Cough

🌿 Overview

A cough is the body's way of clearing the throat and lungs. Most coughs follow a cold and fade within a couple of weeks. Honey, warm fluids, steam, and humid air calm the urge to cough while the airways recover.

A cough is a reflex — the body's way of clearing the airways of mucus or irritation. It's a symptom, not a disease, and most coughs come after a cold and fade within a couple of weeks as the airways recover. A productive cough brings up mucus and is doing useful work; a dry cough is just irritation, and it's the one most worth soothing. The aim is to calm the irritation and loosen mucus while the body heals, not to silence a cough that's clearing the chest. Warmth, moisture, and soothing coatings do most of the work. A cough that lingers beyond three weeks, brings up blood, or comes with breathlessness or a high fever needs a doctor.

Common signs

• Dry or productive cough
• Tickle or irritation in the throat
• Worse at night
• Sometimes chest discomfort from coughing

• The tail end of a cold or other viral infection
• Post-nasal drip from a cold or allergies
• Dry or cold air irritating the airways

🍽️ Eating to help

Food is one of the gentlest medicines — small, steady changes help most.

Favor these

• Warm broths, soups, and herbal teas
• Honey and warm lemon water
• Ginger, garlic, and onion
• Plenty of water to thin mucus

Go easy on

• Cold, dry, or very sugary foods if they worsen the tickle
• For some, dairy can feel like it thickens mucus
• Smoking and smoky environments

See a doctor if a cough lasts more than three weeks, brings up blood, or comes with shortness of breath or chest pain.
