To blush is to display redness in one’s face; the term is usually used when the redness is a result of an emotional response, which could reflect embarrassment, shame, or modesty. Blushing can also be associated with being in love. Blushing is generally distinguished, despite a close physiological relation, from flushing, which is more intensive and extends over more of the body, and seldom has a mental source. If redness persists for abnormal amounts of time after blushing, then it may be considered an early sign of rosacea which should be discounted by a GP before entering into hypnotherapy. A medical condition known as Idiopathic craniofacial erythema exists, in which the sufferer blushes strongly with little or no provocation. This is related to social phobia and as with other phobias Hypnosis is useful in investigating and dealing with it’s cause as well as treating the symptom. Erythrophobia (“fear of redness”) refers to pathological blushing.
