causes of face feeling hot
This is caused by the dilation of blood vessels in the face and neck, which allows blood to rush to the head. This, in turn, causes the skin to feel warm and turn red. Generally, people with fair skin and younger people are most susceptible to hot face and ears caused by blushing.
1 The skin condition known as rosacea can also cause hot face and ears. Other symptoms include broken veins and redness.  The condition can also be a sign of carcinoid syndrome. Hormone releasing tumors in the appendix, bronchial tubes, colon or small intestine cause this syndrome.
