's recommended to keep the environment clean, avoid shared contact with items that may trigger the rash, and monitor the patient's health.

Specifically, the following aspects should be considered:

1. Understand the contagiousness of urticaria: Urticaria itself is not contagious. It is usually caused by allergies, infections or physical irritants, so daily contact such as sleeping in the same bed will generally not transmit the disease.
2. Pay attention to triggering factors: If the patient's urticaria is related to certain allergens, such as pet hair, dust mites, or certain skin care products, these substances should be avoided as much as possible when resting together, and the bedroom should be kept well-ventilated and the bedding clean.
3. Pay attention to the patient's symptoms: If the patient's rash is accompanied by severe itching, it may affect sleep quality. In this case, you can help adjust the room temperature or use loose and soft bedding to help relieve discomfort.
In summary, when resting together, the focus should be on creating a comfortable environment and avoiding allergy risks. If the patient experiences frequent or severe symptoms, it is recommended to seek medical advice promptly. Additionally, it is important to observe and record potential triggers in daily life to better manage the condition.
