Temporary and involuntary reddening of the skin. Blushing can be brought on by excitement, exercise, fever, or embarrassment. Blushing occurs when the nervous system causes the capillaries of the skin of the cheeks and neck to widen, thus increasing blood flow that causes reddening.
Blushing refers to a transient reddening of the face, and occasionally the neck, resulting from the dilation of blood vessels near the surface of the skin. This reaction is often involuntary and commonly occurs in response to feelings of embarrassment. In some women, blushing can be observed as a characteristic symptom of hot flushes experienced during the menopausal period. Additionally, flushing of the face is associated with carcinoid syndrome, a condition characterized by the excessive release of certain hormones by neuroendocrine tumors. Understanding the causes and triggers of facial flushing can aid in managing and addressing the underlying factors contributing to this temporary reddening of the face.
