Children and teenagers perceive this practice as a game to be played among friends, and sometimes, alone. The practice consists on stopping the flow of oxygen to the brain, leading to fainting, and sometimes, a total loss of consciousness. The goal of the game is to achieve a stage of euphoria before passing out. These games vary in its ways to be executed, often proposed as a challenge through videos on the internet and among friends in a group. Children and teenagers perceive these games as safe, not knowing the risks involved due to a lack of public information and awareness about the severe consequences, specially if practiced alone.
