Skin blushing or flushing occurs when the skin on the chest area, neck, or face turn red in color. Skin blushing or flushing may also cause the skin to feel warm as blood rushes to the area. Skin blushing or flushing is a common reaction to emotions, such as anxiety, embarrassment, nervousness, excitement, or anger. Health conditions, such as the skin condition rosacea, can also cause skin blushing or flushing, as can some medications (including those that treat high cholesterol and diabetes), drinking alcohol, or running a high fever. Eating foods that are very hot or spicy can also cause skin blushing or flushing.
