The cold you get after blowing the air conditioner is a cold. It's usually due to fatigue, lack of rest, plus exposure to wind or cold. Wind-heat and colds are mostly caused by constipation, which is often a Yangming Meridian syndrome.

The difference between the two is: Wind-cold cold is a symptom of wind-cold attack and lung-qi disease. The symptoms include feeling cold, mild fever, no sweating, headache and body aches, nasal congestion and runny nose, cough and spitting out thin white phlegm, not being thirsty or preferring hot drinks when thirsty. Wind-heat and cold cause fever in the body and imbalance of lung qi. Symptoms include severe fever, head bloating and headache, sweating, sore throat, cough, sticky or yellow phlegm, stuffy nose and yellow discharge, and thirst and preference for drinking.
