A week after one mum took to social media to warn parents about the deadly "fire bending" craze, which left her son with second-degree burns, comes news that yet another dangerous viral trend has resurfaced among teens.
The salt and ice challenge involves placing ice and salt on the skin, resulting in an effect similar to frostbite. It can cause second and even third-degree burns as well as permanent nerve damage.
As part of the challenge, kids compete to see who can withstand the pain for the longest, posting photos of their burns and scars to social media.
Speaking anonymously to Hull Daily Mail, one mum shared that her son had been treated in a burns unit after taking part in the viral craze. And now she's warning parents to be vigilant on social media.
"The consultant said he had never seen an ice cube do this much damage," she said.
"[My son] has absolutely no feeling on the burn at all. It is so deep that it has burnt all the nerve endings. He has some feeling in the red part around the edge but nothing on the burn itself.
"It is like severe frost bite. It could have gone septic and caused organ failure.
"He is looking a bit sheepish now."
The National Society For the Prevention of Cruelty to Children (NSPCC) in the United Kingdom has also issued a warning to parents following the resurgence of the dangerous viral craze.
"The rise of social media has contributed to increasing peer pressure amongst children," the NSPCC told The Huffington Post UK. This 'craze' is another clear example of the risks.
"It is important for schools keep a close eye on all emerging trends and we welcome the warning to parents."
