At night when you sleep, mucus trickles down and collects in your throat and lungs. When you wake up, the mucus begins to break up, causing you to start coughing. A dry cough is unproductive, meaning that it does not produce phlegm.
8 causes of dry cough at night and in the morning
1. Cold or flu
Dry morning coughs are often the lingering effects of the common cold or flu. Viral infections typically last about a week, but symptoms like coughing may persist longer. The recovery process takes a bit longer if the virus infects the upper airway.
2. Postnasal drip
When excess mucus from the nasal passage trickles down into the throat, it can trigger a cough. Substances can irritate the nasal membranes and produce thin, runny mucus. These include:
Other symptoms of post-nasal drip include:
Asthma occurs due to the swelling and narrowing of the airways. With cough-variant asthma, a severe cough is the most common symptom and it may be wet or dry. The coughing is often worse at night or in the morning.
Allergens such as pollen, dust mites, or pet dander can trigger an array of symptoms, including a dry cough. For example, dust mites in your bedding could be causing you to cough at night. Pollen counts are generally highest in the morning, and can therefore cause a morning cough in people with pollen allergies. Other symptoms of allergies include:
5. Gastroesophageal reflux disease (GERD)
- Regurgitation of food or sour liquid
- Chest pain
- Feeling like there’s a lump in the back of your throat
- Mild hoarseness
- Chronic cough
- Chronic sore throat
- Difficulty swallowing
6. Dry mouth
Dryness in the throat can cause irritation and lead to a cough. Dry mouth and throat may be caused by:
- Not drinking sufficient fluids
- Sleeping in a dry room
- Sleeping with your mouth open.
Other symptoms of dry mouth may include:
- Trouble swallowing
- Hoarse voice
7. Chronic obstructive pulmonary disease (COPD)
COPD is a group of diseases that causes chronic lung inflammation, leading to airflow obstruction and breathing disorders. It includes emphysema, chronic bronchitis, and asthma. Coughing caused by COPD is usually worse in the morning, although it is typically wet, not dry. Other symptoms of COPD include:
8. ACE inhibitors
ACE inhibitors are typically prescribed to control high blood pressure and can cause a dry cough that worsens at night or in the morning. If you have a mild cough, your doctor may prescribe another ACE inhibitor. However, if your cough is severe, your doctor may prescribe another class of antihypertensives like angiotensin receptor blockers.
How can you treat a dry cough?
Home remedies to manage dry cough include:
- Sucking on cough drops or lozenges to soothe your throat and prevent irritation
- Running a humidifier while sleeping to keep your throat moist
- Inhaling steam to lubricate your throat
- Irrigating the nasal passages to clear out irritants
- Sleeping with your head elevated to prevent symptoms of gastroesophageal reflux disease (GERD)
- Gargling with warm water to reduce throat inflammation
- Swallowing honey to soothe a sore throat
- Drinking plenty of water to keep your throat moist
If home remedies are not effective, your doctor may recommend the following medications:
- Decongestants: Decongestants are over-the-counter medications that relieve congestion by limiting blood flow to the swollen tissue. This eventually causes it to shrink, thereby making breathing easier.
- Cough suppressants and expectorants: Cough suppressants or antitussives work by blocking the cough reflex, whereas expectorants work by thinning the mucus to help you expel it more effectively. Antitussives are ideal for dry nighttime coughs because they prevent your cough reflex from working while you sleep.
