Drink More Water
Sip more H2O or juice. It’ll help thin out mucus and encourage drainage. Hot tea is another good option. Don’t overdo caffeine or alcohol. Both can make you dehydrated. Alcohol can worsen sinus swelling. Aim for eight or more 8-ounce glasses of water or other healthy drinks each day.
Try Nasal Irrigation
It’s also called nasal wash, and it can help keep your sinuses clean and clear. You use a mild, sterile saline solution to flush out the mucus and allergens causing your congestion. Lean over the sink, squirt the solution into one nostril, and let it drain through your nasal cavity and out the other nostril. Keep your mouth open and don’t breathe through your nose.
