you might’ve seen videos of athletes sniffing something right before lifting heavy weights.
So, it’s actually called smelling salts—and as soon as someone sniffs them, it’s like getting hit by a jolt of electricity.
That’s because they contain a chemical called ammonium carbonate, which releases ammonia gas.
When you inhale it, the gas creates a burning sensation in your nose and lungs.
This triggers a reflex that makes you breathe faster, pulling in more oxygen to your brain.
And it gives you a quick boost before a heavy lift.
