In some cases, the sufferer’s cheeks, ears, or neck grow red. Other people’s entire faces burn, or the heat washes over their head like a wave. A person who blushes feels stripped bare, even when fully clothed. A blush can be triggered by shame, guilt, joy, excitement, or irritation, and can strike when we are alone or in the company of others. But it is never under our control. It can happen when we are praised, criticized, or caught off guard. A blush can be a sign of attraction or of “hot” thoughts. Or a person may blush because she realizes she is unprepared for an important discussion or presentation – or at least feels that way. Sometimes it’s enough to drive you crazy, but blushing also has a positive side.
Blushing is just one possible reaction to feelings of shame, which in turn arise under very different circumstances in different people. Some people never blush in embarrassing situations: instead, they may grin, laugh, or involuntarily alter the timbre of their voices. “Social” blushing is also distinct from hot flashes, stage fright, skin diseases, or the reddening of the skin as a result of physical effort, happiness, or alcohol consumption.
