What Are Blackout Challenge Videos
Blackout challenge videos are short clips showing people intentionally restricting oxygen to the brain to achieve a brief euphoric or unconscious state. Participants may use ligatures, pressure on the chest, or hyperventilation before breath-holding. The content is often recorded and shared on social platforms.
Risks and Reported Outcomes
Medical experts warn that even brief oxygen deprivation can cause seizures, brain injury, or death. Studies and news reports document cases of serious harm linked to these challenges, especially among adolescents. The behavior is not a safe game and carries documented physical risks.
Platform Responses and Safe Alternatives
Major platforms have updated policies to limit promotion of content that encourages self-harm or dangerous challenges. Search results may surface warnings, age restrictions, or removal of videos that violate community guidelines. For accurate information on risks and prevention, refer to established health organizations such as World Health Organization self-harm fact sheet.
