Managing a dry cough can be easier with over-the-counter treatments. Cough suppressants and expectorants are two common types that help. Cough suppressants, like dextromethorphan, reduce coughing. Expectorants, such as guaifenesin, thin mucus for easier coughing up13.
Popular options include cough drops, syrups, and tablets. These products mix ingredients to tackle cough symptoms13. Always follow the label to use them safely and effectively.
Staying hydrated and using a humidifier can also help. Drinking water or herbal tea thins mucus and soothes the throat14. Adding moisture to the air with a humidifier can ease cough symptoms13. Combining these methods with over-the-counter treatments can offer relief and improve life quality.
Remember, over-the-counter treatments only provide relief, not a cure. If a cough lasts or comes with other symptoms, see a doctor13.
Making lifestyle changes can help ease dry coughs. Changing how you sleep can reduce throat and airway irritation15. For example, raising your bed by 6–8 inches can help manage coughs, mainly for those with GERD15.
Staying away from common irritants can also lessen coughing15. This means avoiding dust and pollen, which helps those with allergies or sensitivities15. Some research shows honey can be a good cough soother, better than usual care for coughs in upper respiratory infections16.
Drinking plenty of water and using humidifiers can also help with cough symptoms. By avoiding triggers and making these changes, you can lessen coughing and boost your health.

Sleep quality is key in how severe dry coughs are. It helps the body fix and grow new tissues, like in the throat and airways17. When we sleep, our immune system battles infections and swelling. Poor sleep weakens this fight, making recovery harder18.
Good sleep habits, like regular sleep times and a calm bedroom, can boost sleep quality. This can lessen dry cough severity.
To better sleep, avoid screens before bed, keep your room cool and dark, and relax before sleep. Drinking at least 8 glasses of water a day can also help thin out mucus and lessen coughs17. If your cough lasts over 3 weeks or you have other symptoms like fever or trouble breathing, see a doctor right away17.
By focusing on sleep quality and good sleep habits, you can make dry coughs less severe. Research shows a link between poor sleep and asthma control18. This shows how crucial sleep is for respiratory health.
Allergies can cause nighttime dry coughs, often due to seasonal allergies and dust sensitivities19. Inhaling allergens like pollen, pet dander, dust mites, or mold can set off an immune response. This leads to a dry cough19. This cough is dry and doesn't produce mucus, and can become a long-term problem if not treated19.
To fight allergies, it's key to stay away from triggers and use medication when needed. First-line oral antihistamines can help ease symptoms19. Using a humidifier or vaporizer can also help soothe the throat and loosen mucus19. Remember, coughing and trouble breathing can be signs of a serious allergic reaction called anaphylaxis, which needs emergency care19.
About 30% of adults and 40% of children in the U.S. have allergies, with respiratory symptoms being common19. Doctors use skin prick tests or IgE-specific blood tests to find out what allergens are causing the problem19. Knowing the causes and symptoms of allergies helps people manage their symptoms and lessen the impact of nighttime dry coughs20.
