1. Hypoxia (No Oxygen = Brain Starvation)

• Your body needs about 21% oxygen to function.

• Helium has zero oxygen. So breathing it is like sitting in a room full of invisible poison gas.

• First signs: headache, dizziness, confusion → then unconsciousness → death in minutes.

2. "Asphyxiation Room" Trap

• If you're in a small room and release a lot of helium (like from balloons or tanks), it can displace all the air.

• Even if you don’t breathe it directly, you’ll still suffocate just by standing there.

• This happened in real cases—people passed out in party supply stores. Real talk.

3. Lung Collapse – Barotrauma

• Inhaling helium from a pressurized tank = instant danger.

• The pressure can rupture your lungs, causing air to leak into your chest cavity → collapsed lung (pneumothorax).

• Pain, shortness of breath, and if untreated? Yeah, game over.

4. Delayed Symptoms

• Some people breathe helium, feel fine, then collapse a few minutes later.

• Why? Your brain keeps burning oxygen, and once it runs out? Boom—blackout.

• Sometimes, people don’t even get the chance to call for help.

5. Helium Is Colorless, Odorless, Tasteless

• You can’t detect it in the air.

• Makes it super sneaky—you don’t even know you’re breathing it instead of oxygen until it's too late.

6. Deaths Have Happened

• Sadly, this ain’t just a warning.

• There have been real cases where teens or kids died trying to make funny voices or doing dares on camera.
