The salt and ice challenge is an internet phenomenon wherein participants pour salt on their bodies, usually on the arm and ice is then placed on the salt. This causes a "burning" sensation, and participants vie to withstand the pain for the longest time. The challenge can be recorded and posted on YouTube or other forms of social media. The salt causes the ice to lower its freezing temperature, and in the process absorbs heat from the environment (including the participant's hand) as it melts. As a result, skin temperature drops far more than with ice alone, even though the temperature of the ice is the same.

The process can quickly cause second and third-degree injuries similar to frostbite. Due to the numbing sensation of the cold and possible nerve damage during the stunt, participants are often unaware of the extent of any injuries sustained during the challenge. Skin discoloration from the challenge may remain after the challenge has been attempted.
