Introduction

Ultraviolet allergy refers to an allergic reaction caused by sun exposure on exposed areas of the body such as the face and limbs. When exposed to sunlight, the skin may develop symptoms including redness, papules, and blisters. The longer the duration of UV exposure, the more severe the symptoms are considered to be. Additionally, these symptoms primarily occur in areas exposed to strong sunlight, and are also more likely to develop in high-altitude regions with intense ultraviolet radiation.

Prolonged exposure to ultraviolet (UV) radiation can cause a certain degree of skin burns. In summer, sunlight contains strong UV rays, and if you spend extended periods outdoors without sun protection, the risk of skin damage increases significantly. Some individuals have sensitive skin, and excessive UV exposure may trigger allergic reactions. What are the symptoms of UV allergy?

What Are the Symptoms of UV Allergy?

UV allergy refers to an allergic reaction caused by sun exposure on exposed areas such as the face and limbs. When exposed to sunlight, the skin may develop redness (erythema), papules, blisters, and other symptoms. The longer the duration of UV exposure, the more severe the symptoms tend to be. These symptoms primarily occur in areas exposed to intense sunlight and are also common in high-altitude regions with stronger UV radiation.

When experiencing UV allergy, preventive measures are key. Practice daily sun protection and wear protective gear when going outdoors. Sunscreen should be applied to exposed areas such as the face and limbs. Additionally, pay attention to your diet—avoid phototoxic foods such as cilantro, celery, and lettuce, and steer clear of spicy or irritating foods that could worsen allergic symptoms. For localized outbreaks, topical applications like heat masks or ointments are commonly used. In cases of severe itching, corticosteroid creams may be applied.

In daily life, it's important to take proper protective measures to avoid prolonged exposure to sunlight. We hope this information is helpful to you. Wishing you good health and happiness!

Is coughing up phlegm after each nucleic acid test due to an allergy to the throat swab?

During throat swab collection, the swab may rub against the pharyngeal mucosa, causing mild irritation and increased mucosal secretions, which can lead to coughing with sputum. This condition is usually temporary and resolves spontaneously within 1–2 days without other discomfort. However, if coughing with sputum is accompanied by symptoms such as sore throat, redness, swelling, or itching, it may indicate an allergic reaction to the swab material or disinfectant used. Although such cases are uncommon, they require attention.

Can I eat pears if I'm allergic to the flu vaccine?

Allergic reactions to the influenza vaccine stem from immune responses to components such as proteins and adjuvants in the vaccine. Pears, however, mainly contain water, vitamins, and carbohydrates; their composition is mild and unlikely to cause cross-reactive allergies with the vaccine. Consuming pears in moderation during an allergic reaction can help replenish fluids to ease throat discomfort and provide essential nutrients, without adversely affecting recovery.
