What your nose can tell you about your health

Rosacea is a long-term inflammatory skin condition that causes redness, rashes and visible blood vessels on the face, usually on the nose and cheeks krysvladimir/Shutterstock

Thanks to a quirk known as unconscious selective attention, your brain has learned to ignore your nose. A prominent feature that’s positioned closely to the eyes, the schnoz could get in the way of our vision – but the nervous system cleverly filters it out.

You can choose to look for your nose though. Either close one eye or look left, right or downwards and it’ll pop into view.
