Your body's protective means of riding substances from breathing passageways, coughing can happen voluntarily and involuntarily. Since it is a built-in protective measure, coughing should never be completely suppressed, but there are times when you need to soothe a cough, especially so you can sleep.
Coughing can range from a being mild nuisance to a debilitating event. There are a few things that you can do to soothe a cough at home:
Cough suppressants, also known as antitussives, are used for treating dry coughs. Some common over-the-counter and prescription cough suppressants contain varying degrees of codeine or dextromethorphan. Both reduce the impulse to cough by muting the nerve at the brain stem that controls the chest area. Interestingly, recent studies indicate that eating 50 grams or more of dark chocolate can help suppress persistent coughs, since dark chocolate contains theobromine—a natural antitussive, superior to codeine.
Productive coughs that contain phlegm are treated with expectorants. The two most widely used expectorant drugs are guaifenesin and acetylcysteine. Expectorants dilute thick mucus as well as lubricate the irritated respiratory tract. While you can purchase guaifenesin as an over-the-counter cough medicine, acetylcysteine can only be obtained by prescription, since it is administered with special inhalation equipment.
Whatever type of cough you have, if it lasts more than a week, make an appointment to see your doctor. Treating cough symptoms will only soothe your cough. Finding the cause of your cough will stop you from coughing.
