A sunburn is redness and discomfort on your skin caused by too much sun exposure. It's like your skin is saying, "Whoa, slow down!"
When people talk about getting a sunburn, they usually mean that they stayed outside for too long without using sunscreen or a hat to protect themselves from the sun's strong rays. You might hear someone say, "I got a bad sunburn last weekend when I went hiking." Or, "I'm so sorry I forgot my sunscreen today, now I have a sunburn on my nose."
A burn on the skin caused by excess exposure to the sun's rays.
