Blushing is uniquely human!
We’re the only animals that do it – blush. There are different types of blushing - blushing from embarrassment is part of our natural fight-or-flight response. When we get that surge of adrenaline - our breathing, heart rate and blood flow increase. It’s actually a very useful response. Not only do our cheeks get red – but our pupils dilate so we can take in as much visual information as possible. If you did need to fight or take flight in the midst of that akward moment – your senses are ready to rumble.
Crush blushing is a little different. If you REALLY like someone – and are physically attracted to them – your body temperature goes up – along with your sex drive and blood flow to the face.
