10 Causes of Fainting

Cause #2: Coughing
Don’t worry – if you just have a simple dry cough, chances are you’re not going to pass out from coughing. However, in comparison to the many reasons that people faint, coughing is actually one of the more common causes.
This is because coughing strains your body and reduces the amount of oxygen that is available for the organs - including the brain. People who experience intense fits of coughing, like people who suffer from conditions like bronchitis or pneumonia, may be liable to pass out after having an intense coughing fit.
