Erythrophobia, the fear of blushing, explained

Erythrophobia is the fear of blushing. Not blushing, the fear of it. The distinction is the whole subject and it is the reason this article exists separately from the one about blushing itself.

It is not a standalone diagnosis in the main diagnostic manuals. In practice it sits inside social anxiety disorder, usually as the dominant complaint, and the clinical literature tends to describe it as social anxiety disorder with fear of blushing. Some of the strongest studies in this field recruit exactly that group, because they are a clean population: people whose social fear is organised around one visible bodily sign.

How it is different from blushing

Someone who blushes and does not fear it has a face that occasionally goes red. Someone with erythrophobia has a day shaped around the possibility.

The signs are behavioural rather than physical. Choosing seats by how visible they are. Declining or rerouting anything with introductions in it. Preferring written communication for reasons you have stopped questioning. Carrying makeup or a scarf as insurance. Rehearsing what you would say if somebody comments. Checking your reflection for evidence. Leaving conversations slightly early, before anything happens.

The strongest evidence that the fear and the blush are separable comes from a 2001 trial. Patients with fear of blushing were treated and their blushing was measured physiologically throughout. Fear of blushing dropped. Actual blushing did not change. The authors wrote that fear of blushing reflects a fearful preoccupation, irrespective of actual facial coloration.

People got better without their faces changing at all.

What is going on underneath

The 2020 review by Drummond, Shapiro, Nikolić and Bögels lays out the components. Physically, blushing is driven mainly by sympathetic adrenomedullary and neural vasodilator discharge, possibly with secondary neurovascular inflammation. Psychologically, the risk factors are social anxiety together with heightened self focused attention and inflated beliefs about how likely blushing is and what it will cost.

Those inflated beliefs have been measured directly. In one study, people who fear blushing overestimated both the probability and the interpersonal cost of blushing compared with controls. In the second experiment the researchers put the same situations to observers, and the observers' judgments matched the low fear group's predictions rather than the high fear group's.

The beliefs also run automatically, not just deliberately. Using an implicit association test, researchers found that people with fear of blushing associate blushing with social costs at an automatic level as well as an explicit one, which is part of why arguing with yourself about it in the moment does so little.

There is one more piece that is genuinely surprising. People who fear blushing appear to hold stricter beliefs about what counts as acceptable social behaviour in the first place. The bar is set higher, so more moments qualify as a breach, so more moments are dangerous.

The blush is not doing what you think it is doing

There is a body of work on what a blush communicates, and it does not support the interpretation most people who fear it are carrying.

In one experiment, participants played a game with an opponent who defected on them, then saw a photograph of that opponent either blushing or not. The blushing opponent was trusted with more money afterwards, judged more positively, and expected to defect less. The paper is called Saved by the blush.

The reading that follows is not that blushing is nice. It is that a blush is read by other people as evidence that you care what they think, and because it cannot be faked, it is believed. Which is close to the opposite of the meaning you have been assigning to it.

What has been tested as treatment

Task concentration training is the approach developed specifically for this problem. It trains attention outward, in graded steps, on the reasoning that self focused attention is what maintains the fear.

In a randomised trial of sixty five patients, task concentration training was compared with applied relaxation, both followed by cognitive therapy. Both were highly effective. Task concentration training was superior at one year follow up on fear of showing bodily symptoms, and superior at every assessment point on self consciousness and self focused attention.

A German team then tested it in an intensified group format against a waiting list, in eighty two patients. Task concentration training and cognitive therapy were both superior to waiting and equally effective, and at six month follow up remission rates among completers were between 69 and 73 per cent.

Exposure works too. In the 2001 study, exposure in vivo and task concentration training were both effective, with task concentration training tending to do better on fear of blushing at post test and producing more cognitive change at six weeks. By one year the difference had gone and both groups had improved further.

And there is a study specifically about people who do not go to therapists. Researchers designed a low threshold psychoeducational course, six weekly sessions, framed with participants and teachers rather than patients and therapists, because they had observed that people who fear blushing do not easily seek psychological help. Across forty seven participants it reduced fear of blushing and social anxiety, with a large effect, and that held at one year. It had no control group, so read it as promising rather than proven.

What is not established

Medication. The 2016 systematic review of propranolol for anxiety disorders found eight eligible trials, of which one was social phobia with sixteen participants. That is not enough to argue from in either direction. A doctor who knows you is the right person for this question.

Surgery. Endoscopic thoracic sympathectomy is discussed in its own article on this site. It is irreversible and the long term numbers deserve reading in full before anyone signs anything.

The thing worth taking away

It has a name. It has been studied by named researchers in named journals for over twenty five years. There are randomised trials. There are replications by independent teams. There are people whose academic careers are largely about this one problem.

If you have spent years assuming this was a personal defect too small and too silly to mention, that is the part worth sitting with for a minute.
