What feeling is often associated with alcohol consumption due to its effect on blood vessels?

The feeling of warmth or glow that is often associated with alcohol consumption can be attributed to alcohol's ability to dilate blood vessels. When alcohol is consumed, it causes the blood vessels to expand, particularly near the surface of the skin. This expansion increases blood flow to the skin, which can create a sensation of warmth and a flushed appearance, commonly referred to as a "glow." This physiological response can make individuals feel cozy and more relaxed, even in cooler environments, reinforcing the perception of warmth that comes with drinking alcohol.
