Introduction
Sunburn refers to solar dermatitis, which may be caused by physiological factors such as sun exposure, or pathological factors such as allergies, photosensitive dermatitis, and polymorphic light eruption. It is recommended to seek medical attention promptly and receive appropriate treatment based on the underlying cause. Specific analysis is as follows: In daily life, one should ensure adequate rest, maintain sufficient sleep, and avoid staying up late.
Solar dermatitis refers to sun-induced skin inflammation. This condition may be caused by physiological factors such as exposure to sunlight, or by pathological factors including allergies, photodermatitis, and polymorphic light eruption. It is recommended to seek timely medical attention and receive appropriate treatment based on the underlying cause. The details are as follows:
1. Physiological Factors
If one is exposed to sunlight for prolonged periods, the skin may become irritated due to ultraviolet radiation, leading to solar dermatitis with symptoms such as redness, swelling, and a burning sensation. Wearing sun-protective clothing can help alleviate these effects, and it is important to avoid direct sunlight.
2. Pathological Factors
1) Allergies
Individuals with allergic constitutions may develop an allergic reaction upon exposure to allergens such as pollen or house dust mites, which can trigger solar dermatitis accompanied by symptoms like skin redness, swelling, and itching. Under medical guidance, patients may take antihistamines such as loratadine tablets, cetirizine hydrochloride tablets, or chlorpheniramine maleate tablets for treatment.
2) Photodermatitis
This condition may be related to sunlight exposure or long-term medication use, resulting in increased sensitivity of the skin to light, thereby inducing the aforementioned symptoms, including redness, swelling, and pain. As directed by a physician, topical treatments such as halometasone cream, mupirocin ointment, or fusidic acid cream may be used to help improve symptoms.
3) Polymorphic Light Eruption
Polymorphic light eruption may be caused by genetic predisposition or sunlight exposure. After sun exposure, affected areas of skin may develop rashes or blisters, potentially leading to solar dermatitis along with itching and pain. Under medical supervision, patients may use medications such as compound menthol camphor ointment, indomethacin-nitrofurazone tablets, or methylprednisolone tablets for treatment.
In daily life, individuals should ensure adequate rest and sufficient sleep, avoid staying up late, and engage appropriately in outdoor activities such as walking or calisthenics, which may aid in recovery.
