There are so many things out there that kids don’t realize are dangerous. With new videos popping up on YouTube and kids talking at school, it’s hard to keep up. The scary thing about this new social media challenge is that it seems harmless, but can send your child to the hospital.

The challenge is called “salt and ice challenge” and the craze has taken over YouTubers and social media users. This simple challenge calls for kids to place salt and ice together on their skin. However, the salt lowers the temperature of ice to as low as negative 17 degrees Celsius or 1.4 degrees Fahrenheit, and the effect on skin can be similar to frostbite. Unfortunately because of the numbness and redness from the ice, many kids aren’t realizing they may be giving themselves second-degree burns.

“It is important for schools to keep a close eye on all emerging trends and we welcome the warning to parents,” a NSPCC spokesperson told the Huffington Post UK. “The rise of social media has contributed to increasing peer pressure among children. This ‘craze’ [salt and ice challenge] is another clear example of the risks.”

If you’re worried that your child might take part, talk to them about the effects as well as peer pressure.
