Charles Darwin once said that blushing is the most peculiar and most human of all expressions. While it’s definitely a common response to embarrassment, anger, or maybe one too many drinks, this video explains what’s happening in our body and how blushing can actually be kind of endearing.
When your face turns red, you’re actually experiencing your body’s all-too-familiar “fight or flight” response, which involves an increased heart rate and dilated blood vessels to improve blood flow. Your cheeks are particularly sensitive to these changes and presumably turn red because of them.
Another plausible explanation for why we blush is that it’s like a non-verbal, physical apology for when you’ve done something socially unacceptable, like farting really loud in public. This social signal of regret or remorse makes you more relatable and likeable, so don’t be embarrassed by your blushing.
