Blushing is normal – but here’s when it can be a problem
How blushing could actually have social advantages
- Blushing is an involuntary physiological response to emotions such as embarrassment or self-consciousness, caused by adrenaline increasing blood flow to the face, neck, or chest.
- This visible reddening, more noticeable in lighter skin tones, is triggered by the sympathetic nervous system, which causes blood vessels in the face to dilate.
- Evolutionary theories suggest that blushing acts as a social signal, conveying honesty or sincerity and helping to maintain social bonds after a perceived social misstep.
- Blushing frequency is influenced by factors including age, gender, and social anxiety, with women, younger individuals, and those with social anxiety typically blushing more.
- While blushing cannot be consciously prevented once it begins, severe or distressing cases may warrant medical attention, such as cognitive behavioural therapy or, rarely, surgical intervention.
