Normally, the numerous cilia in the upper respiratory tract remove mucus and "intruders" such as dust particles, sending them to the pharynx. But if something accidentally enters the windpipe (such as a piece of food) or if excess mucus is produced, it triggers a cough reflex. During this powerful reflex, the air is pressed out with great force as the diaphragm contracts, producing a cough that travels up to 80km/hour!
You may be coughing up much mucus, while the person beside you has a dry or tickling cough. It is far from a contest as we explore the various kinds of cough:
Answer these three questions to find out >> which type of cough you have
Is the cough productive, in which case we tend to "rattle" all day long. For that we thank the overwhelming amount of mucus in the respiratory tract that is now so thick that it cannot be easily expectorated So, we keep on coughing until we tire of it...
This productive or "wet" cough is typical during a cold as the body produces mucous to trap invading pathogens. The cold could very well go away after a few days, but don't worry, you do not have to suffer with this cough for days! Solution: A.Vogel Bronchosan®

The children have been tucked in and the dog has finished pawing at their bed to fluff it up. You finally lay your head down next to your partner and quicker than it took for your child to settle, you're struck by a single irritated cough and up goes the house.

Consult a doctor if coughing hurts or if you cough up blood or rust-coloured mucus. If the cough persists more than 3 weeks, this could also indicate something more than a short viral or bacterial infection.
Do not smoke and minimize exposure to second hand smoke from others or tertiary smoke that has seeped into fabrics such as in cars or furniture. Take in some daily extra oxygen by walking outside for instance, but avoid going near contaminated, smoky environments. Make sure to rest sufficiently; this improves resistance.
Coughing is a defense mechanism of the body, aimed at keeping the respiratory tract clean.
The walls of our respiratory tract, from the back of the throat to deep within the lungs, are full of nerve endings. When those are stimulated or irritated, sensory signals reach the cough centre of the brain and trigger a series of coordinated muscle actions which lead to coughing.
The cartilaginous structure (better known as the larynx) is temporarily closed off by the epiglottis, a piece of tissue that acts akin to a lid or cover on the open airway. This is followed almost simultaneously by the contraction of the diaphragm and chest muscles, causing increased pressure in the upper respiratory tract.
As soon as the epiglottis relaxes again, the larynx opens and depending on the individual respiratory capacity, about 1.5 litres of air are forcefully expelled from the lungs via the upper respiratory tract. This leads to the characteristic cough sound.
During this air expulsion, speeds of 150 km/h have been measured, whereby undesired material is pushed out of the upper respiratory tract. At the same time, three thousand miniscule droplets of saliva come free in a cloud that disperses, leaving some to hover in the air with the possibility of being inhaled by those nearby. This sentence alone reminds us why covering our mouths when we cough is so important to reduce contamination or infecting those around us.
