It is very common to feel congested when lying down. When you lie flat, gravity no longer helps drain fluids, and increased blood flow to your head causes the blood vessels in your nasal passages to swell, blocking your airway. Sitting up naturally reverses this. While Vicks can offer temporary comfort, using medicated decongestant sprays daily can actually make congestion worse over time. I suggest trying to elevate your head with an extra pillow and using a gentle saline nasal spray instead. Please consult a doctor for a personalized plan.

Why does my nose get blocked only when I lie down to sleep at night, requiring me to use Vicks daily, but clears up when I sit up?
