Erythrophobia: Fear of Blushing and Embarrassment

Erythrophobia (from Greek erythros, red) is a specific phobia characterized by intense fear of blushing in social situations, leading to avoidance and distress.

Clinical Features

• Anticipatory anxiety about blushing.
• Situational avoidance (public speaking, dating, eating in public).
• Paradoxical effect: fear of blushing → sympathetic activation → actual blushing → reinforcement.
• Often co-occurs with social anxiety disorder (SAD).

Pathophysiology

Blushing: sympathetic → facial venous plexus dilation (β-adrenergic). In erythrophobia, hyperawareness and catastrophic appraisal ("everyone sees I'm anxious") amplify the response.

Treatment

• CBT: Cognitive restructuring (probability/cost of blushing), exposure (interoceptive, situational), attention training (external focus).
• SSRIs/SNRIs: First-line pharmacotherapy for comorbid SAD.
• Beta-blockers (propranolol): Situational use for performance blushing.
• ETS (endoscopic thoracic sympathectomy): Last resort; risks: compensatory hyperhidrosis, Horner's syndrome, gustatory sweating.

Outlook

Highly treatable with CBT. Many achieve remission or manageable symptoms. ETS reserved for severe, refractory cases after multidisciplinary review.
