Why Bronchitis Cough Worse at Night
Bronchitis is a common respiratory condition that affects millions of people worldwide. One of the most frustrating symptoms of bronchitis is the persistent cough. However, many patients notice that their cough becomes worse at night, leaving them restless and uncomfortable. This article aims to explore the reasons behind why bronchitis cough is often more severe at night.
Increased Airway Sensitivity at Night
One of the primary reasons why bronchitis cough worsens at night is the increased airway sensitivity. During the day, the body’s natural defense mechanisms, such as the immune system, are more active. However, as the body relaxes during sleep, the airways become more sensitive to irritants and allergens. This heightened sensitivity can lead to a more pronounced cough as the body tries to clear the airways of mucus and irritants.
Decreased Saliva Production at Night
Another factor contributing to the worsening of bronchitis cough at night is the decrease in saliva production. Saliva plays a crucial role in keeping the throat moist and protecting it from irritants. During sleep, saliva production decreases, leading to a dry throat. This dryness can exacerbate the cough, as the airways are more prone to irritation and inflammation.
Changes in Body Temperature
The body’s temperature typically drops during sleep, which can also contribute to the worsening of bronchitis cough. Lower body temperatures can cause blood vessels in the respiratory tract to constrict, leading to increased airway resistance. This resistance makes it more difficult for the airways to clear mucus, resulting in a more severe cough.
Postural Changes During Sleep
The way we sleep can also impact the severity of bronchitis cough at night. When lying down, the position of the body can cause mucus to accumulate in the bronchial tubes. This mucus can irritate the airways and trigger a more intense cough. Additionally, the position of the head and neck can change the angle of the airways, making it easier for mucus to accumulate and contribute to coughing.
How to Manage Bronchitis Cough at Night
To alleviate the discomfort caused by bronchitis cough at night, there are several strategies you can try:
1. Use a humidifier: Adding moisture to the air can help keep your throat moist and reduce coughing.
2. Prop yourself up: Using pillows to elevate your head and upper body can help prevent mucus from pooling in the bronchial tubes.
3. Stay hydrated: Drinking plenty of fluids throughout the day can help keep your throat moist and reduce coughing.
4. Avoid irritants: Minimize exposure to cigarette smoke, dust, and other allergens that can exacerbate your cough.
5. Over-the-counter remedies: Consider using cough suppressants or expectorants to help manage your symptoms.
In conclusion, bronchitis cough often worsens at night due to increased airway sensitivity, decreased saliva production, changes in body temperature, and postural changes during sleep. By understanding these factors and implementing appropriate strategies, you can help manage your symptoms and get a better night’s sleep.
