Emotional & Energetic Causes Cold & Flu

What are the main common emotional and energetic reasons for getting a cold? 

When we are ready to release old belief systems and make a quantum leap to a new perspective, where we release old beliefs and bring in new or more truthful beliefs, it can take a toll on our body, and our body goes into a cold-slash-flu state to detox all of these old mental frameworks out of our mental body. 

The flu and the cold has always been seen as a way for the body to detoxify and cleanse in the holistic community. The same perspective can be put onto emotional release, since, as we know, as I've spoken about it before, all the bodies are intertwined. 

Therefore, detoxifying the physical opens up pathways to detoxify the emotional, mental, ethereal, spiritual.
