For a person to flush is to become markedly red in the face and often other areas of the skin, from various physiological conditions. Flushing is generally distinguished, despite a close physiological relation between them, from blushing, which is milder, generally restricted to the face or cheeks, and generally assumed to reflect embarrassment. Flushing and blushing can lead to rosacea. Flushing is also a cardinal symptom of carcinoid syndrome – the syndrome that results from hormones (often serotonin or histamine) being secreted into systemic circulation.

Causes of flushing

• sexual arousal (see section to follow)
• emotions: anger, embarrassment
• an abrupt cessation of physical exertion (resulting in heart output in excess of current muscular need for blood flow)
• physiological response to vasodilators, for instance, a recent high dose of niacin, nitroglycerine, calcium channel blockers, or any drug that causes release of adrenal hormones that raise blood pressure such as stimulants
• post-menopausal decrease in estrogen production
• anaphylaxis
• neuroendocrine tumors: carcinoid syndrome, pheochromocytoma, VIPoma, thyroid medullary carcinoma
• mast cell tumor: mastocytosis
• Niacin
• Various psychedelics or other drugs, such as 3-Quiniclidinyl Benzilate(BZ) or Alcohol

Sex flush

Commonly referred to as the sex flush, vasocongestion (increased blood flow) of the skin can occur during all four phases of the human sexual response cycle.

The sex flush tends to occur more often under warmer conditions and may not appear at all under cooler temperatures.
