Q. Is it normal for a cough to worsen at night?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Yes, it is relatively common for a cough to worsen at night, and this phenomenon is often referred to as "nighttime coughing." There are several reasons why a cough may become more bothersome when lying down and trying to sleep:
1. Postnasal Drip: When you lie down, mucus can accumulate in the back of your throat, especially if you have postnasal drip due to allergies or a respiratory infection. This can trigger coughing as your body tries to clear the mucus.
2. Reflux: Gastroesophageal reflux disease (GERD) is a condition in which stomach acid flows back into the esophagus, often worsening when lying down. The acid can irritate the throat and trigger coughing.
3. Asthma: Some individuals with asthma experience nighttime coughing, known as "nocturnal asthma." This may be due to increased airway inflammation and sensitivity during sleep.
4. Dry Air: The air in your bedroom may be drier at night, especially in the winter when heating systems are used. Dry air can irritate the throat and airways, leading to coughing.
5. Environmental Allergens: Allergens such as dust mites, pet dander, or mold spores in your bedroom can lead to nighttime coughing if you are allergic to them.
6. Medication Timing: The timing of certain medications, such as antihypertensive drugs known as ACE inhibitors, can lead to nighttime coughing as a side effect.
7. Cough-Reflex Sensitivity: Some individuals have heightened cough reflex sensitivity at night, which can make them more prone to coughing when lying down.
To alleviate nighttime coughing, you can try the following:
1. Elevate Your Head: Use an extra pillow or a wedge pillow to elevate your head and upper body while sleeping. This can help reduce the accumulation of mucus in the throat.
2. Stay Hydrated: Drink plenty of fluids throughout the day to keep your throat moist and reduce irritation.
3. Humidifier: Use a humidifier in your bedroom to add moisture to the air, especially during dry seasons.
4. Avoid Trigger Foods: If you have GERD, avoid eating large meals, acidic or spicy foods, and caffeine close to bedtime.
5. Allergen Control: If allergies are the cause, take steps to reduce allergen exposure in your bedroom, such as using allergen-proof mattress and pillow covers.
6. Medication: If your cough is due to an underlying condition like asthma or GERD, follow your healthcare provider's recommendations for managing these conditions.
If your nighttime cough persists or worsens, or if it is accompanied by other concerning symptoms, consult a healthcare professional for a proper evaluation and treatment plan
