<p>Why do we blush? This question has been puzzling scientists for years and various studies have been conducted to decipher this emotional arousal of human beings. Back in 1872, renowned British naturalist Charles Darwin described blushing as "the most peculiar and most human of all expressions". Researchers at the University of Amsterdam thought of going a layer deeper and conducted experiments on mostly female young people aged between 16 and 20 to reveal the science behind this phenomenon.</p>

<h2><strong>Two broad theories</strong></h2>

<p>There are majorly two theories behind blushing. One favoured by Darwin says our cheeks become red when we think about how we must look to other people or due to the fear of getting judged by other people.</p>

<p>The other theory doesn’t take other people's opinion into consideration and simply attributes blushing to the sense of feeling exposed.</p>

<p><strong>So, which theory is more dominant and pervasive?</strong></p>

<p>Dr Milica Nikolic, a psychologist and first author of the study, said, "Is it just being in the social situation where you are exposed and centre of attention, and you feel the exposure, and attention from others.”</p>

<p>Each volunteer was invited to the lab and asked to perform karaoke on camera.
