What to do to soften dry cough?
Some "home treatments" may help alleviate the discomfort caused by dry cough in less severe cases:
- Drinking water constantly: Liquids in general, preferably water, are the best home remedies for coughing, as they facilitate the movement of the mucus;
- Drink chamomile teas, lemongrass and sweet fennel;
- Sleep with the head higher, using more pillows;
- Leave the surroundings of the house well ventilated.
Coughing is a natural reflection of the body, being a important mechanism of defense of the respiratory system, responsible for the removal of excess secretion, foreign bodies and infectious micro-organisms of the airways.
