Although many of these conditions could leave you red in the face – blushing is brief, milder, and often seen as a reflection of embarrassment, guilt or nervousness. Other causes include spicy foods, high fever, exercise, certain drugs and the menopause, where women experience the infamous hot flushes. Blushing happens when tiny muscles in the blood vessels relax allowing more blood to pass through, whilst flushing makes the person markedly red on the face and other areas of the skin. The latter can be brought on by lots of reasons similar to blushing, but allergic reactions and dehydration can contribute to this. Rosacea, on the other hand, is a condition that looks like a flush or a blush, and can progress from persistent to intermittent redness with pimples without blackheads and red lines where the blood vessels of the face become prominent. Aggravated by certain foods and environments, rosacea responds to treatment but is incurable.
