What is cough?

A cough is your body’s way of responding when something irritates your throat or airways. An irritant stimulates nerves that send a message to your brain. The brain then tells muscles in your chest and abdomen to push air out of your lungs to force out the irritant.

An occasional cough is normal and healthy. If it persists for several weeks or one that brings up discolored or bloody mucus may indicate a condition that needs medical attention. While an occasional cough is normal, a cough that persists may be a sign of a medical problem including cancer.


How bad is my cough?

Mild: You may have watery eyes, headache and change in your voice.

Moderate: You may experience fever or chills, breathlessness or sore throat. It may limit instrumental activities of daily life (medication management, housekeeping activities, ability to manage finances).

Severe: Urgent medical assistance is needed if you’ve had persistent cough for more than 3 weeks. You may also have chest pain, weight loss, swollen neck or shortness of breath. It may limit self-care activities of daily life (eating, dressing, getting into or out of a bed or chair, taking a bath or shower, and using the toilet). Urgent medical assistance is needed.

How to manage mild cough?

Keep track of your symptom using Ankr (myAnkr web portal or the Ankr app). It will help you describe the discomfort to your doctor or nurse.

  • Over-the-counter remedies can help in a number of ways. Expectorants thin mucus and make it easier to hack up.
  • Drink warm fluids, inhale warm, moist air, and use drops. Add a spoonful of honey to hot tea, or choose a drop that has it.
  • Avoid triggers. If you have allergies or asthma, remove allergens from your home. Keep pets out of your bedroom. Use air conditioners to filter air.
  • Common viruses are the most likely causes. Over time your airways will heal and it will stop.
  • Elevate your head with extra pillows while sleeping.
  • Use cough drops to soothe your throat.
  • Gargle with warm salt water regularly to remove mucus and soothe your throat.
  • Avoid irritants, including smoke, tobacco and dust.
  • Add honey or ginger to hot tea to clear your airway.
  • Use decongestant sprays to unblock your nose and ease breathing.
