You've probably seen the videos. Someone on TikTok or a grainy YouTube upload from 2012 holds their breath, squats down, and then stands up fast while a friend presses on their chest. They slump. Their eyes roll back. For a second, it looks like a cheap magic trick or a weirdly effective "hack" for instant sleep. But here’s the thing: trying to figure out how to pass out on command isn't a party trick. It's a deliberate attempt to induce syncope, which is the medical term for a temporary loss of consciousness due to a drop in blood flow to the brain.
It's dangerous. Seriously.
When you force your body to shut down, you aren't "resetting" anything. You are depriving your brain of oxygen. Doctors call this cerebral hypoxia. Even a few seconds of this can lead to permanent neurological issues, or worse, your heart could simply decide not to start back up correctly. It's a gamble with your central nervous system that just isn't worth the five-second "high" or the social media clout.
The Mechanics of Fainting: What’s Actually Happening?
To understand why "commanding" your body to faint is so risky, you have to understand how your body stays awake in the first place. Your brain is a resource hog. It requires a constant, high-pressure stream of oxygenated blood. This is managed by the autonomic nervous system—specifically the balance between the sympathetic (fight or flight) and parasympathetic (rest and digest) systems.
Fainting usually happens because of a sudden drop in blood pressure or heart rate. This is often triggered by the vagus nerve. In a natural vasovagal syncope event—like when someone faints at the sight of blood—the body overreacts to a stimulus, causing blood vessels to dilate and the heart rate to slow down. Gravity then pulls the blood toward your legs. Your brain, sensing the shortage, basically pulls the emergency brake and "reboots" by making you fall down. Why? Because when you’re horizontal, it’s easier for blood to reach your head.
But when people try to force this, they often use the Valsalva maneuver or carotid sinus massage. These aren't just "moves." They are clinical interventions that can go horribly wrong. By holding your breath and straining, you increase intrathoracic pressure. This prevents blood from returning to the heart. When you finally release and stand, your blood pressure craters.
The Physiological Toll of Forced Unconsciousness
Dr. Robert Glatter, an emergency physician at Lenox Hill Hospital, has spoken extensively about the "choking game" and similar trends. He notes that the immediate risk isn't just the faint itself—it’s the seizure-like activity that often follows. You might see someone's limbs twitching. That isn't "dreaming." That's the brain struggling to cope with an acute lack of oxygen.
There are also physical injuries. When you lose consciousness, you lose "postural tone." You become a ragdoll. If you aren't caught by someone, your head is the first thing to hit the floor. Traumatic Brain Injuries (TBIs), skull fractures, and broken teeth are common side effects of these "challenges."

Short-term vs. Long-term Damage
- Brain Cell Death: It only takes a few minutes of oxygen deprivation to kill neurons. While a five-second faint might not cause massive necrosis, repeated attempts certainly lead to cumulative damage.
- Cardiac Arrhythmia: Forcing your heart rate to drop suddenly can trigger an irregular heartbeat. In rare cases, this leads to cardiac arrest.
- Seizures: Many people who try to pass out on command experience "myoclonic jerks." These look like small seizures and indicate the brain is in distress.
- Vision Loss: Sudden changes in ocular pressure can cause hemorrhages in the eyes.
Honestly, the human body is remarkably resilient, but it’s not designed to be turned off and on like a light switch.
Why Do People Even Want to Do This?
It's usually curiosity. Or peer pressure. Sometimes it’s a misguided attempt to deal with insomnia or anxiety. There’s a misconception that "passing out" is the same as "falling asleep."
It’s not.
Sleep is a complex, organized neurological state involving specific brain wave patterns like REM and deep sleep (delta waves). Fainting is a collapse of the system. You don't wake up feeling refreshed after a forced faint; you wake up disoriented, usually with a massive headache and a feeling of "brain fog" that can last for hours.
If you’re looking for a way to quiet your mind or fall asleep faster, there are physiological triggers you can use that don't involve starving your brain of oxygen. Methods like the "Military Sleep Technique" or progressive muscle relaxation actually work with your nervous system rather than attacking it.

The Legal and Social Reality
In many jurisdictions, encouraging others to engage in activities where they pass out on command can lead to legal trouble. If you’re filming a friend doing this and they hit their head or suffer a stroke, you could be held liable. Schools and community centers have ramped up education on this because the "choking game" (also known as "Space Monkey" or "The Fainting Game") has resulted in hundreds of documented deaths worldwide over the last two decades.
The CDC (Centers for Disease Control and Prevention) has highlighted that most of these fatalities occur when someone tries to do it alone. Without someone to catch them or intervene, a temporary faint can turn into a permanent tragedy.
Healthier Alternatives for Relaxation and "System Resets"
If the goal is to feel a "buzz" or to relax quickly, there are much safer ways to manipulate your physiology.
Breathing exercises like Box Breathing (used by Navy SEALs) or the 4-7-8 method can stimulate the vagus nerve in a controlled, safe way. This lowers your heart rate and reduces cortisol without making you lose consciousness. You get the calm without the brain damage.
Another option is cold water immersion. Splashing ice-cold water on your face triggers the "Mammalian Dive Reflex." This naturally slows the heart rate and redirects blood flow to the brain and heart. It’s a literal "reset" button for the nervous system that is used by therapists to help patients during panic attacks.
Moving Toward Better Habits
Understanding your body’s limits is a sign of intelligence, not a lack of bravery. If you have been searching for ways to how to pass out on command, it’s worth asking yourself what you’re actually trying to achieve.
- If it's for a "high": Understand that this is just cellular suffocation.
- If it's for sleep: Look into sleep hygiene or see a doctor about potential sleep apnea or insomnia.
- If it's for a video: It’s not worth the risk of a TBI or a permanent seizure disorder.
The best thing you can do is educate your friends. When you see someone talking about "fainting hacks," call it what it is: a medical emergency.
Actionable Next Steps for Safety
- Check your vitals: If you have fainted recently (voluntarily or involuntarily), see a doctor to ensure you haven't caused an undiagnosed arrhythmia or concussion.
- Learn the 4-7-8 technique: Inhale for 4, hold for 7, exhale for 8. It’s the safest way to "force" your body into a state of deep relaxation.
- Hydrate and Monitor: Many "natural" faints are caused by dehydration or low blood sugar. Make sure you’re eating regular meals and drinking enough water to maintain blood volume.
- Spread Awareness: Talk to younger siblings or friends about the dangers of "blackout" challenges. The more people know the science behind the "reboot," the less likely they are to try it.
Syncope is a symptom that something is wrong. Don't make it a hobby. Your brain is the only one you've got; keep the oxygen flowing.
