Nighttime coughs can be particularly bothersome, disrupting sleep for both the individual and their family. Here are 12 tips to help alleviate nighttime coughs and improve sleep quality.
1. Use Honey
Honey has been shown to be effective in reducing nocturnal cough and improving sleep quality. Studies have demonstrated that honey can be more effective than over-the-counter medications like dextromethorphan and diphenhydramine1 3 4 7. A single dose of honey before bedtime can significantly reduce cough frequency and severity.
2. Try Vapor Rub
Applying vapor rub to the chest and neck before bedtime can help alleviate cough and congestion. Research indicates that vapor rub is superior to no treatment and petrolatum in providing symptomatic relief for nocturnal cough and sleep difficulty6.
3. Use a Humidifier
A humidifier can add moisture to the air, which can soothe irritated airways and reduce coughing. Keeping the air moist can help prevent the throat from becoming dry and irritated, which can trigger coughing.
4. Elevate the Head
Elevating the head with an extra pillow can help reduce postnasal drip and coughing. This position helps keep mucus from pooling in the back of the throat, which can cause irritation and coughing.
5. Stay Hydrated
Drinking plenty of fluids can help thin mucus and keep the throat moist. Warm liquids like herbal tea or warm water with honey can be particularly soothing.
6. Use Nasal Sprays
For those with coughs associated with allergic rhinitis, using a nasal spray like mometasone furoate can help reduce nasal inflammation and associated cough2. This treatment has been shown to improve both daytime and nighttime cough severity.
7. Avoid Irritants
Avoid exposure to irritants such as smoke, strong odors, and allergens, which can exacerbate coughing. Keeping the sleeping environment clean and free of dust can also help reduce nighttime cough.
8. Practice Good Sleep Hygiene
Maintaining a regular sleep schedule and creating a comfortable sleep environment can help improve overall sleep quality. This includes keeping the bedroom cool, dark, and quiet.
9. Use Over-the-Counter Medications
While some studies suggest that over-the-counter medications like dextromethorphan and diphenhydramine are not superior to placebo5, they may still provide some relief for certain individuals. Always consult with a healthcare provider before using these medications.
10. Try Herbal Remedies
Herbal remedies such as ginger tea or licorice root can help soothe the throat and reduce coughing. These natural remedies can be a good alternative for those who prefer not to use conventional medications.
11. Keep the Air Clean
Using an air purifier can help remove allergens and irritants from the air, which can reduce coughing. This is particularly important for individuals with allergies or asthma.
12. Consult a Healthcare Provider
If nighttime cough persists despite trying these remedies, it is important to consult a healthcare provider. Persistent cough can be a sign of an underlying condition that may require medical treatment.
By incorporating these tips, individuals can find relief from nighttime coughs and enjoy a more restful night’s sleep.
