n.
damage to the skin by excessive exposure to the sun's rays, principally UVB (ultraviolet B), at wavelengths of 290-320 nm. Sunburn may vary from reddening of the skin to the development of large painful fluid-filled blisters, which may cause shock if they cover a large area (see burn). Fair-skinned red-haired people are more susceptible to sunburn than others. Severe sunburn in childhood is a risk factor for the development of malignant melanoma in later life.
