Sunburn is a form of radiation burn that affects living tissue, such as skin, that results from an overexposure to ultraviolet (UV) radiation, usually from the Sun.Common symptoms in humans and other animals include red or reddish skin that is hot to the touch or painful, general fatigue, and mild dizziness.
The most common type of radiation burn is a sunburn caused by UV radiation. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns. As the ionizing radiation interacts with cells within the body—damaging them—the body responds to this damage, typically resulting in erythema —that is ...
What causes sunburn in the first place? Ultraviolet rays from the sun come in two harmful varieties. Ultraviolet A (UVA) rays are so-called aging rays, which can lead to skin cancer and cause ...
The mechanism for sunburn and increased melanogenesis is identical. [14] Both are caused by the direct DNA damage (formation of CPDs). produces Vitamin D in human skin. is reduced by virtually all sunscreens in accordance with their SPF. is thought, but not proven, to cause the formation of moles and some types of skin cancer.
A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ionizing radiation (such as sunburn, caused by ultraviolet radiation). [5] [9] Most burns are due to heat from hot liquids (called scalding), solids, or fire. [10] Burns occur mainly in the home or the workplace.
The AAD recommends using a broad-spectrum sunscreen — meaning it protects against both UVA rays (which prematurely age skin) and UVB rays (which cause sunburn) — with SPF 30 or higher.

Sunburn effect (as measured by the UV index) is the product of the sunlight power spectrum (radiation intensity) and the erythemal action spectrum (skin sensitivity) across the range of UV wavelengths. [9] [10] The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the Earth's surface.
