The excess build-up of mucus and phlegm in the airways can hamper breathing. Its thick consistency makes it difficult to clear, but by maintaining adequate water intake, the problem can be controlled. Experts recommend drinking at least eight glasses of water each day to prevent mucus from forming or thin what has collected. Some even say drinking warm or slightly hot water can work even better than cold to loosen mucus and phlegm. While plain water is best, other drinks and liquids like herbal tea and clear broths can work as well.
Indoor air should also be kept on the moist side, which can be accomplished with a humidifier. Dry air while sleeping can make breathing more difficult and worsen the build-up of mucus and phlegm.
