1.Steam Therapy – this is the most common way to treat mucus accumulation. Many even claim that this is the best way to remove excess mucus from the lungs. The steam works by loosening the mucus and liquefying it so that it can be expelled from the body.
You can do steam therapy by going in a steam shower for a full 10-20 minutes. You can also put hot water in a bowl and hold your face about 6 inches over the bowl. Cover your head with a small towel to contain the vapors so you can inhale the steam.
