Too much exposure to sunlight or UV light can lead to photodermatitis. Know the early warning signs and prevention tips.

Too much exposure to the summer heat can lead to inflammation in the skin. And when the skin is exposed to sunlight or ultraviolet or UVB light for a long time, it can lead to photodermatitis. In an interview with HT lifestyle, Dr Satish Bhatia, dermatologist, Indian Cancer Society, Mumbai said, “The skin can become sensitive to UV radiation due to a combination of internal sensitivity and environmental exposure. Although it triggers a more severe immune response to light, this condition is often mistaken for sunburn.”

Early warning signs of photodermatitis

“The symptoms of photodermatitis include redness of the skin, which can also appear flushed and irritated. A person may experience persistent itching in the affected areas of their body. In severe reactions, fluid-filled blisters and peeling may occur. You may experience puffiness or localised swelling, especially on the face, neck, or arms,” the dermatologist explained.

Allergic reactions, itchiness and respiratory symptoms are some of the other signs of photodermatitis. The early signs of the condition can appear within a few hours of being exposed to the triggers, added the doctor.
