How do nasal decongestants work?

How does it make it seem as though your nose isn’t stuffy anymore? How come I can breathe through one nostril and not the other when I’m congested? How does fixing your positioning (I.e.) putting your head higher help with congestion? 🙂 ur welcome for my 18273729101 questions & ty for ur answers 🙂

Congestion: The tissues in your nose/airways get swollen (usually bc of irritation) and leak a ton of fluid. The blood vessels are usually wide open and send more fluid into the tissue.

Decongestion: Some thing like sudafed (pseudoephedrine) will close up the blood vessels a bit and cause the situation to dry up. But don’t rely on this long term — the effects wane and become more risky as you keep using it.

Holding your head higher and cooling down the area might prevent further swelling in those tissues. Regular neti pot/saline rinses can help draw out the excess fluids while maintaining fluid balance (saline, not plain water). Boosting room humidity can improve skin irritation.
