Hives, Eczema, and UV Allergy: Causes of Itchy Red Bumps on the Body

The appearance of itchy red bumps on the body may be caused by hives, eczema, or UV allergy. Here's a breakdown of the possible reasons and care tips:

1. Causes of Itchy Red Bumps on the Body

1.1 Hives: Hives can cause red bumps on the skin, accompanied by sudden redness, itching, and various shapes of rashes. As the condition worsens, the rashes may gradually expand and merge into larger patches. These symptoms usually resolve within 24 hours but may be followed by the appearance of new rashes.

1.2 Eczema: Abnormalities in the body can lead to the development of eczema. Red bumps associated with eczema may be accompanied by swelling, erosion, and even weeping. The symptoms of eczema are often distributed on the limbs but can also occur on the face or trunk.

1.3 UV Allergy: Some individuals may be allergic to ultraviolet (UV) radiation. Exposure to sunlight for 1-2 hours can trigger the appearance of red bumps, commonly on the face, neck, and upper limbs. These bumps are usually painless but may cause intense itching and take longer to resolve.

2. Care Tips for Itchy Red Bumps on the Body

2.1 Dietary Considerations: Certain foods, such as seafood and lamb, may be irritating to the skin and should be avoided. It is important to maintain a balanced and healthy diet, avoiding greasy and spicy foods that may exacerbate skin conditions.

2.2 Personal Hygiene: It is crucial to maintain good personal hygiene when experiencing itchy red bumps. Regularly change and wash clothing and bedding to keep the living environment clean and hygienic. Additionally, avoid scratching the affected areas as it may irritate the skin and worsen the condition.
