In Briançon, in the Hautes-Alpes, a tragedy shakes up an entire town. On October 24, Macéo, 14, died while trying to reproduce a TikTok challenge called “mattress surfing”. The principle? Being towed on a mattress attached to a moving car.
An absurd idea turned tragedy
That evening, among friends, the experience turns into a nightmare. The car driven by an 18-year-old changes direction; Macéo, lying on a box spring, is thrown into the Cerveyrette river, a tributary of the Durance. His body was not found until the next day.
“The victim had climbed on it in order to be dragged (…). He was ejected into the river when the vehicle turned around,” said the public prosecutor of Gap, Marion Lozac’hmeur.
The driver, who admitted his responsibility, was placed under judicial supervision and will be tried for manslaughter.
The black mirror of TikTok “challenges”
THE mattress surfing is not an isolated case: a 17-year-old teenager has already died from it in the United States. These absurd challenges,
One Chip Challenge (eat an ultra-hot pepper)
Paracetamol Challenge (ingest a toxic dose of medication), to name but a few, abound on the networks. Every week, a new “fashion” involves the lives of young people fascinated by risk, fleeting glory and likes.
But why this fascination with danger? Are our teenagers devoid of fear, or poorly equipped to discern risk?… or idiots?
Amélie Boukhobza, psychologist specializing in adolescence, sheds light on this paradox.
“From our adult perspective, we say to ourselves: how can we not see the danger? But let’s remember that adolescence is exactly that: risk-taking”
A brain still under construction
A teenager doesn’t think like us. At 14, the brain is still under construction. The frontal lobe, the seat of reasoning, anticipation and impulse control, is not yet fully functional.
“The engine is ready, but the brakes are not yet”summarizes the psychologist.
During this time, the limbic system, which manages emotions and sensation-seeking, is running at full speed. Result: an imbalance between drive and prudence. In short, adolescents know that danger exists… but their brain does not interpret it as an alarm.
“It’s not that they aren’t afraid. It’s that fear doesn’t stop them yet,” she explains.
Face death to feel alive
But that’s not all. Taking risks at this age also means confronting the limit, testing your body, death, the rules, the eyes of others…
“It’s a way of constructing one’s identity, of feeling oneself exist other than in conformity”adds Amélie Boukhobza.
And in this context, social networks amplify everything: the staging, the search for recognition, the glorification of danger. Each challenge becomes a test of courage, a rite of passage in plain sight…. without realizing the definitive side.
Setting benchmarks, the duty of parents
But what can be done to prevent these risks of which parents are well aware. Faced with these excesses, the psychologist pleads for truer adult speech.
“Even if we sometimes have the impression that nothing is happening, prevention makes perfect sense. What we say sets benchmarks, creates a foundation of consciousness, an internal framework.”
It is not a question of lecturing, but of dialogue, of putting fear, risk and death into words. Because sometimes, between challenge and disaster, the line is too fine.
How to do it? Dr. Kierzek, emergency physician and medical director of True Medical, recalled this recently:
- Establish an open dialogue with young people
Discuss their online activities regularly.
Encourage them to express any doubts or concerns about the challenges they observe. - Make them aware of digital dangers
Explain the physical and psychological consequences of dangerous challenges.
Use educational resources, such as those from e-Enfance or Cybermalveillance.gouv.fr - Monitor and support them
Monitor your children’s digital activity, especially on TikTok and Instagram.
Pay attention to the warning signs: change in behavior, unexplained injuries, isolation.
