15 Unexpected Twists Your Body Takes With Diuretics
6. Skin Sensitivity To Sunlight

Diuretics—especially thiazide types—can increase sensitivity to sunlight, a condition known as photosensitivity. Patients may experience skin rashes, burning, or peeling after minimal sun exposure. Some may even develop a sunburn-like reaction despite using sunscreen. To reduce risk, it’s recommended to wear long sleeves, hats, and broad-spectrum SPF 30+ sunscreen when outdoors. If severe reactions occur, patients should speak with their doctor, who may adjust the medication or dosage. Regular skin checks and sun-avoidance strategies are especially important during summer months or in high UV regions.
