Facial flushing occurs when the body pumps blood to the extremities, including the face, in an attempt to cool off during exercise. Similar to sweating, moving blood to the surface of the body can help release heat during a workout.
Normal Face Flushing
Normal face flushing occurs during a moderate to severe workout. If you are in a particularly warm environment, you may notice your face gets a little redder during your normal exercise.

Rosacea is a condition of the skin whereby a person gives off excessive heat through the face, even in normal circumstances. Rosacea can be noted by the patchiness of the red spots and the fact they do not go away after exercise. It is a nonthreatening condition.
Dehydration and Flushing
If your body is dehydrated, it may have difficulty sweating, causing more overheating. This can be a cause of excessive facial flushing. Drink plenty of water throughout the day and during exercise if you know you are prone to this problem.
Long-Term Facial Flushing
Facial flushing from exercise is common, but it should go away within 15 minutes of ceasing exercise. If your face or skin is still flushed for an extended period of time, you may have an undiagnosed skin condition or be seriously dehydrated.
Facial flushing can be caused by nervousness, anxiety, embarrassment or excitement. All of these are signs that your body is actually heating up slightly in physical response to emotions.
