One of the common winter complaints that accompanies a cold or flu infection is a cough. You can protect yourself from colds by boosting your immune system.

A cough is often the main symptom of a viral infection in your throat, main airway or the airways going into your lungs.

Even though it can be annoying a cough is sign that your body is doing it job to try to clear your airways if they are blocked by something, such as phlegm (mucus), smoke, dust or a piece of food.

Most coughs clear up on their own and you can take care of yourself without visiting your doctor. However, if your cough lasts for more than three weeks, then see your doctor.

If you have a cough and you’re short of breath, cough up blood or have unexplained problems like weight loss or a high temperature (fever), you should see your GP urgently.
