Blackout / Choking Challenge

The blackout challenge involves choking oneself until passing out, then waking up — for a brief euphoric rush. It has killed at least a dozen children under 14 since 2021, several in their own bedrooms with no one home. TikTok now blocks the search term, but related and rebranded videos continue to surface. The injury is often fatal on the first attempt.

TikTok originally; algorithmic recommendation continued to push the videos to minors even after the search ban. Rebranded versions appear on Instagram Reels and YouTube Shorts.

A version of the 'fainting game' has existed in U.S. childhood for over fifty years. The TikTok-amplified version has been documented in coroner reports since 2020.

• Most children try it alone, in a closet, behind a closed bedroom door. Death by hypoxia happens in minutes; CPR is rarely in time.
• TikTok's algorithm has been named in multiple wrongful-death lawsuits for recommending the videos to kids who never searched for them.
• The age range that dies from it is 8–14, younger than most safety conversations target.

• Death by hypoxia or by asphyxiation when the teen loses consciousness while bound.
• Brain injury from non-fatal episodes — even 'successful' blackouts repeated over time cause cognitive damage.
• Co-occurrence with other deprivation challenges (breath-holding, hyperventilation games) compounds the risk.

• Have the conversation early — by age 8 if your child has any TikTok or YouTube exposure. Name the challenge. Describe what happens.
• Watch for ligature marks on the neck, broken capillaries in the eyes, unexplained ropes/belts/cords in the bedroom, headaches, or sudden cognitive changes.
• If you find your child unresponsive: call 911 immediately, begin CPR, and remove any constriction from the neck before chest compressions.
