Many people believe that colds and flu are caused by bacteria, but this is simply incorrect. Colds and flu are caused by viruses, and using antibiotics to treat a viral infection is inappropriate and completely ineffective.
Viruses are orders of magnitude smaller than bacteria and have entirely different structures that make antibiotics useless. (Occasionally antibiotics are required if there is a secondary bacterial sinus infection or bronchitis/pneumonia, but this is the rare exception.)
It is also important to recognize that, although a virus triggers your cold or flu symptoms, it is not the real cause of the illness.
So, what is the real cause of colds and flu?
My simple and short answer has always been that it’s due to an impaired immune system. That’s still true. However, research has confirmed that “catching” colds and flu may be a symptom of an underlying vitamin D deficiency! Less than optimal vitamin D levels will significantly impair your immune response and make you far more susceptible to contracting colds, influenza, and other respiratory infections.
Although there are many ways you might end up with a weakened immune system, the more common contributing factors are:

- Inadequately managing emotional stressors in your life
