Causes
The underlying cause has not been scientifically proven, but many believe it may be a vascular disorder because of the association with flushing, redness, and visible blood cells. Some physicians have also speculated that flushing may involve the nervous system, since it is triggered with people who are under emotional stress. Some other triggers are alcohol, spicy foods, sunlight, and hot foods.
