8. You Cough, But Don’t Have a Cold

All that excessive phlegm has to go somewhere, so coughing without a known source could be a sign that your body is too acidic. If you know you have not been exposed to germs and don’t suffer from allergies, than that cough could be a sign your pH is out of balance. If you have a productive cough and don’t have a cold or the flu, you could simply be too acidic for good health.
