What does sunburning mean?
“Sunburning” names the process by which excessive ultraviolet radiation damages the skin, producing redness, tenderness, warmth, and sometimes peeling. It can be used as a verb, especially in progressive constructions such as “His shoulders are sunburning,” and as an adjective before a noun, as in “sunburning skin.” The term is common in everyday English but is not a formal medical diagnosis. British speakers often use “sunburnt” and American speakers often use “sunburned” for the resulting condition, while “sunburning” focuses more often on the process or describes skin that is actively affected. Although people commonly associate sunburn with heat, ultraviolet radiation is the primary cause of the skin injury. A sunburn can therefore occur even in cool weather or through reflected or artificial UV exposure.
To develop sunburn after excessive exposure to ultraviolet radiation.
"Her arms were sunburning by the end of the hike."
Most often used in the progressive form. This form is less common than “getting sunburned” or “getting sunburnt” in some varieties.
Red, tender, painful, or peeling because of excessive ultraviolet exposure.
"She covered her sunburning cheeks with cool compresses."
Common before nouns such as “skin,” “face,” “nose,” and “arms.” The alternatives “sunburnt” and “sunburned” are often more idiomatic when describing a person.
A sunburn is mainly a warning from ultraviolet radiation: the heat may feel intense, but the skin damage is caused primarily by the sun’s UV rays.

Where does sunburning come from?
“Sunburning” is a modern participial form of the English compound “sunburn,” formed from “sun” and “burn.” “Burn” comes from Old English “burnan” and ultimately from Proto-Germanic, while “sun” is also Germanic in origin and reflects Proto-Germanic *sunno-*. The compound had become established by the nineteenth century, and the addition of “-ing” allows it to describe the process of developing a sunburn as well as skin affected by one.
