A cough is one of the most common reasons people seek medical care — and one of the most frequently mistreated. The right approach depends entirely on what’s causing it. A dry cough from forced-air heating responds to a humidifier. A productive cough from bronchitis may need clinical treatment. Knowing the difference matters, and using the wrong remedy can make things worse or delay care you actually need.
Why You’re Coughing: The Most Common Causes
Before reaching for a remedy, it helps to understand the type of cough you’re dealing with.
Dry cough — produces no mucus, often feels like a tickle or scratchiness in the throat. Common causes include dry indoor air, post-nasal drip from allergies or a cold, acid reflux (GERD), or the tail end of a viral infection after active illness has resolved.
Wet or productive cough — brings up mucus or phlegm. Often associated with respiratory infections, including bronchitis, pneumonia, sinusitis, or the flu. The color and consistency of mucus can offer clinical clues: clear or white typically signals viral illness, while yellow or green may indicate bacterial infection.
Persistent or chronic cough — lasting more than 3 weeks. Warrants clinical evaluation to rule out asthma, GERD, post-nasal drip, or less common causes.
Home Remedies That Actually Help
Honey
One of the most evidence-backed remedies for cough — particularly a dry or irritated cough. A teaspoon of raw honey coats and soothes the throat. Studies comparing honey to over-the-counter cough suppressants have found it equally effective or better for reducing cough frequency and severity. (Note: honey should never be given to children under 12 months due to botulism risk.)
Steam and Humidity
Dry air is a major contributor to nighttime coughing, especially in NYC apartments during winter. A cool-mist humidifier in the bedroom can significantly reduce cough frequency. In the short term, a hot shower or leaning over a bowl of steaming water (with a towel over your head) adds moisture to irritated airways.
Saltwater Gargling
Dissolving half a teaspoon of salt in eight ounces of warm water and gargling for 30 seconds reduces throat inflammation and can temporarily calm a dry or scratchy cough. Effective, free, and clinically sound.
Elevation While Sleeping
Coughs are often worse when lying flat because post-nasal drip flows down the throat and acid reflux is more likely. Propping your head up with an extra pillow (or raising the head of your bed slightly) can reduce nighttime coughing substantially.
Staying Hydrated
Fluids help thin mucus, making it easier to clear. Warm liquids — broth, herbal tea, warm water with honey and lemon — are particularly soothing for an irritated throat and can reduce cough reflex sensitivity.
Over-the-Counter Options
Dextromethorphan (DXM) — found in products like Robitussin DM and NyQuil — is the most common OTC cough suppressant. It works best for dry, non-productive coughs. It will not help (and may hinder) a wet cough, where the goal is to clear mucus.
Guaifenesin (Mucinex) is an expectorant that thins mucus, making productive coughs more effective. It’s most useful when you have chest congestion and need help clearing it.
Menthol lozenges (Halls, Ricola) create a cooling sensation that can temporarily reduce cough frequency by stimulating cold receptors in the throat. Not a treatment, but useful for symptom relief.
When Home Remedies Aren’t Enough
Most coughs from viral upper respiratory infections resolve on their own within 1–3 weeks. But some coughs indicate a condition that needs clinical evaluation and treatment — and home remedies won’t resolve them.
Call a clinician if your cough is accompanied by fever above 101°F, if you’re producing thick green or yellow mucus that’s getting worse (not better) after several days, if you have shortness of breath or chest tightness, if you’re wheezing, if the cough has lasted more than three weeks without improvement, or if you cough up blood. These can indicate bronchitis requiring antibiotics, pneumonia, asthma, or other conditions that need in-person assessment and treatment.
How Sickday Evaluates and Treats Persistent Coughs
When a cough crosses from “uncomfortable” to “concerning,” Sickday’s licensed clinicians come to your location anywhere in New York City — typically within 90 minutes. During the visit, your clinician listens to your lungs, assesses your breathing, reviews your symptoms and their duration, and determines whether your cough is viral (self-limiting) or bacterial (requiring antibiotic treatment). If a prescription is needed, it’s sent to your pharmacy during the visit.
Frequently Asked Questions
How do I know if my cough is bronchitis?
Bronchitis typically presents as a wet, productive cough lasting more than a week, often following a cold. You may have fatigue, mild fever, and chest discomfort. Only a clinical evaluation can confirm the diagnosis — a licensed clinician will listen to your lungs and assess your symptoms.
Should I take a cough suppressant or an expectorant?
It depends on the type of cough. Dry, non-productive cough → suppressant (dextromethorphan). Wet, mucus-producing cough → expectorant (guaifenesin). Taking a suppressant for a wet cough can trap mucus in the lungs, which is counterproductive.
Why does my cough get worse at night?
Lying flat causes post-nasal drip to pool at the back of the throat and makes GERD more likely — both trigger coughing. Elevating your head and running a humidifier are the most effective countermeasures for nighttime cough.
Can I get antibiotics for a cough via house call?
If your clinician determines your cough has a bacterial cause — such as bacterial bronchitis — they can prescribe antibiotics during the house call visit. Viral coughs do not benefit from antibiotics, and a good clinician will tell you that clearly rather than prescribe unnecessarily.
Cough that won’t quit? Sickday licensed clinicians come to your home or office anywhere in NYC — typically within 90 minutes — to listen, evaluate, and treat. Book a house call.
