9.Gargle Saltwater
A saltwater gargle is usually a sore throat remedy, but it’s worth trying for coughs, too. The extra moisture can thin mucus and help wash out things that irritate your throat, much like a saline rinse does for the nose. Mix 1/4 to 1/2 of salt into 8 ounces of warm water, tip your head back, gargle, and then spit the mixture out.
10.Humidifier
Though keeping the air moist can help ward off a dry cough, take extra care with humidifiers. Dust mites are the No. 1 allergen and grow best when conditions are too moist. Mold can also grow inside humidifiers if you don’t keep them clean. Both can make coughs worse instead of better.
