What Causes Blushing?

Do you blush easily? Aside from embarrassment, alcohol, exercise and spicy foods can all cause a blood rush to the skin. But according to Healthy Living, flushing can also be a sign of rosacea, a redness that affects people with fair, sun-damaged skin.

Sun damage weakens the collagen around blood vessels, so they lose their ability to constrict and instead stay dilated, which causes the face to become red.

It is best to use sun protection when going out in the sun and avoid the things that trigger flushing. You may consult your doctor about topical prescriptions if that doesn't work for you.
