The "Salt and Ice Challenge" is a risky activity where participants place salt on their skin and then press an ice cube against it. The combination of salt and ice creates a rapid drop in temperature, which can lead to frostbite or severe skin burns. This challenge gained popularity through social media, particularly among teenagers seeking thrills. Despite its appeal, the challenge poses significant health risks. Medical professionals warn against participating, as the potential for injury is high. It is important to prioritize safety and avoid engaging in activities that can cause harm to oneself or others, especially those promoted online.
