When exposed to UV rays released from the sun, the skin produces melanin, a substance that protects us from the sun and gives our skin its color. However, when we come in contact with too many UV rays (hello, beach bums), the body can't produce enough melanin to protect the skin. It normally takes a few hours for a sunburn to actually become visible, so we may be in the red even before the burn even appears. But it goes beyond red skin and weird tan lines. In some cases, blisters can form, and the skin may even swell — a condition called edema. In more severe situations, sunburn can turn into sun poisoning, which can cause fevers, chills, and nausea.
